摘要
建立了车载机柜系统的振动模型,得到频率比与传递率的关系,利用有限元NASTRAN软件对两种材料(铝合金和铁)车载机柜的固有频率和模态振型进行了计算,分析了机柜的动态特性,为车载机柜的结构设计提供了理论依据。
First a model of vibration was built for the cabinet for vehicle. It offered the relationship between the frequency ratio and the transm issibility. Then the inherent frequency and vibration model of the cabinet with two different materials （aluminium and iron） for vehicle were calculated by using the software of NASTRAN, and the dynamic characters were studied. Through the analysis this paper offer a theory foundation for the struetural design of cabinet for vehicle.
