From the damage cloud map, fatigue damage is easy to occur near 2 fixed mounting feet, the most serious damage area near the installation foot without reinforced hamstring characteristics, away from the installation foot quality is more concentrated near the magnet damage is minimalStructural resonance is a comprehensive balance between external forces and structural inertial forces, elastic forces and damping forces under the dynamic external load. It is characterized by modal inertial and damping forces in the structure. The focus of preventing vibration fatigue is mainly to reduce the level of structural vibration, especially local vibration level. According to the trend of modal vibration. The distribution characteristics of adding damping to local structures or applying other control techniques to influence the structure mode. For the sheet metal structure of the basin frame. Pure plane features need to be avoided. The flip-side grooves increase the characteristics of structural stiffness and vibration almanence, while paying attention to the elimination of defects in the material and the reduction of stress concentration
