摘　　要：为提高引信离心球自毁机构自毁发火时的戳击能量进而保证可靠发火,提出引信离心球自毁机构作用动力学建模与仿真方法。该方法指出为确保自毁可靠性,可以通过锥角调整增大自毁发火能量,但因此而改变了自毁临界角速度,自毁时间发生了变化,为平衡这种变化,可通过调整自毁簧刚度系数以及离心球离心半径来实现。在保证自毁时间不变的情况下,通过理论分析并结合ADAMS仿真分析表明,自毁锥面在80°~100°范围内变化时,每增加1°,对应调整自毁簧刚度系数,自毁发火能量增大约11%,而对应调整离心球离心半径,自毁发火能量增大约0.13%。In order to increase the firing energy of fuze centrifugal self-destroying device to ensure reliability ignite,a kinetic modeling and simulation method of the fuze centrifugal self-destroying device was proposed.The method indicated thatthe angle adjustment could increase the firing energy to make sure the self-destroying reliability.But the critical angular velocity and the time of self-destroying were also changed.Adjusting the spring stiffness coefficient and the centrifugal radius could balance this change.The self-destroying time was ensured unchanged.The theoretical and simulation results showed that the method could make the self-destroying firing energy 0.13%increasing corresponding to the tapered cone angle 1°increasing when the tapered surface varied between 80°and 100°.
