Effect of Heat Treatment Temperature on Hardness and Micro Structure Change of Assab 705 Steel as a Die Mould Material

The mould is most imfortance tools for large production for example in automotive industry. The cost of mould is highly dependant on part geometrical complexity and material selection. Steel has long been used as a material for making moulds, although new materials such as plastics and composites have been discovered. However, steel maintains its position above material selection because of its mechanical properties. This research uses Assab 705 steel, because Assab 705 steel is classified as medium carbon steel (carbon content of 0.38-0.43%) and has the ability to be hardened through a heat treatment process. Application of Assab 705 steel is widely used for making bolts, tools and various kinds of moulds. The heat treatment process carried out in this study is by heating the steel sample with a temperature variation of 750, 800, 850 and 900°C and continued with the quenching process using Olie SAE 90 as cooling media. Steel samples that had been heat treated were tested by Rockwell hardness and micro structur changes were analyzed using optical microscope. Based on the results of rockwell hardness testing that the highest hardness value was achieved at 54.5 HRC in samples that have been heat treated at 900°C, which when compared to hardness samples without heat treatment, there has been an increase of 60.30%. The microstructure of the Assab 705 steel sample changed after the heat treatment process, which formed a martensite phase and tended to increase with increasing heat treatment temperatures.

SAVE: Security & safety by model-based systems engineering on the example of automotive industry

Cyber-physical systems (CPS), like autonomous vehicles, are intelligent and networked. The development of such systems requires interdisciplinary cooperation between different stakeholders. A lack of system understanding between stakeholders can lead to unidentified security threats & safety hazards, resulting in high costs in product development. In particular, a lack of an integrative consideration of security threats & safety hazards can compromise safety compliance for CPS. Model-based systems engineering (MBSE) improves the understanding of systems between stakeholders by additionally creating supporting models. However, MBSE approaches only partially address security threats & safety hazards. In particular, their integrative consideration is not taken into account. Established security & safety approaches either are only applicable to specific disciplines or only partially consider security threats & safety hazards. In this paper we present a method that enables the early identification of safety relevant security threats. The method is designed to be applied in workshops with an interdisciplinary team of stakeholders and is used to determine initial results for the system architecture design phase. We illustrate our approach with the example of the automotive sector. To build a realistic system architecture we identified 18 architectural vehicle components including relevant architectural constraints. Finally, we present an evaluation of the method, based on a workshop with 30 master students.

Strategic Planning of Cars Quality in Operation

Abstract Attainment of high competitiveness indicators of products and services is a natural goal of each enterprise. This goal stems from the desire of stakeholders to ensure the continuous, long-term development of a company and the high performance of labour results. However, the market has leaders and outsiders for various reasons. And the outsiders can be decently prepared in organizational and technical terms. But something prevents them from successfully developing. In addition, a decision of methodological and analytical tasks is not cheap. Competent experts, relevant technical and technological support of the process, and, most importantly, the conditions for creative work are required.

The major extension refers to communication issues, based on an approach of social system theory. The research uses the example of automotive industry.

Regional strategic groups as a tool of enterprises localization analysis on the example of automotive industry in the European Union

Due to ongoing processes of globalization and internationalization, the enterprises localization selection is multi-aspect and multi-stage process. Therefore, there is a need for new solutions application, or at least modification of localization management methods. This paper presents an attempt of an application of modified McKinsey matrix for spatial analysis using an original concept of regional strategic groups. Regional strategic groups are the clusters of regions similar as regards sector attractiveness, as well as competitive position or potential. The aim of this elaboration is presentation of an application possibilities and limitations of regional strategic groups in strategic options management on the example of automotive industry enterprises operating in the regions of the European Union NUTS 2 level. The elaboration constitutes the proposal of an application of investment attractiveness of the regions valuation for an analysis of strategic options in global enterprise management. It was demonstrated during the research that an analysis of regional strategic groups may be applied in strategic management both from the position of the regions as well as the enterprises localized on their area. Application limitations of the method discussed include inter alia difficulty in reflecting of real inter-regional relations on NUTS 2 level and presentation of statistical data according to enterprises head offices not their actual deployment.

Towards Overcoming the Boundaries between Manufacturing and Perceived Quality: An Example of Automotive Industry

Automotive manufacturing enterprises face many challenges today. Remaining as one of the biggest among them is delivering value to the customers through product quality. Moreover, good manufacturing or technical quality does not always result in high perceived quality from a customer perspective. At the same time, perceived quality is a property that has to be incorporated into the product during the whole product lifecycle, from design to production. Throughout the production stage, every manufacturing operation contributes to the building of final product's perceived quality. Thus, there is a need to control manufacturing operations related to this matter. This paper addresses the connection of the perceived quality framework, which defines dimensions of the perceived quality, to a manufacturing model that represents the manufacturing variation and propagation during different assembly operations. The aim of the study is to overcome boundaries between manufacturing and perceived quality. An industrial example, within the automotive premium sector, has been used to draw this connection illustrating the case of welded assemblies.

Gazdaságfejlesztés az ingolstadti járműipari központban

Napjainkban a kelet-közép-európai gazdasági folyamatokban a járműgyártás jelentős szereppel bír. A járműipari központok fejlődése hozzájárul az adott település, a várostérség, sőt akár az egész ország gazdasági növekedéséhez és fejlődéséhez. Ugyanakkor e központok is számtalan kihívással szembesülnek, melyek megoldásához a résztvevők együttműködésére van szükség, mint ahogy a gazdasági fejlettség szinten tartásához és növeléséhez is.A tanulmányban az ingolstadti járműipari körzetet vizsgálom, különös tekintettel a járműipar (és az Audi AG) városfejlődésre gyakorolt hatására, valamint a térség gazdasági szereplői, felsőoktatási intézményei együttműködésének modelljére. Megvizsgálom a város infrastrukturális adottságait, valamint az önkormányzat helyi gazdaságfejlesztésben betöltött szerepét, elemezve azokat az önkormányzati társaságokat és beruházásokat, melyek hozzájárultak a város gazdasági telephelyminőségének növeléséhez (gazdaságfejlesztési társaság, logisztikai park, kutatás-fejlesztési központ, vállalkozásfejlesztési társaság, telekommunikációs vállalat stb.). A tanulmány célja, hogy feltárja az ingolstadi járműipari központban végbemenő folyamatokat, együttműködéseket és jó gyakorlatokat annak érdekében, hogy megfogalmazhassa az ingolstadti járműipari központ gazdaságfejlesztési modelljét. A gazdaságfejlesztési modell megalkotása pedig támpontként szolgálhat más, jelenleg kialakuló, továbbá már működő járműipari központok fejlesztési irányainak kijelöléséhez.

Numerical and Experimental Investigations of the Production Processes of Coextruded Al/Mg-Compounds and the Strength of the Interface

Due to a changing environmental awareness and the improved use of resources, the application of light-weight materials, such as aluminium and magnesium, becomes increasingly important and partially substitutes the utilisation of conventional materials such as steel. However, a widespread application demands a better understanding of these materials. This concerns production processes of semi-finished products and the products itself. Coextruded aluminium-magnesium compounds are investigated in the subproject B3 (“Experimental and numerical investigations of the interface behavior of Al-Mg compounds”) which is part of the special research area 692 – HALS at the Chemnitz University of Technology. These compounds are characterized by a very good weight-strength-ratio and allow a wide field of application, for example in automotive industry. The compounds are manufactured in extrusion processes. The interface which is developed during the production is of special interest and the investigation of it is a shared aim of the Department of Experimental Mechanics and the Department of Virtual Production Processes. The two main tasks are the extrusion process optimisation and the microstructural, mechanical and thermal examination of the semi-finished product. The following paper gives an overview of the performed investigations in this subproject.

Numerical prediction of the foam structure of polymeric materials by direct 3D simulation of their expansion by chemical reaction based on a multidomain method

The quality of thermosetting polymer foams (like polyurethane foam, used for example in automotive industry) mainly depends on the manufacturing process. At a mesoscopic scale, the foam can be modelled by the expansion of gas bubbles in a polymer matrix with evolutionary rheological behaviour. The initial bubbles correspond to germs, which are supposed quasi-homogeneously distributed in the polymer. An elementary foam volume (∼1 mm3) is phenomenologically modelled by a diphasic medium (polymer and immiscible gas bubbles). The evolution of each component is governed by equations resulting from thermodynamics of irreversible processes: the relevant state variables in gas, resulting from chemical reaction creating carbon dioxide (assimilated then to a perfect gas), are pressure, temperature and conversion rate of the reaction. The number of gas moles in each bubble depends on this conversion rate. The foam is considered as a shear-thinning viscous fluid, whose rheological parameters evolve with the curing reaction, depending on the process conditions (temperature, pressure). A mixed finite element method with multidomain approach is developed to simulate the average growth rate of the foam during its manufacture and to characterize the influence of the manufacturing conditions (or initial rheological behaviour of the components) on macroscopic parameters of the foam (cell size, heterogeneity of porosity, wall thickness).
