基于isight的某转管武器弹簧缓冲器优化设计

针对转管武器试验过程中出现的后坐阻力和后坐位移过大的问题,以某型转管自动机为研究对象,提出了一种基于isight的缓冲器优化设计方法.基于动力学分析软件ADAMS建立转管武器虚拟样机模型并对其计算结果进行分析.然后基于isight多学科优化技术,以最大后坐阻力作为目标函数,在后坐位移不超过19 mm的约束条件下采用最优拉丁超立方设计方法对缓冲簧设计参数进行灵敏度分析.利用isight集成ADAMS运行程序,采用多目标遗传算法NSGA-II对缓冲簧设计参数进行并行优化设计.实验结果表明:优化后的设计参数与最初方案相比其后坐阻力显著减小,同时该设计方法为转管武器缓冲器优化设计提供了参考依据.

Optimization Design of Certain Type Gatling Gun Weapon Buffer Spring Device Based on Isight

In view of the recoil force and recoil displacement were too large during tests of the gatling gun weapon, research on certain type gatling gun, and the method of the optimization design of buffer spring device based on isight is proposed. The gatling gun weapon virtual prototype model was built based on the dynamics analysis software ADAMS, and the results were analyzed. Then, the maximum recoil force is set as the target function based on the isight multidisciplinary optimization techniques, and carry on sensitivity analysis to the design parameters of the buffer spring by using the optimal design method of Latin hypercube under no more than 19 mm in recoil displacement constraints. The ADAMS running program is integrated with isight, the design parameters of buffer spring is carried out parallel optimization by using multi-target genetic algorithm NSCG-II. The results indicate that compared with the original scheme, recoil force of optimized design parameters decrease significantly, and the design method can provide a reliable reference basis for the optimization design of buffer spring device.
