摘　　要：针对引信离心力驱动水平转子转动可靠性难以保证的问题,提出了离心力驱动引信水平转子质心优化方法。该方法是通过建立引信水平转子转正过程动力学方程,得到其质心回转半径与初始方位角的最优解关系式。仿真验证表明,初始方位角取值不同对引信水平转子动态运动特性影响较大,优化得到的最优质心回转半径及质心初始方位角能使得水平转子转动过程中的净驱动力矩值始终较大,从而有助于提高旋转弹引信水平转子转正正确性。For the problem that the centrifugal fuze horizontal rotor failled to rotate correcttly,an optimal de-sign on centroid position of horizontal rotor was put forward. This method set up kinetic equations of rotating of horizontal rotor to get the optimal relational expression of radius of gyration and initial azimuth. Simulation re-sults showed that the value of initial azimuth had a greater impact on dynamic motion characteristics of horizontal rotor. And the optimal radius of gyration and initial azimuth could make the value of net driving torque compara-tively larger during the rotation of horizontal rotor, which improved the rotating correctness of fuze horizontal rotor.
