| Abstract: | 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 structural design of cabinet for vehicle. |
