摘要

摘要: 针对气水缸活塞式鱼雷发射装置雷弹发射过程中气水缸冲击振动较大的现实问题, 对原紫铜垫缓冲结构进行改进设计, 提出采用紫铜垫与橡胶组合的新型缓冲形式。橡胶属于粘弹性材料, 以橡胶相关理论为基础,对其非线性特征进行分析, 建立了接触式的橡胶有限元简化模型, 分析了不同橡胶长度下橡胶应力、变形及接触反力情况, 并以功为评价指标与原缓冲效果进行了对比。仿真结果表明, 新型缓冲机构缓冲效果优于原缓冲机构,综合考虑, 选择橡胶长度为27 mm时缓冲效果较为理想。

Abstract: Considering the serious impact and vibration of a gas-water cylinder during launching process of a torpedo or a missile by torpedo launcher, a new type of rubber buffer mechanism is designed with combination of copper cushion and rubber to improve the existing copper cushion buffer mechanism. Because rubber is a viscoelastic material, the rubber related theory is used to analyze the nonlinear characteristics of the rubber, and a contact-type rubber finite element model is established. The stress, deformation and contact reaction force of the rubber with different lengths are analyzed, and its buffering effect is compared with that of the existing copper cushion by taking work as the evaluation index. The simulation results show that the new buffer mechanism is better than old one, and the buffering effect is optimum when rubber length is 27 mm under certain conditions.
