Large Pulse Width, High Amplitude Shock Process Simulation Method And Test Device

In the modern war, the penetration ammunition weapons have become the focus of countries. Penetration fuze, as the core of the ammunitions of the safety and explode-control systems, play a vital role. Penetration process is a transient, high-energy, high-impact process. In such a harsh environment, fuze could be able to be damaged; especially the thin-walled parts of the structure, fuze power and the circuit board, resulting in fuse failure. To ensure the reliability of the fuse in the high acceleration environments, the samples must be conducted the anti-overload test in the development stage.For simulating the high-overload environment during penetrating, the basic theory of shock and vibration, and the rules and the answers of shock and vibration simulation have been studied. A variety of test equipments have been researched, the program using the test vertical machine with the energy-storage spring has been proposed for obtaining the pulse width and high-amplitude shock. And every component have been calculated and designed.According the design, the three-dimensional models of the impact-tested machine have been created using SolidWorks. And using the limit element simulation software Ansys and the dynamic simulation software Adams, the collision process has been simulated. Analyzing the results, the design has been tested.Based on the working process of the test machine, the control system using PLC has been designed, the ladder-shaped diagram has been drawn. The acceleration-tested system is designed, including the selection of the types of the sensor and the design of the conditioning circuit. Using the Maxi Te hammer test system, the acceleration-tested system has been experimented, and the correctness of the design has been tested.
