某弹性支撑导弹发射装置动力学特性的研究

The Study on Dynamics Characteristics of Missile Launcher with Flexible Support

为研究某车载导弹发射装置采用轮胎直接着地支撑时的动力学特性,通过UG和ANSYS软件,在ADAMS中建立导弹发射装置的整车虚拟样机模型;通过ADAMS对建立的虚拟样机模型进行模态分析,得到发射装置的模态参数及导弹发射装置高低角的增加对发射装置模态参数的影响规律;对导弹发射过程进行仿真分析,得出导弹发射过程中整车响应情况,以及不同发射角度对导弹出筒时姿态角及角速度的影响,分析结果可为发射系统指标提出及参数选取提供依据。

In order to study the dynamic characteristics of a vehicular missile launcher with flexible support, the fictitious prototype model of the vehicular missile launcher was established in ADAMS by the software of UG and ANSYS. The launcher＇ s natural frequencies and mode shape and the influence rules of altitude angles were obtained by modal analysis in ADAMS. Then the response of the vehicle and the influ- ence of missile＇ s angle and angle velocity for different launching angles during launching were studied hy simulation. The results could pro- vide a basis for specifications of launching system and parameter selection.
