以求解广义动力学方程为基础，分析了飞机在外挂物弹射投放时所引起的动载荷问题，实现了用直接矩阵提取方法（ＤＭＡＰ）计算外挂物连续投放动载荷；用半机模型计算全机外挂物非对称投放动载荷；以及未投放外挂物的多自由度动载荷计算问题。计算结果表明，该方法能有效地解决飞机的各种动载荷问题。
Based on solving the generalized dynamic equations, the dynamic load problem caused by the projectile throwing of aircraft is analyzed, and the direct loading matrix (DMAP) The non-symmetric dynamic loading of the plug-in load; and the calculation of the dynamic load of multiple degrees of freedom without the plug-in load. The calculation results show that this method can effectively solve various dynamic load problems of aircraft.
