Abstract

The overload of the existing high g value impact test device is generally lower than 50,000g. To solve this problem, an experimental method is proposed to make the impact part obtain a higher overload than the traditional device through a simple method by using a high-speed turntable. In this method, the motor drives the turntable to rotate, and the impact head is placed at the edge of the turntable. When the rotating speed of the turntable reaches the threshold, the steel plate is pushed forward, and the impact part obtains the speed and impinges the impacted part. The finite element simulation model of the main structure of the test device was established based on ANSYS /LS-DYNA. The simulation took the mass of the impacted part material and the impact head as the experimental variable, studied the influence of the experimental variable on the magnitude of overload through the control variable, and recorded the maximum acceleration that could be achieved under each variable. The results show that the overload of the high overload test device in the form of a turntable can exceed 80,000-90,000g, and the device can be used as a test device for experiments with high overload requirements.
