Structural design and analysis of fuze motion test-bed
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.
