Abstract:	The axis calibration equipment is used to verify the consistency between the axis spacing size of antiaircraft weapon and the theoretical design size, and its performance has a significant impact on the fire strike accuracy of antiaircraft weapon. A self propelled antiaircraft weapon has the characteristics of a wide range of axis systems and large axis spacing dimensions, and the existing equipment cannot meet its axis calibration requirements. Therefore, a new type of axis calibration equipment configuration is proposed based on the configuration of the main support plate and the connection structure. The overall finite element calculation model of the system is established for the axis calibration equipment, and the statics, buckling and vibration modal simulation analysis is carried out based on the force conditions under the real use scenario, and the mechanical characteristics of the axis calibration equipment are obtained. The new type of axis calibration equipment has good stiffness and strength characteristics under usage conditions, good stability performance of equipment configuration, and can avoid vibration damage in transportation environment, meet the needs of axis calibration. It has certain reference significance for the configuration design and mechanical analysis of axis calibration equipment.
