FSAE电动赛车多连杆式后悬架结构设计与分析
摘要：本毕业设计对FSAE赛车后悬架的结构及特点进行比较，综合比对选取适合的后悬架类型；我们最后决定FSAE赛车的后悬架选用多连杆结构。根据赛车参数，进行了大量的计算，根据数据确立了后悬架的尺寸，材料，以及悬架部件的选取以及参数，然后利用 proe 建立 FSAE 赛车后悬架的三维机构仿真模型；在建立三维模型的过程中，根据坐标来建立三维模型，这样的精度高。将三维模型导入有限元软件ANSYS 中，进行静力学计算，以及动态分析，对后悬架下控制臂的0.5g加速工况，0.95g转弯工况的应变和应力进行分析，最后证实了设计满足要求，且存在安全富裕度。然后进行共振分析，分别选取了五种状态下的振型与固有频率进行比较，来判断下控制臂的结构和材料是否满足设计要求，经过比较得出了下控制臂满足设计要求。

Abstract:After the graduation design of FSAE car suspension structure and characteristics of comparison, choose the right rear suspension structure types; The FSAE car suspension parameter calculation,then The FSAE car rear suspension was established based on CATIA 3 d model; Establishment of ADAMS/Car suspension and a simulation model of virtual simulation analysis was carried out on the rear suspension of variation is larger suspension parameters optimization using ADAMS/Insight module; The CATIA model into ANSYS, the static calculation, the suspension column under static, steering and braking conditions of strain and stress were analyzed, and to determine whether a column structure and materials meet the design requirements.Under the environment of ADAMS/Car,Control arm to the traditional process of casting or forging, using the casting and forging can not only save costs, and can lay a foundation for parts of the whole control arm design. In addition, the control arm parts are large stamping equipment, although it into during increased manufacturing difficulty, but it makes a connection with the interchangeability, and the loss of castings and forgings connection part after school as soon as possible to replace the entire assembly. This paper discusses the control arm is made of steel plate stamping forming process, and established the virtual simulation model of automobile suspended frame suspension dynamic simulation analysis. Through the finite element software ANSYS finite element theory and method to create the finite element model, 0.5 g acceleration condition, 0.95 g to jump condition on the working condition and 3.5 g. Stress and strain analysis.
