Aiming at the heeling condition problem of ship control cabinet in environment, carry out finite element mechanics simulation for control cabinet frame. Put displacement fully constraint on damper, the control cabinet was simulated with a 45 degree roll environment, the impact of lateral 2 g and vertical 1 g acceleration is applied simultaneously, and verified by calculation. The results show that the maximum stress is on the shock absorber base bolt. The size is 191.2 MPa, which is lower than the allowable stress of the material by 235 MPa. It meets the design requirements. Through the theoretical analysis, the design risk is reduced, and the design of the later period is reduced, so the design cost can be cut down. It provides a theoretical basis for the design of the product.
