摘要
为研究支撑方式对发射系统动态特性的影响,对某多管火箭炮支撑方式进行分析。采用ADAMS和ANSYS软件,在ADAMS中建立刚柔耦合模型,利用虚拟样机技术分别对半刚性支撑和轮胎支撑2种方式进行发射动力学仿真分析,研究2种支撑方式下定向管管口的振动规律,并对其起始扰动计算结果进行比较。分析结果表明,半刚性支撑发射方式优于轮胎支撑发射方式。
For researching on influence of different supporting way on dynamic characteristics of launch system, analyze certain type multiply launch rocket system supporting way. Use ANSYS and ADAMS software, establish coupled rigid and flexible model in ADAMS, use virtual prototype technology to carry out launch dynamic simulation analysis for semi-rigid support and tire support. Research on vibration rule direction pipe orifice in 2 supporting ways, and compare the initial disturbance results in 2 supporting ways. The result indicated： semi-rigid support is better than tire support.
