FSEC赛车车架设计与仿真

Design and Simulation of FSEC Racing Car Chassis

为了提高学生对赛车车架的设计与优化能力,汽车工程师协会(SAE)举办了“中国大学生方程式赛车”——FSEC竞赛,其资格赛项目(MQP)的要求便是设计一款赛车并进行竞速比赛。MQP要求学生通过设计、制造和评估车辆的性能,来提高其专业能力,这种方法广泛应用于机械、电气、制造、航空航天等各个领域。本文将极限载荷施加在赛车前立柱上,在三种不同的场景下,优化赛车的车架模型,并确认了强度、刚度和安全系数。结果表明,优化后的模型在强度和刚度上符合设计要求,安全系数较高,可以为后续的设计提供依据。

In order to improve students’ability to design and optimize racing chassis,the Society of Automotive Engineers(SAE)held the"Formula China Student Racing"competition,and its qualification program(MQP)required the design of an FSEC car and racing.MQP requires students to improve their application capabilities by designing,manufacturing,and evaluating the performance of real vehicles,which is widely used in mechanical,electrical,manufacturing,aerospace and other fields.This article applies extreme loads to the front column of the race car,simulates the optimized model in three different scenarios,and confirms the strength,stiffness and safety factors.In this paper,SolidWorks is used to model and simulate the frame of the formula student race car,and the results show that the optimized model meets the design requirements in terms of strength and stiffness,and has a high safety factor,which provides a basis for subsequent manufacturing.
