In order to solve the problem of unclear dynamic response mode of inertial impact switch (IIS) under high-impact environments, a typical IIS was experimentally and numerically studied in this paper. In the test, the high-impact test system based on the Machete hammer device was built, and the system was applied to the hammer test of the switch, and the impact response signals of the switch were obtained. In the simulation, a full finite element model of the switch was established to simulate the impact process and analyzes its dynamic responses. The simulation and test results show a good agreement, suggesting that the method provided in this paper is reasonable and efficient, and offers a certain reference for the design of electromechanical ignition control system in fuse.

摘要

In order to solve the problem of unclear dynamic response mode of inertial impact switch (IIS) under high-impact environments, a typical IIS was experimentally and numerically studied in this paper. In the test, the high-impact test system based on the Machete hammer device was built, and the system was applied to the hammer test of the switch, and the impact response signals of the switch were obtained. In the simulation, a full finite element model of the switch was established to simulate the impact process and analyzes its dynamic responses. The simulation and test results show a good agreement, suggesting that the method provided in this paper is reasonable and efficient, and offers a certain reference for the design of electromechanical ignition control system in fuse.
