Abstract

The electromotor shell is analyzed by the finite element method. The result shows that vibrations of exterior and the top of the shell produce the shell vibration. The rib reinforcement type and the surrounded structure are designed to optimize and ameliorate the prototype structure. Then vibration and noise are analyzed. From the results it can be seen that amplitude at the top in the rib reinforcement type is suppressed effectively, while amplitude in the exterior is large. The surrounded layer in the surrounded structure successfully breaks the bridge of the inner cylinder to the outer cylinder. Then the vibration of electromotor is absorbed by the surrounded layer and the vibration reduces obviously. The acoustic field mean of the surrounded layer is lowest in the three structures, which effectively reduces the radiated noise from the top of the electromotor shell.
