Application of constraint force equation method for missile launching dynamics modeling
-
摘要: 在传统的发射动力学微分方程基础上,添加了CFE(Constraint Force Equation)方法中的约束方程和自由度方程,建立了基于CFE方法的导弹发射动力学模型.以倾斜发射导弹系统为研究对象,定义了1个二自由度约束节点来描述导弹与发射架间的约束关系,通过建模计算得到了发射过程的约束力和约束力矩,最后利用软件ADAMS(Automatic Dynamic Analysis of Mechanical Systems)对该算例进行了计算,取得了一致的结果,从而验证了该方法在导弹发射动力学建模中应用的有效性,扩大了该方法的应用范围.Abstract: A missile launching dynamics model based on the constraint force equation (CFE) method was presented, by applying the constraint equations and joint degrees of freedom in traditional launching dynamics equations. An incline launching missile system was researched, the missile body and the launching device were connected by a joint of two degrees of freedom, constraint forces and moments in launching process were obtained by calculating the dynamics model. In the end the same case was calculated using software automatic dynamic analysis of mechanical systems(ADAMS), results were compared and analyzed with the CFE method, a good agreement is achieved, so the application of this method used for missile launching dynamics modeling is verified and the method-s application range is extended.
