摘　　要：目的研究弹丸章动对引信S&A时间的影响。方法基于多刚体动力学及外弹道飞行理论,建立章动作用下引信安全与S&A延期解除隔离时间的数学模型。通过ADAMS仿真得到不同章动力矩对引信S&A延期解除隔离时间关系曲线。结果弹丸章动运动使得水平转子的合力矩增大,章动与引信S&A延期解除隔离时间成反比。弹丸出炮口速度为450m/s,章动力为0.35N时,S&A延期解除隔离时间为65ms,与其他文献的延期解除隔离时间69ms相差6%。结论本文所建立的S&A数学模型准确性较高,可为引信精准解除隔离、分析膛炸问题提供理论依据。The work aims to study the effect of projectile nutation on the S&A time of fuze.A mathematical model for the delayed arming time of the fuze S&A under nutation motion was established based on the multi rigid body dynamics and the external ballistic flight theory.The relationship curve between different nutation torques and the delayed arming time of the fuze S&A was obtained through ADAMS simulation.The results showed that the nutation motion made the combined moment of the horizontal rotor increase,and the nutation motion was inversely related to the delayed arming time.The velocity of the projectile out of the muzzle was 450 m/s,the nutation force was 0.35 N,and the delayed arming time was 65 ms,which was 6%different from the delay arming time of 69 ms in other reference.This result verifies that the S&A mathematical model established in this paper has high accuracy,and can provide a theoretical basis for accurately arming fuze and analyzing chamber explosion prob-lems.
