Modal Analysis for Torque Converter Based on ANSYS

The wheels of the torque converter modes were analyzed by using FEM software ANSYS Workbench,the models natural frequency of each rank and their corresponding vibration modes were gained.The effects of structure,stress stiffness and spin softening on the wheels’natural frequency while torque converter in real operation condition were also analyzed at the same time.The resonance frequency was gained under the working speed,which will sever as an optimal design basis for some type of torque converter.
