冲击载荷下某发射装置动态特性分析及优化
Analysis and Optimization of Dynamic Characteristics of a Launcher Under Impact Load
为保证载具的稳定性和可靠性，针对某载具发射装置开展强激励下的动态响应分析。建立土壤-混凝土-载具结构的有限元模型，通过MATLAB和ABAQUS联合开发对模型的土壤边界批量施加黏弹性边界和地震动集中力载荷，对地表以CONWEP加载方式施加爆炸载荷，分别分析载具受到地震和爆炸载荷作用时的动态响应。结果表明，受地震和爆炸时装置的响应分别以水平和垂直方向为主，载具的垂直位移峰值均高于水平峰值但没有碰撞风险，载具倾角峰值均小于1°。结合麻雀搜索算法（SS…查看全部>>
In order to ensure the stability and reliability of a carrier, the dynamic response analysis of a launcher under strong excitation was analyzed. The finite element model of soil-concrete-carrier structure was established, and the viscoelastic boundary and seismic con-centrated force loads were applied in batch to the soil boundary of the model through the joint development of MATLAB and ABAQUS. The explosive strong excitation load is applied to the surface i…查看全部>>
