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.

Formula Student Race Car Chassis Design and Analysis

Formula Student, an official project competition organized by the SAE (Association of Automotive Engineers), allows university Students around the world to develop their knowledge in the automotive field by aiming to design a Formula-type race car using their own knowledge. In this study, the chassis system of Formula Student race car was redesigned with SolidWorks 2018 program, taking into account the design criteria. The optimization studies were carried out to determine the strength of the chassis system against to mechanical stress using ANSYS 16.0 and SolidWorks Simulation programs. After the chassis design, front impact analysis, rear impact analysis, side impact analysis, front torsional stiffness analysis and rear torsional stiffness analysis were performed. In this study, it was determined that the chassis designed to be used in Formula Student race car has more than enough design criteria and rigidity as a result of the analysis. As a result of the analysis, lighter and more rigid designs were obtained by narrowing the target design criteria, taking into account the competition rules. Although the redesigned vehicle chassis in this study is 30% heavy compared to its equivalents, it is quite superior in terms of rigidity and ergonomics
