Problems solved by technology
[0004] The existing single pendulum testing machine has a single degree of freedom, and cannot realize instantaneous and two-way impact tests on the test plate; the impact test performed by the traditional weight drop test machine just tilts the test plate 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

The invention discloses a damp-adjustable dual-oscillating-bar impact testing machine which comprises a main machine frame, a dual-oscillating bar system, a lifting system, a braking system, an angle regulating device, a damp adjustable device and a measuring system, wherein the lifting system is connected with the braking system through an oscillating shaft, the oscillating shaft is fixedly connected to the main machine frame, the dual-oscillating bar system comprises an upper oscillating bar, a lower oscillating bar and a pendulum bob, the dual-oscillating bar system is connected with the main machine frame through the oscillating shaft, the angle regulating device is arranged at a joint of the upper oscillating bar and the lower oscillating bar, and the damp adjustable device is arranged between the upper oscillating bar and the lower oscillating bar. By adopting the damp-adjustable dual-oscillating-bar impact testing machine disclosed by the invention, maximum impact speed, maximum impact load and maximum impact energy borne by a sample in a horizontal direction and a vertical direction can be obtained. The damp-adjustable dual-oscillating-bar impact testing machine is easy to operate, accurate in measurement, high in reliability, safe and stable, and convenient to maintain, and is especially suitable for testing a transient bidirectional impact load borne by the surface of a test plate.
Description
technical field [0001] The invention relates to an impact testing machine, in particular to an adjustable damping 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 this 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 conduct the performance strengthening 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 fo...
