摘要:
根据某舰炮摆弹机构的摆弹时间与结构强度的设计要求,对摆弹机构进行了动态设计。利用摆弹机构的刚体动力学方程,获得了机构的初始设计参数;利用有限元法,得到了摆臂的Craig-Bampton模态,建立了将摆臂作柔体处理的机构动力学方程,获得了摆臂的动态应力时间历程以及在停止位置的弹药振动响应;通过对不同弹簧刚度、不同弹簧预压力、不同摆臂厚度情况下计算结果的比较分析,得到了一组满足设计要求的较佳设计参数。所采用的机构动态设计方法可提高机构设计的可靠性和准确性,为工程设计提供了依据。
Abstract:
According to the design requirements of swing-up time and structure strength of the ammunition swing device of a naval gun,a dynamic design process is conducted here.Through solving the rigid dynamic equations of the device,the initial design parameters are obtained.The Craig-Bampton modes are solved using the Finite Element Method,and the dynamic equations of the mechanism system considering the swing arm to be a flexible body are built.By solving the multi-body dynamic equations,the time response history of dynamic stress of the swing arm and the vibration response of the ammunition at stop position are obtained.The simulation results for different spring stiffness,different spring preload,and different swing arm thickness are compared.According to the computation data,one group of design parameters satisfying the given design requirements are obtained.The dynamic design method can improve the reliability and accuracy of the device in design and this design result can provide reference for practical engineering design.
