摘要
推导了末敏弹二体运动模型计算中伞绳张力的表达式。先建立伞体和弹体各自的质心运动方程组，再由伞弹连接点是伞弹共同点这一约束出发，建立联系方程，最后求出伞绳张力，并将它代入未敏弹系统完整的运动方程组，联立求解。计算结果与试验实测结果有很好的一致性。
The expression for t he suspension line tension in a T arget Sensitivity Projectile (TSP) as a two-body model is derived, First, the respective centroid motion equations of the parachute and projectile are established. Connection equation is then derived from the constraint condition that the conjoint point of the parachute and projectile is the same point lying on the parachute and projectile, The expression for suspension line tension is thus given and leads into complete set of equations of motion of the TSP system. which are solved simultaneously . The computer resuits show an excellent agreement with the test results.
