摘　　要：赛车制动系统的好坏不仅影响着赛车的操纵性能,更影响着赛车的行驶安全性能。基于FSC比赛规则与某赛季的整车参数与实测数据,确定了制动回路的布置形式。为了提高整车制动性能,通过对赛车整车受力分析,并根据赛道附着系数,计算出制动器相关参数,优化前后制动力分配,以解决之前赛季出现的制动力过剩的问题。通过计算,确定制动踏板所能承受的最大力,利用CATIA,CAXA对制动踏板进行建模,并用ANSYS和Workbench软件对其进行有限元分析,然后,利用ANSYS的Shape Optimization模块对其进行拓扑优化,确定制动踏板形状尺寸,最终建模并利用ANSYS Workbench软件进行校核。The quality of the car brake system not only affects the car's handling performance,but also affects the driving safety of the car.Based on FSC competition rules,vehicle parameters and measured data of a season,the layout of brake circuit is determined.In order to improve the braking performance of the whole car,through force analysis of the racing car,and according to the track adhesion coefficient,the brake related parameters are calculated,and the distribution of front and rear braking force is optimized to solve the problem of excess braking force in previous seasons.Through calculation,the maximum force that the brake pedal can bear is determined.CATIA and CAXA are used to model the brake pedal,and ANSYS and workbench software are used to carry out the finite element analysis.Then the shape optimization module of ANSYS is used to optimize the topology of the brake pedal.Finally,the shape and size of the brake pedal are determined.Then the model is built and checked by ANSYS Workbench software.
