Dynamic Simulation Analysis of the Base of Vertical Motor

In this paper, the models of the base of a type vertical motor were adopted to MSC. NASTRAN software to analysis modes and transient response, get transient response, natural frequencies and vibration shape based on element finite simulation, and the mechanics capability was proved, these main destroy forms and locations were gained. The effect of the vibration of the motor was also discussed according to these element finite simulation pictures and data. The results of element finite simulation of the motor related models showed that the structures of the motor base could meet the design requirement. Contrasted analyzes of vibration influence of different foot bolt to restrain the base were carried on. Dynamic Performances of the motor base were gained, which has the guiding sense in the vibrating test and optimizing design for the base of vertical motor.
