改装汽车的平顺性试验分析

Experiment and Analysis on Smooth-Going Perform anceof Some Modified Automobiles

对若干种型号的改装汽车进行了平顺性实际测试。计算与分析,其内容包括悬挂系统部分固有频率与相对阻尼系数的测定,在确定激励下汽车振动试验和路面随即激励下的平顺性试验等。本文通过数据处理与分析,讨论了共性问题产生的原因,提出了改进措施。

Experiments, calculation and analysis on the smooth-going performance of some modified automobiles have been carried out, which involves the measurement of natural frequency and relative damping coefficient of their suspension system, tests of smooth-going performance both under certain and random excilaling conditions. Based on data processing and analysing, this paper discusses some problems and proposes some means to solve them.
