汽车悬置质量转动惯量的试验测定

Measurement of the Mass Rotational Inertia Momentum for Automotives

汽车悬置质量转动惯量是研究汽车性能最基本的参数,测定汽车悬置质量、质心位置和转动惯量等参数是一项最基础的研究工作,目前测定转动惯量的方法是通过测定汽车在摆动平台上的摆动周期来确定的,需要投资较大的实验设备。本文介绍了以测量汽车前后偏频和角振动周期为基础的纵向和横向转动惯量的测试方法和测试结果,本文提出的测量方法,省去了较贵的专用实验设备,具有测试仪器的一般工厂都可测量汽车的转动惯量。

Based on the measurement for frequency deviation and period of angular vibration of automotives, a method and results for measuring the axial and traverse rotational inertia momentum have been introduced.By this method, the rotational inertia momentum can be measured, even without special, sophisticated equipments.
