基于ADAMS对轮毂电机专用底盘的平顺性优化
|
摘要
设计并轻量化处理了一款轻型两座轮毂电机驱动型汽车底盘,轻量化处理后底盘质量为400 Kg,导入ADAMS软件中设计并搭建试验环境,重新设计和定义了本型号专用底盘最优底盘重量为550 Kg,然后多次利用关键位置配重和次要位置轻量化的原则,再次重新分配底盘重量和改变底盘形态,并利用ADAMS特有的动力学分析处理功能提取振动加速度曲线,根据振动加速度曲线量化处理各个底盘成品的振动值,做成对比表格进行底盘平顺性对比,择选出本型号专用底盘最优形态为连接孔处加重75 Kg,其他薄弱环节加重75 Kg。
A lightweight two-wheel hub motor drive car chassis is designed and lightweight processed. After lightweight processing,the chassis quality is 400 Kgs. The design and test environment are introduced into the ADAMS software,and the optimal chassis weight of this model is redesigned and defined. 550 Kgs,then repeatedly use the principle of weight distribution in key positions and lightweight in secondary positions to redistribute chassis weight and change chassis morphology,and use ADAMS's unique dynamic analysis function to extract the vibration acceleration curve,and quantify the vibration value of each chassis product based on the vibration acceleration curve,The comparison table is made to compare the chassis smoothness,and the optimal form of this model's dedicated chassis is selected as 75 Kgs for the connection hole,and 75 Kgs for other weak links.
