The electromechanical control cabinet of surface ship rudder is an important component of the rudder system. Its shock resistance ability directly affects the maneuverability, vitality and safety of the ship. Using the numerical simulation DDAM method to verify the shock resistance ability of the electric control cabinet is clear and efficient, which is the main design method of the ship equipment. With the help of ANSYS Workbench software, the finite element analysis model of the whole electric control cabinet composed of cabinet, drive-shell, water-cooled plate, water-cooled resistor, DC-link capacitor and vibration isolator was established by using bar element, spring element and tetrahedron element. According to the requirements of shock resistance assessment, the dynamic design DDAM method is adopted. First, the structural modal analysis is carried out to extract the modal frequency and corresponding modal mass of each stage, then the acceleration and velocity are calculated. Finally, the impact spectrum is drawn up and used as the input condition to analyze and view the impact dynamic response results. Summarize and calculate the maximum stress of each structure of the electric control cabinet The value of 359.99 MPa is smaller than the tensile strength of 520 MPa. The research results can provide some reference value for the evaluation and design of the impact resistance of electronic control equipment.
