Fuse Institutions Motion Simulation Test

The phenomenon of early burst(EB) and fuze dud of the co-relational fuze appear many times in the fire tests in our country. Due to be short of simulation testing and the testing method, the cause of EB and fuze dud is too hard to be exactly judged. The important base and foundation of the fuze design, develop, failure analysis and performance evaluation is the movement law of the fuze mechanism in the ballistic environment. The fuze mechanism which usually has the small bulk and light mass go through the complicated ballistic environment featured high velocity, short time, tempestuousness change. The movement law of the fuze mechanism is too hard to be directly obtained by the fire test in the ballistic environment so far. To reappear the movement law of the fuze mechanism in the ballistic environment by possibly approaching physical simulation becomes a goal of developing the fuze techniques in the world.The three degree of freedom of the projectile is realized by the mechanical means on the high angle velocity gyro simulator. The three electromotor supported by the bracket of the gyro is the drivers of the three degree of freedom. The tests fuze is fixed on the axes of the rotation of the simulator. The angle movement law of the projectile and the influence on the angle movement of the fuze are reappeared by changing the radius of the fast circularity and the slow circularity and controlling the rotate velocity of the driving electromotor. The requirement of super high rotate velocity what the angle movement of the projectile needs to simulate circumrotate can be satisfied by the high angle velocity gyro simulator. The high angle velocity gyro simulator is the movement simulation platform to design the fuze mechanism and analysis failure and can simulate and test the rotation, notation and precession.The movement simulation and testing system of the fuze mechanism used on the high angle velocity gyro simulator is designed in this paper by developing the principium and the testing techniques of the gyro high velocity simulator. The control system program of the high angle velocity gyro simulator is designed by using the modern alternating current speed regulating techniques and serial transmission techniques, has featured with high response speed, precision control and stable control, can simulate truly the ballistic environment, and the control system program avoid contact directly frequency changer by using human computer interactive interface to control the high angle velocity gyro simulator, develop the safety and reliability of the system manipulation. Because of the fuze mechanism featured with small bulk, many parts and light mass the testing system use non-contact measurement techniques. The fuze testing system program of the high angle velocity gyro simulator is designed by LabVIEW language used on the testing and control system. The fuze testing program can gather data, process data, memory data, review data and simulate and test the rotation, notation and precession of the fuze mechanism with the projectile. The operational characteristics of the entire movement simulation and testing system of the fuze mechanism are developed by combining the movement simulation control program with the testing system program. The movement law of the rotation, notation and precession of the fuze mechanism is obtained when the dynamic characteristics of the fuze mechanism are not influenced. The movement simulation and testing system of the fuze mechanism is functional, high reliability and precision by testing. The theory of the fuze dynamic design and failure analysis is offered.
