摘要
电动汽车取消了传动系统和发动机系统,其运行原理与传统燃油车完全不同,需要重新定义、设计专用底盘以满足其平顺性。试验人员设计了一款轻型两座电动汽车底盘,利用ADAMS动力仿真软件搭建和设计仿真试验,利用ADAMS特有的动力学分析处理功能提取并量化底盘的振动值,做成表格进行底盘平顺性对比,择选出轻型轮毂电机电动汽车的最优底盘形态为田字型而非传统的H型。该方法可进一步应用到其他类型电动汽车底盘的设计中。
Electric vehicle has elim inated the transmission system and engine system,its principle is completely different from that of a conventional fuel vehicle.It is necessary to redefine and design a special chassis to meet its ride comfort.The experim enter designed a lightweight two-seat electric vehicle chassis,built and designed a simulation test using ADAMS dynamic simulation software,extracted and quantified the vibration values of the chassis before and after optimization using ADAMS's unique dynamic analysis processing function,made a table for chassis smoothness comparison,and selected a light hub motor.The optimal chassis shape for a car is a field type rather than a traditional Htype.This method can be further applied to the chassis design of other types of electric vehicles.
