摘要
白车身模态参数是影响驾驶舒适性的重要指标,同时低阶弹性模态也反映了车身整体刚度性能。本文以某款皮卡白车身为对象,进行模态分析,以期获得白车身的200Hz以下模态的模态参数皮卡白车身的动态振动特性为避开共振频率,进行合理的结构设计提供依据。
The parameter of Body-in-white is an important index to control cab comfort, while the lower-order elastic modes also reflects the performance of the overall stiffness of the body. In this paper, a paragraph pickup object BIW, modal analysis, in order to obtain BIW 200HZ following modal modal parameters pickup BIW dynamic vibration characteristics provide the basis for avoiding the resonance frequency, reasonable structure design
