汽车控制臂衬套对汽车的操控性和舒适性都有很大影响,分析橡胶臂衬套在整车载荷中的变形规律对于产品设计和验收有很大意义。该文首先分析了控制臂衬套在整车中的受力特点;然后进行了橡胶部件的力学性能实验,确定了材料模型和参数;对控制臂衬套在球头销处承受整车x向和y向载荷的工况进行了仿真。结果表明控制臂衬套在该文安装方式下,整车x向力下后衬套的变形接近K1方向;在整车y向载荷下,后衬套变形可以忽略,载荷主要由...
针对角接触球轴承动态刚度和阻尼特性分析的问题,本文建立了考虑基础响应的单自由度动态参数测试力学模型;搭建了轴承动态参数识别试验装置,测试及分析了不同的载荷条件对轴承径向和轴向动态刚度及阻尼的影响。试验结果表明:随着轴向载荷增大,轴向刚度、径向刚度逐渐增大,轴向阻尼、径向阻尼先减小后增大;随着径向载荷增大,轴向刚度、径向刚度逐渐增大,轴向阻尼、径向阻尼先增大后减小再增大。
