A movable damping adjustable double pendulum impact testing machine

Abstract

The present invention discloses a movable damping-adjustable double-swing rod impact tester, which comprises a host machine rack, a base, a double swing rod system, a lifting system, a braking system, an angle adjusting device, a damping adjusting device and a measurement system, wherein the bottom portion of the base is provided with foot seats and rolling wheels, the rolling wheel is provided with a locking device, and the damping adjusting device is arranged between the upper swing rod and the lower swing rod, such that the swing rod system impacts with different acting force are achieved by adjusting different damping coefficients. According to the movable damping-adjustable double-swing rod impact tester of the present invention, the stepless adjustment on the impact angle and the instantaneous two-way performance testing are achieved by adopting the double-swing rod structure, and the impact tests with different acting force are achieved by adopting the damping adjusting structure of the tester; and the rolling wheels and the foot seats are arranged on the base, such that the movable damping-adjustable double-swing rod impact tester can be fixed or can move.

Description

technical field [0001] The invention relates to a movable damping adjustable double pendulum impact testing machine. Background technique [0002] The damping adjustable double pendulum impact testing machine is a new equipment specially developed for the bidirectional performance test of the surface of the test plate under the instantaneous load. The main function of the device is to measure the anti-destructive strength of the test plate under the action of transient high-speed impact, and to realize the impact of different force by adjusting the damping coefficient, so as to effectively judge whether the test plate is qualified, and to carry out the performance enhancement test after the test plate is qualified. . [0003] The damper undertakes the task of buffering and vibration reduction. The larger the damping force, the smaller the jumping height of the down swing bar, resulting in a larger impact load; the smaller the damping force, the larger the jumping height of ...

AI Technical Summary

Problems solved by technology

[0005] The existing single pendulum testing machine has a single degree of freedom and cannot perform instantaneous and two-way impact tests on the test board; the impact test performed by the traditional weight drop test machine only tilts the test board at a certain angle to the drop weight. direction, but although this test method can obtain the energy value absorbed by the test board in both horizontal and vertical directions, the impact time is not instantaneous

Moreover, most of them directly fix the testing machine on the foundation, which consumes a lot of engineering when moving.
