| Summary: | In order to guide and optimize structural design, this paper proposes a numerical simulation method for quickly predicting the mechanical test performance of marine electronic cabinets. According to the structural mechanics test standard of marine electronic equipment, the mechanical test simulation analysis of a type of marine electronic cabinet is carried out. Firstly, the finite element model of the electronic cabinet is established by ANSYS. Secondly, based on finite numerical solution method, the modal frequency, sine sweep vibration response, bumping response and shock response of the cabinet were obtained. Finally, according to the calculation results, the strength of the cabinet is checked, and the mechanical reliability of the cabinet is analyzed. The results show that the stresses near the right angles at the top and bottom, side boss and the right angles at the back are relatively high, but they are all lower than the maximum allowable stress of the cabinet, and the cabinet can work reliably under various test conditions. The modeling and analysis method presented in this paper can provide a good reference for the mechanical analysis of similar electronic equipment. |
