摘　　要：本文通过对比将导流器与发射车作为一个整体进行受力分析和将导流器与发射车作为铰接关系进行受力分析的理论载荷传递路径,发现将导流器与发射车作为铰接关系进行受力分析时为保证发射稳定所需的导流器底座与地面摩擦系数更大,进一步采用仿真建模的方式验证了理论载荷传递路径的正确性,并通过整车发射动力学仿真分析得到了不同导流器底座与地面摩擦系数条件下发射过程中导弹的姿态变化规律,为指导车载垂直热发射单面导流器传载设计和发射车发射场坪的选择提供了有力支撑。By comparing the load transfer path of the single-faced deflector as a whole with the vehicle and as a part which is hinged to the vehicle, the friction coefficient between the bottom of single-faced deflector and the ground is found to be much larger if the single-faced deflector is treated as a part which is hinged to the vehicle to guarantee the stability of the launcher. In order to validate the load transfer path of single-faced deflector, several simulations are carried out. And the missile’s attitude during launching on different friction coefficient between the bottom of single-faced deflector and the ground is acquired with vehicle launch dynamic simulation, which can be powerful support for the design of the single-faced deflector on vehicle-mounted vertical thermal launcher and the selection of the vehicle launching environment.
