随着科技的不断发展,汽车行业中模态分析与试验技术的应用越来越广泛,是汽车零部件甚至是整车的动态特性分析的前提和基础。文章针对某商用汽车的转向系统进行了分析,对其振动激励源以及传递路径特性进行了研究,通过方向盘、转向柱等组件的模态测试获取了相关参数,为动态特性的分析和优化提供有效的依据。
With the continuous development of science and technology, the application of modal analysis and test technology in the automobile industry is more and more widely. It is the precondition and foundation of the dynamic characteristics analysis of automobile components and even the whole vehicle. In this paper, the steering system of a commercial vehicle is analyzed and its vibration excitation source and transmission path characteristics are studied. The relevant parameters are obtained through the modal test of the steering wheel and steering column, which provides effective analysis and optimization of dynamic characteristics The basis.
