Dynamic Modeling and Simulation Analysis of Virtual Product Design and Creation Based on OSG Artificial Intelligence Platform

The creation of Koji Pottery art is a creative act that has risen rapidly in recent years. The difference in the proportion of ingredients in the glaze directly affects the roughness, luster, and glaze of the glazed surface of the work. The curve of heating and cooling is also the key to the success or failure of the work. Therefore, taking the Koji tea bowl shape as a research example, a virtual reality simulation system and an OSG (OpenSceneGraph) artificial intelligence platform are used to construct a Koji tea bowl shape simulation model, and then the physical production is performed according to the model. After the design and production of the Koji tea bowl shape, the RTM (resin transfer molding) model is used to evaluate the process quality standard requirements of the Koji bowl shape. According to the RTM model test results, the homogeneity test results show that the result is much larger than 0.10, from which it can be inferred that the Koji tea bowl shape has reached the national process quality standard requirements. At the same time, the OSG artificial intelligence platform uses the iterative random sampling method to extract and display the abnormal data in the simulation model, which greatly improves the success rate of ceramic creation. In this paper, the creation and simulation of virtual ceramics based on OSG artificial intelligence platform are deeply studied and analyzed, and the related processes are improved, which reduces the difficulty of software operation and improves the creation efficiency.

Emerging CAE technologies and their role in Future Ambient Intelligence Environments

AbstractDramatic improvements are on the horizon in Computer Aided Engineering (CAE) and various simulation technologies. The improvements are due, in part, to the developments in a number of leading-edge technologies and their synergistic combinations/convergence. The technologies include ubiquitous, cloud, and petascale computing; ultra high-bandwidth networks, pervasive wireless communication; knowledge based engineering; networked immersive virtual environments and virtual worlds; novel human-computer interfaces; and powerful game engines and facilities. This paper describes the frontiers and emerging simulation technologies, and their role in the future virtual product creation and learning/training environments. The environments will be ambient intelligence environments, incorporating a synergistic combination of novel agent-supported visual simulations (with cognitive learning and understanding abilities); immersive 3D virtual world facilities; development chain management systems and facilities (incorporating a synergistic combination of intelligent engineering and management tools); nontraditional methods; intelligent, multimodal and human-like interfaces; and mobile wireless devices. The Virtual product creation environment will significantly enhance the productivity and will stimulate creativity and innovation in future global virtual collaborative enterprises. The facilities in the learning/training environment will provide timely, engaging, personalized/collaborative and tailored visual learning.

Competing in engineering design—The role of Virtual Product Creation

Product creation is facing the next level of fundamental changes. Global demands are growing substantially to achieve energy efficient and sustainable value creation networks for production, products and services without compromising traditional success factors such as time to market, cost and quality. To stay competitive within such an environment development partners in industry and public sectors will require new interplay solutions for engineering design execution, domain knowledge representation, expert competence utilization and digital assistance systems. This scenario offers the chance for virtual production creation solutions to become critical for the future by offering unique engineering capabilities, which have not yet been explored or deployed. The paper investigates key elements of modern Virtual Product Creation – such as agile process execution, functional product modeling and context appropriate information management – towards their competitive role in satisfying increasing numbers of product requirements, in delivering robust systems integration and in ensuring true sustainable product lifecycle solutions.

Towards hybrid modelling environments—Merging desktop-CAD and virtual reality-technologies

Immersive virtual environments are a important technology within the overall toolset of virtual product creation [1]. Immersive modelling systems which allow for creating product models receive interest from both academic research and industry [2–4]. This paper describes three empirical studies on immersive modelling techniques conducted with 52 industrial designers, engineers and design students. Based on the results of these studies, a methodology for hybrid modelling environments is introduced and exemplified. This methodology enables designers and engineers to solve spatial, interactive and creative design tasks in immersive, collaborative environments while maintaining CAD modelling as a familiar design method.

New potentials for virtual product creation by utilizing grid technology

Efficient virtual product creation combined with predictive engineering requires high-capacity computing and communication technologies as well as fast and transparent supply of knowledge, information and data. For this purpose, grid technologies offer great potentials for virtual product creation. One objective of grid computing is to perform more realistic simulations for better prediction of effects with reduced costs. This paper describes the approach and methods how engineering analysis problems in product development and manufacturing can be solved in the flexible context of CAE applications and grid computing infrastructure. The presented results are partly achieved in a joint project with partners from research and industry.

Application of Virtual Assembly Tools for Improving Product Design

Virtual product creation and product design analysis are essential for studies in the investigation into assembly feasibility and help reveal practical manufacturing constraints. This paper demonstrates an application of a virtual assembly tool DYNAMO for a grill plate assembly. Virtual simulation and assembly verification is illustrated. Both virtual simulation and assembly verification enable designers to identify potential assembly difficulties encountered in manufacturing and thus save time and cost in real production. The paper also examines factors that influence the efficiency of assembly, namely, assembly method, assembly sequence, and assembly time. Suggestions for redesign for assembly improvement provided by some design for assembly methods are also discussed.
