摘要
为实现不同装填角度下弹丸的卡膛速度一致性和降低输弹运动的峰值功率,以提高输弹一致性和减轻动力系统负荷,根据惯性装填工作原理,运用非对称式S型速度规划方法调整输弹运动状态,并基于虚拟样机仿真建立了参数化的输弹运动模型.以弹丸的卡膛参数为约束,面向惯性装填建立输弹运动优化模型,以实现不同装填角度下弹丸的卡膛速度一致性及降低输弹峰值功率.采用多岛遗传算法和修正可行方向法组合优化策略求解优化模型,优化结果表明:优化后的输弹运动可实现不同装填角度下弹丸的卡膛速度一致性,且输弹运动峰值功率降低了14.9%,验证了该方法的有效性.
Abstract
According to the principle of inertial loading,a parameterized ammunition ramming motion model is established based on virtual prototyping technology,and the state of ammunition ramming motion is regulated by asymmetric S curve velocity planning method,so as to achieve the consistency of bayonet-chamber velocity under different loading angles and reduce the maximum power of ammunition ramming motion.With the parameters of bayonet-chamber as the constraint,a motion optimization model for inertial loading was established,so as to achieve the consistency of bayonet-chamber velocity and reduce the maximum power under different loading angles.Multi-island genetic algorithm and modified method of feasible directions are used to solve the optimization model.The optimization results show that the optimized ammunition ramming motion can achieve the consistency of bayonet-chamber velocity under different loading angles,and the maximum power of ammunition ramming motion is reduced by 14.9%,which verifies the effectiveness of the method.
