FSAE电动赛车前悬架结构设计与分析【双横臂式悬架】
摘要：本设计对FSAE赛车前悬架的结构及特点进行比较，综合比对选取适合的悬架结构形式，最终确立FSAE电动赛车的前悬架采用双横臂式悬架结构；根据赛车参数，进行了大量的计算，根据数据确立了前悬架的尺寸，材料，以及悬架部件的选取以及参数，对影响安全性的零件，例如横向稳定杆和缓冲块都有明确的计算与设计，然后进行ADAMS建模、优化，最终确认主销外倾角，主销内倾角，均满足设计要求。随之选用 proe软件对FSAE前悬架实施3D图形的创造；在建立三维模型的过程中，根据零件的三维坐标，生成三维模型，这样的精确度高。再后，使用有限元分析软件ANSYS对整体结构进行静态分析和动态分析，在静态分析中，均符合设计要求，在动态分析中，着重对在0.5g加速状态和0.95g转弯状态下进行有限元分析，前悬架下控制器在这两种严格的工况下，所产生的应力集中问题，和应力变形问题，对这两种问题进行分析比对，对应力集中现象，都小于材料的屈服极限，说明满足安全的要求，对应力变形问题，也同样满足设计要求。本次FSAE赛车的前悬架完全符合设计要求。

Design and Analysis of Front Suspension Structure
of FSAE Electric Racing
Abstract：This graduation design the structure and characteristics of FSAE car front suspension is used in the comparison, comprehensive than to choose a suitable suspension structure, finally established FSAE electric car front suspension with double wishbone type suspension structure;According to the parameters of car, a large amount of calculation, based on the size of the data to establish the front suspension, materials, and the selection of suspension components and parameters, affecting the safety of spare parts, such as the horizontal stabilizer bar and buffer blocks are clearly calculation and design, then, ADAMS, modeling, optimization and finally confirm the king pin camber Angle, kingpin inclination Angle, meet the design requirements.Then using proe FSAE car front suspension three-dimensional organization simulation model is set up;In the process of establishing three-dimensional model, according to the components of the three-dimensional coordinates, generated 3 d model, the precision is high.Again later, using the finite element analysis software ANSYS static analysis and dynamic analysis was carried out on the whole structure, in static analysis, all comply with the design requirements, in the dynamic analysis, the state of accelerating in 0.5 g and 0.95 g condition in finite element analysis of turning, the front controller in both the strict conditions, the stress concentration problems, and stress deformation problem, the analysis of the two kinds of problems, the stress concentration phenomenon, are less than the yield limit of material, that meet the requirements of safety, the deformation and stress problem, also meet the design requirements.The FSAE car front suspension fully comply with the design requirements.analysis controller.
