某导弹折叠弹翼展开过程的仿真分析

Simulation Analysis of a Missile Folding Wing Deployment Process

折叠弹翼的展开性能关系着导弹发射后能否正常飞行。以某导弹的折叠弹翼为研究对象,对其展开过程进行仿真分析。根据其结构和工作原理,在Adams多体动力学软件中建立仿真模型,仿真其在不同作动力曲线下的展开过程,得到弹翼展开角度、角速度、动能曲线和弹翼与锁定销之间的碰撞力曲线,并对弹翼展开过程中的性能进行检验。仿真结果表明:弹翼能迅速展开到位,并能准确定位、可靠锁定,展开过程中各部件之间不会相互干涉。

The deployment performance of folding wing has relation to the normal flight of missile. A certain type missile folding wing is studied, and the deployment process is simulated. According to its structure and working principle,build simulation model in Adams. Simulate the deployment process under different driving forces, and get the folding wing＇s angle, angular velocity, and kinetic energy curve, and the impact force curve between folding wing and the locking pin. Estimate the performance of deployment process. Simulation results show that the folding wing can unfurl to the appointed place quickly, can be located accurately and locked reliably, and there is no interference between each parts during the deployment process.
