摘要
为提高转管自动炮高速供弹机构的供弹运动可靠性,研究了高速供弹机构运动可靠性仿真方法,建立了某转管自动炮高速供弹机构的动力学仿真模型,采用随机抽样模拟拨弹轮的初始定位角误差,完成供弹机构的参数化驱动供弹仿真,结合可靠性应力强度干涉模型,计算了供弹机构的运动可靠性,并根据计算结果,比较和优化了设计方案。试验结果表明,通过运动可靠性仿真分析和优化设计,可明显提高高速供弹机构的运动可靠性,证明了高速供弹机构运动可靠性仿真方法的有效性,为高速供弹机构的运动可靠性分析提供了一种可行的方法。
In order to improve the motion reliability of high speed feed mechanism in high firing-rate whirling auto gun,the motion reliability simulation methods was studied,and a dynamic simulation model was established.The parametric driving simulation could be carried out by using random sampling to simulate the initial setting angle error of the transmission gear in the feed mechanism.Based on stress-strength interference model,the motion reliability of feed mechanism was calculated.Compared the calculation results,the design parameters were optimazed.The experiments show that the optimal feed mechanism can feed projectiles more reliably and the motion reliability simulation method is an effective method for the high speed feed mechanism.
