摘要:
该文应用多体动力学对某高炮进行了减振研究 ,建立了考虑连发效应、动力响应和结构特性的高炮多体动力学模型 ,并采用带有操作指令的软件可仿真计算火炮系统的动态特性 ,结果表明 ,增加起落部分的转动惯量和改变炮身的凸肩位置可以显著地减小高炮连发射击时的炮身振动 ,这为提高高炮射击精度和指导结构设计提供了依据
Abstract:
Multi-body dynamics w ith its applicat ion in the vibrat ion reduct ion for antiaircraft gun is studied in this paper. The gun dynamic model is set up in w hich uninterrupted fire act ivit ies, dynamic response and constituent properties are considered. The dynamic properties of the gun system w hich are est imated f rom the sof tw are compiled f rom majority operat ions are simulated. T he results analyzed by numerical simulat ions show that the barrel. s vibrat ions caused by uninterrupted f ire are obv iously cut dow n by raising up the inert ia moment for recoi-l ing parts and alternating the location of the barrel prot rusion, w hich can reduce the gun tube muzzle disturbance. The conclusion is made to increase the gun fire accuracy and guide the gun st ructural design.
