Abstract

An impact testing device and an experimental method based on a space-moving sandwich plate structure, relating to an impact testing device and an experimental method. The invention solves the problem that the impact test of the existing fixing device cannot be used for the test simulation of the impact response behavior of the composite sandwich plate structure in a moving state. The horizontal plane moving device of the present invention is plugged on the experimental base, the vertical plane vibrating device is plugged on the horizontal plane moving device, the upper mounting splint and the lower mounting splint are buckled and the composite sandwich plate is clamped and installed on the vertical plane vibrating device . In the present invention, the impact signal excitation device guides the falling movement of the hammer head; the signal generating device and the signal receiving device measure the height and falling speed information corresponding to different positions of the impact hammer head at the time of falling. The invention is used for testing mechanical properties.

Description

Technical field [0001] The present invention relates to an impact test apparatus and an experimental method, and more particularly to an impact test apparatus and an experimental method based on a spatial motion clipboard structure. Background technique [0002] Composite sandwich board, or a sandwich clamping plate is a typical interlayer suction structure, which has a key role such as damage to the protection target to collision, impact, and improve the protection of the structure. The composite sandwich plate is mainly made of a panel prepared by a metal material or a non-metallic material, and a resistance material between the panels. Typically, the impact test for the composite clamp board is completed on the fixed device, i.e., mounted the test structure on a fixed experimental device, and then performs the corresponding impact test by impacting the device. [0003] In many engineering applications, a composite sandwich board as an important protection approach is often acc...
