为解决通用发射系统因适装武器长度差异而导致的换弹低效问题,提出了一种可调发射基座,该基座可实现舰基座之上两态高度调节与自锁。以可调基座升降系统为研究对象,基于刚柔耦合计算方法,运用ADAMS虚拟样机技术建立其刚柔耦合动力学模型,仿真分析了该升降系统在舰船摇荡作用下的运动学和动力学特性,并得出系统中关键构件的模态振型和工作过程中的应力应变情况,基于Pro/E平台完成三维建模与虚拟装配。仿真结果为可调基座的动力学结构和相关参数的改进和优化提供了模型基础和数据支撑。

In order to solve the problem of the poor convenience of ammunition replacement caused by the difference in the length of suitable weapons in the general launch system,an adjustable launch base is proposed,which can realize the two state height adjustment and self-locking on the ship base,and complete the 3D modeling and virtual assembly based on the Pro/E platform;Taking the adjustable base lifting system as the research object,based on the rigid flexible coupling calculation method,the rigid flexible coupling dynamic model of the lifting system is established by using ADAMS virtual prototype technology.The kinematics and dynamic characteristics of the lifting system under the action of ship swaying are simulated and analyzed,and the mode shapes of the key components in the system and the stress and strain conditions in the working process are obtained.The simulation results provide the model basis and data support for the improvement and optimization of the dynamic structure and related parameters of the adjustable base.
