| Abstract: | According to the actual working conditions of the key components of the drum brake,the corresponding modal analysis of the brake base plate,brake shoe and other components of the drum brake is realized,the last eight modes are selected respectively,and the corresponding vibration modes are summarized.From the vibration mode diagram and the summarized analysis list,the modal analysis results of the main components of the drum brake and the resonance evaluation reaching the natural frequency are obtained,which provides a certain side reference for the structural strength analysis of drum brake in the design stage,and has practical engineering significance. |
