| Abstract: | According to the vibration test standard of the electronic equipment structure, a finite element model of converter cabinet is built by ANSYS. The modal frequency of structure and the structural response under shock loading are obtained. Compared with the test results, the reliability of finite element model of converter cabinet is verified. The vibration characteristics of converter cabinet are analyzed. The results show that there is larger shock energy on the top of the inverter cabinet and smaller inside. The equipment in the cabinet can be effectively protected. |
