摘要
针对现有收放机构无法应用于小型智能弹药的现状,设计了旋转折叠舵面收放机构,满足了智能弹药小型化的需求.通过对舵面展开运动的分析,设计了舵面收放机构;运用UG-NX6软件建立了舵面收放机构的三维模型,导入ADAMS软件中建立了虚拟样机并进行了动力学仿真,分析了影响舵面展开的主要因素,获得了优化后的设计参数.仿真结果表明:机构运动可靠,对弹体冲击载荷小,优化后展开到位的总时间为375.5 ms,满足智能弹药折叠舵面设计要求.舵面折叠后弹药的整体直径为63 mm,有效地实现了智能弹药小型化的需求.
In view of the current situation which the existing retracting mechanism for rubber cannot be ap- plied to small intelligent munitions, a rotating-folding retracting mechanism for rubber was designed, in order to satisfy the requirement of small intelligent munitions. The rubber retracting mechanism was designed based on the analysis of the rudder movement. A 3D mode of the rubber retracting mechanism was built by UG- NX6 software, which was imported into ADAMS to get a virtual retracting mechanism for dynamics simula- tion. The main factors that affect the dynamics of the retracting mechanism were analyzed to obtain optimized design parameters. The simulation results show that the movement of mechanism is reliable, quick and accu- rate, impact load on projectile body is small, and the total opening time is 375.5 ms after optimization, which satisfy the requirement of designing folding rubber for small intelligent munition. After folding, the overall di- ameter of rubber is 63 mm, that effective implementation of the smart intelligent munitions is achieved.
