摘要
引信技术作为现代武器技术的重要组成部分,在国防领域得到广泛应用.引信运动试验台作为重要的地面设备,可以有效模拟引信的飞行运动,提高引信的分析测试效果.基于引信运动和攻角方程的理论,分析其二圆运动,研究引信的分运动及运动合成,完成引信运动试验台的结构设计和模型建立.结合动力学仿真,生成运动轨迹图,并求解连接部分所受扭矩范围.对连接部件进行有限元强度分析,得出连接部分的最大变形量为0.003 8 mm,最大应力为179.72 MPa.最后按照试验台模型研制实物,采用正交试验验证试验台在极限情况下的可靠度可以达到95.54％,完成引信运动试验台分析制造全过程.
Abstract
As an important component of the modern weapon technology,the fuze technology is widely used in the field of national defense.The fuze motion test-bed,as an important ground equipment,can effectively simulate the fuze's flight motion and ensure better effects in analysis and test.In this article,the fuze's bi-circular motion is analyzed based on the theory of the fuze's motion and the angle of attack equation;the fuze's sub-motion and motion synthesis are explored,the structure design of the fuze motion test-bed is conducted and its model is set up.The motion trajectory is formed in combination with dynamic simula-tion;the torque range of the connecting part is solved.The finite-element strength analysis of the connecting part shows that the maximum deformation of the connecting part is 0.003 8 mm and the maximum stress is 179.72 MPa.Finally,the physical test-bed is developed according to the model;orthogonal test shows that the test-bed's reliability reaches 95.54％under the limit con-dition.So far,the whole process from analysis to manufacture of the fuze motion test-bed has been completed.
