| 摘 要： | 探讨了悬置道路模拟实验中频响函数的建立和路谱迭代方法。以某款轿车的发动机液压悬置为研究对象，在试验场采集了悬置的道路载荷谱。通过基于远程控制参数技术（RPC）对发动机悬置道路载荷谱进行了重构，重构的道路载荷谱达到了预期的精度要求。论述了建立悬置路谱模拟试验的总载荷序列的方法。应用文中的方法，在MTS831试验台架上对液压悬置进行了道路模拟耐久性试验，试验结果表明，所采用方法可成功用于悬置耐久性试验。

| Abstract: | A method determining frequency response function and road spectrum iteration steps for road simulation test was proposed and discussed here.The hydraulic engine mount(HEM) of a car was taken as a study objective,and the road spectrum exerted on the HEM was acquired in a proving ground.The road spectrum was reconstructed with a remote parameter control technology,and the results showed that the reconstructed road load agrees well with the original one.Also,the method determining the load block sequence was p... |
