摘要
前后舱盖模态可用于评价前后舱盖总成结构的固有频率及振动形式是否合理,能否满足实际使用要求,以便为基于前后舱盖动态特性的设计开发提供参考依据。通过以海马某型轿车作为样本,在相同位置截取前舱盖和后舱盖,利用有限元法对总成结构进行了自由模态分析,考察了前后舱盖固有特性是否满足设计要求。
The modal analysis of the engine hood and the rear baggage cover is to evaluate whether the natural trequency and me vibrauon type of the structure is reasonable to satisfy the requirement in practice or not, in order to provide a reference in the design based upon the dynamic characteristic. Taking one vehicle model of TJI as a sample, the modal analysis of the engine hood and the rear baggage cover is performed by FEM.
