某集装箱式火箭武器发射系统的非线性有限元建模与仿真

为了研究不同支撑方式对某集装箱式火箭武器发射系统的影响,基于非线性有限元法建立了其动力学模型;分别计算了发射系统在刚性支撑、弹性支撑和半刚性支撑三种工况下的动力学响应.结果显示了刚性支撑方式整体效果的优越性,为某特种集装箱式发射系统发射方案选择提供了依据.

Nonlinear Finite Element Modeling and Simulation of Container Pattern Launching System for Certain Rocket Weapon

In order to study the influence of different support methods on the container pattern launching system for a certain rocket weapon,its dynamics model based on the nonlinear finite element method is established.Dynamic response parameter of the launching system is calculated under the rigid bracing,the elastic support and the semi-rigid support of the entire launching system.Results show that the rigid bracing way is superior in the overall effect,and can provide the basis to select the launcher program of c...
