Abstract:	Artillery seat is an important part to support the turret, transmit the firing load and execute the rotation. The performance of artillery seat has an important influence on maintaining the stability of the artillery and ensuring the shooting accuracy. In order to achieve the design requirements of lightweight, flexible rotation, high reliability and good stability of artillery seat, the mathematical model of influence of artillery seat mass, backlash and turning moment on artillery seat performance was established in this paper. And using weighted coefficient method and artificial intelligent optimization algorithm, the multi objective optimization design of lightweight and flexible rotation of the artillery seat was realized with four key design parameters, namely ball radius, raceway radius, ball center position and contact angle, and the final optimization result was obtained. It was found that the mass of the artillery seat was reduced by 1.7%, the turning resistance was reduced by 14.1%, and the clearance was reduced by 41.5%. The optimization design method studied in this paper has a certain theoretical guiding effect on the design and optimization of artillery seat.
