摘要
汽车结构模态分析在工程振动中占有重要地位,利用有限元方法对车架进行模态分析,获得车架模态参数-频率、振型等,对存在的问题提出一些改进措施,使得车架结构尽量避免产生共振和噪声,增强了汽车稳定性、舒适性和安全性,同时也为实际试验提供了参考和依据。
It is important for dynamic of vehicle with modal analysis in mechanical engineering, modal analysis is applied to vehicle frame with the Finite Element Method, modal parameter（frequency,vi- bration characteristic）far the response analysis is computed. According to these results,some ameliorative advice will be put forward,and the results are significant for vehicle frame to avoid vibration and noise, stability,comfortability,.security will be strengthen for the automobile,and the results can be supplied as reference for the practical test.
