Design of SUPRA-SAE Student Version (A Review)

Abstract: The most important part of any vehicle is the Chassis. The chassis is the support system for all components in the vehicle. It is responsible for supporting all functional systems of a vehicle and accommodates the driver in the cockpit. Therefore, its design must sustain the weight of the components. Designing a chassis for driver’s safety is always been a concern, especially for a race car. In this report, a few techniques are mentioned on how to analyze a formula student race car chassis to ensure its structural stability for the driver’s safety

Formula Student Race Car Chassis Design and Analysis

SAE (The Society of Automotive Engineers) tarafından düzenlenen resmi bir proje yarışması olan Formula Stu-dent, dünya çapında birçok üniversite öğrencilerinin kendi bilgi birikimlerini kullanarak belirlenen kurallara uygun bir şekilde Formula tipi bir yarış arabası tasarlamasını amaçlayarak, öğrencilerin otomotiv sahasındaki bilgilerini geliştirmelerine imkan tanımaktadır. Bu çalışmada SolidWorks 2018 programı ile Formula Student yarış aracının şasi sistemi tasarım kriterleri dikkate alınarak yeniden tasarlanmıştır. ANSYS 16.0 ve SolidWorks Simulation programları kullanarak şasi sisteminin mekanik zorlanmalara karşı olan dayanımlarını belirlemek için optimizas-yon çalışmaları yapılmıştır. Şasi tasarımı yapıldıktan sonra şasinin ön darbe analizi, arka darbe analizi, yan darbe analizi, ön torsiyonel rijitlik analizi ve arka torsiyonel rijitlik analizi yapılmıştır. Bu çalışmada Formula Student yarış aracında kullanılmak için tasarlanan şasinin, gerçekleştirilen analizler doğrultusunda, hedeflenen tasarım kriterleri ve rijitlik derecesine fazlasıyla sahip olduğu belirlenmiştir. Yapılan analizler neticesinde yarışma kuralları doğrultusunda, hedeflenen tasarım kriterleri daraltılarak daha hafif ve rijit tasarımlar elde edilmiştir. Bu çalışmada yeniden tasarlanan araç şasisi muadillerine göre bir nebze (%30) ağır olsa da, rijitlik ve ergonomik olması bakımın-dan oldukça üstündür.

Design and static structural analysis of a race car chassis for Formula Society of Automotive Engineers (FSAE) event

The main purpose of this study is to make improvement for the UniMAP Automotive Racing Team car chassis which has several problems associated with the chassis must be fixed and some changes are needed to be made in order to perform well. This study involves the process of designing three chassis that are created based on the rules stated by FSAE rules book (2017/2018). The three chassis will undergo analysis test that consists of five tests which are main roll hoop test, front roll hoop test, static shear, side impact, static torsional loading and finally one of them will be selected as the best design in term of Von Mises Stress and torsional displacement. From the results obtained, the new selected chassis design which also declared as the new improved design poses the weight of 27.66 kg which was decreased by 16.7% from the existing chassis (32.77 kg). The torsional rigidity of the improved chassis increased by 37.74%.

Determination of Natural Frequencies through Modal and Harmonic Analysis of Space Frame Race Car Chassis Based on ANSYS

Space frame chassis the preferred choice of chassis design due to its low cost, high strength, lightweight and safe qualities, which made it suitable for a single-seat race car application and an important aspect in the construction of the space frame race car chassis. Key sections of a space frame race car chassis consist of front and main hoops, side impact protection and crush zone sub-frame. These sections are pivotal in the safety aspect of the driver during emergency situation. This research introduces several methods of dynamic analysis to investigate the mode shape and natural frequencies in the chassis structure. Two methods are mainly used in the study, modal analysis and harmonic analysis with both analyses are performed using Finite Element (FE) method through Finite Element Analysis (FEA) software packaged, ANSYS v13 APDL Mechanical. The study identified five mode shapes extracted using Block Lanczos method, all mode shapes vibrated at a frequency above 150 Hz with the characteristic of each mode shapes is further explained in this study. Amplitude vs. frequency graph is generated from harmonic analysis is utilised to determine the resonance frequency. The highest amplitude occurred in the third natural frequency with an amplitude of 0.375 mm. The outcome of this analysis can be used as a reference in improving the chassis design and performance against dynamic behaviour of the structure by introducing stiffener on part of the chassis imposed with the highest displacement.

Design and Analysis of SUPRA AISI 1018 Carbon Steel Car Frame Using ANSYS

In this competitive world, Speed is everything people are crazy on faster things. Speed is their passion either an automobile or any consumer appliances. The faster you get served better the returns expected. Economic value of automobiles is a factor which is dominated by the speed and pickup of the vehicle. In this project effort is made inDesigning and Analysis of the formula one race car chassis using ANSYS software. The Chassis is designed in Solid works, Meshingand Analysis is carried out in ANSYS. To enhance the speed and efficiency, aerodynamic modifications of the car profile is done and also to be float in a dynamic condition, weight is a vital parameter to be considered hence material change is also employed.

Development of formula varsity race car chassis

Three chassis designs have been developed using commercial computer aided design (CAD) software. The design is based on the specifications of UTeM Formula VarsityTM 2012 (FV2012). The selection of the design is derived from weighted matrix which consists of reliability, cost, time consumption and weight. The score of the matrix is formulated based on relative weighted factor among the selections. All three designs are then fabricated using selected materials available. The actual cost, time consumption and weight of the chassis's are compared with the theoretical weighted scores. Standard processes of cuttings, fittings and welding are performed in chassis mock up and fabrication. The chassis is later assembled together with suspension systems, steering linkages, brake systems, engine system, and drive shaft systems. Once the chassis is assembled, the studies of driver's ergonomic and part accessibility are performed. The completion in final fittings and assembly of the race car and its reliability demonstrate an outstanding design for manufacturing (DFM) practices of the chassis.

The performance of aluminium to carbon fibre composite bonded joints in motorsport applications

Race car manufacturers have been adhesive bonding composite monocoques for more than 15 years. The latest Grand Prix cars have more than 60 bonded joints and there is increasing interest in structural bonding of dissimilar materials. However, static strength and fatigue durability data for designing adhesive bonded joints between metallic and composite components in a race car chassis are likely to be over-conservative when generated using standard single lap joint bonded specimens. Experimental work has been carried out using modified single lap joint specimens to generate fatigue and static strength design data for the case of an aluminium alloy bonded to carbon fibre composite using a cold cured epoxy adhesive. Test specimens were modified by changing the ratio of the width of the carbon fibre to aluminium adherends in the range from 1:1 to 2:1 to provide a better representation of the case of small metal components being attached to larger composite structures. The mean static strength of the standard single edge lap specimens with a 1:1 width ratio of adherend was 22% lower than the specimens with wider carbon fibre composite adherends. Modifying the aluminium adherend in the 2:1 width ratio specimens by changing the end from square to semicircular increased the mean static strength by a further 23%. The 2:1 width ratio specimens also had substantially increased fatigue lives compared with the standard 1:1 width ratio specimens. At a nominal shear stress range of 12 MPa and R ratio of 0.06, the mean fatigue life of the wider specimens was increased by almost a factor of five. Examination of the failed specimens supported the hypothesis that the edges of the bonded area are the dominant factor in the failure process. The practical outcome of this work is to question the use of standard test geometries when generating strength and durability data for the design of adhesive bonded components for motorsport applications.
