摘要
根据火炮后坐的受力分析和动作过程,基于ADAMS软件建立了冲击头撞击炮口模拟火炮后坐的仿真模型,采用冲击质量、冲击速度、接触刚度及阻尼系数为试验设计影响因素,以模拟试验与实弹射击时火炮最大后坐速度和最大后坐位移的平均相对误差为试验指标,开展正交试验设计,并对正交试验设计结果进行方差分析,得到了较优的冲击参数优化组合,平均相对误差仅为0.6534%,该研究为模拟试验装置的应用奠定了基础。
Abstract： According to the gun power recoil force analysis and action process, gun recoil simulation model by the impact head hitting the muzzle based on the ADAMS software is established. Using the impact mass, impact velocity, contact stiffness and damping coefficients as the influencing factors of experimental design, and using the average relative error of the maximum recoil velocity and the maximal recoil displacement by comparing simulation test and real bullets as the test index, it is to carry out the orthogonal experimental design, and take a variance analysis of orthogonal test design results, which has obtained better impact parameter optimization whose average relative error is only 0.6534%. The study lays a foundation for application of the simulation test device.
