摘要
炮口强冲击是一种技术可行的火炮动力后坐模拟试验方法。为保证该模拟试验方法精度,基于ADAMS软件建立了火炮虚拟射击试验环境,以冲击质量、冲击速度、缓冲器的线性刚度等为试验因素,以火炮后坐动态特性的最大相对误差为试验指标;通过灵敏度分析得到各因素对模拟试验精度的影响程度,并应用GRG算法进行了优化设计。为火炮射击模拟试验装置的设计研究打下了基础。
The muzzlestrong impactis a feasible test method to simulate the dynamic recoil of gun firing process. In order to assure the precision of this simulative experiment method, the virtual testing environment was developed based on MSC. ADAMS platform. Taking impact mass, impact velocity, linear stiffness of buffer etc. as experimental factors, while maximum relative error of firing dynamic response were regarded as experimental index, the influence degree of various factors on the precision of simulative experiment wasobtained by means of sensitivity analysis, and impact parameters were optimized based on GRG algorithm. The research can provide a reliable basis for the design of gun firing simulator.
