关于汽车平顺性随机数据处理中几个问题的探讨

On Some Problems of Random Data Processing Relevant to Motor Vebicle Ride Vibration

对汽车平顺性随机数据处理中关于加速度功率谱密度函数与功率谱函数、以时间频率f与圆频率ω表示的功率谱密度函数等易于混淆的问题进行了阐述与推演。同时，还给出了在汽车平顺性测试中应用人体振动测试仪与传统测试系统所测结果的关系。

Problems easily to be mixed up in randon data processing relevant to motor vehicle ride vibration,such as acceleration power spectral density function, power spectral function and power spectral density function expressed in time frequency f and angular frequency ω,are expounded and deducted in the article. Meanwhile,relation between the results measured by means of vibration measuring dummy and conventional measuring system of motor vehicle ride vibration are given.
