ADAMS/Car轮毂电机驱动大学生方程式赛车悬架结构设计与分析

摘要悬架是汽车的重要组成部分。对于 FSAE 赛车而言，悬架主要影响赛车的操纵稳定性和行驶平顺性。本文主要针对与轮毂电机配合大学生方程式赛车的悬架设计，其一是对于悬架的总体设计，其二完成轮毂电机的安装及其干涉问题。通过查阅《汽车设计》和相关论文解决上述两个问题。总体上提出了不等长双横臂螺旋弹簧独立悬架的悬架设计方案，以及轮辋-轮毂-电机-刹车盘-立柱的电机安装方案。并利用 ADAMS/Car 对悬架进行建模仿真，得到在轮跳为-30mm 至 30mm 范围内，车轮外倾角、车轮前束、主销内倾角、主销后倾角的变化。给出悬架设计的合理性以及不足改进的地方。69541

Title Wheel motor driving FSAE racing car suspension structure design and analysis

Abstract

The suspension is an important part of the car.For FSAE car, the car's suspension mainly affects handling stability and ride comfort.This paper aims to solve the problem of suspension designs for the Formula Student racing car driven by wheel motor.On the one hand，give the overall design of the suspension, and on the other hand to complete the installation of the motor hub and solve the interference issues.Now to solve the above two problems by 《car design》 and related papers.It proposes the suspension design of unequal length double wishbone independent suspension with coil spring in general，And rims - hub - motor - brakes - uprights motor mounting scheme.Using ADAMS / Car to build model and simulate the suspension.Then get the changes of camber, toe-in, kingpin inclination, caster angle when the wheel hop within the range of 30mm to -30mm.Give the rationality and improvement of suspension design.

Keywords FSAE racing car suspension design wheel motor Interference
