Multifunctional double-swing rod impact tester

Abstract

The present invention discloses a multifunctional double-swing rod impact tester. According to the multifunctional double-swing rod impact tester, a removable swing rod position limitation mechanism is arranged on the host machine rack, a lifting system and a braking system are connected through a swing shaft and are arranged on the top end of the host machine top end, the upper swing rod is suspended on the middle of the swing shaft so as to achieve the lifting and the braking of the double-swing rod system, the upper swing rod and the lower swing rod form a hinged connection in the double-swing rod system, the lower end of the lower swing rod is connected with a pendulum, the hinged connection position of the upper swing rod and the lower swing rod is provided with an angle adjusting device, a buffer device is arranged between the upper swing rod and the lower swing rod, a measurement system is arranged on the base through a buffer pad, and a high speed sensor and a high speed data acquisition device are adopted to display the change curve of the force values in the horizontal direction and the vertical direction along with the time, the change of the variant feature point along with the time and the like through a computer during the impact process. The present invention provides the multifunctional double-swing rod impact tester with characteristics of high impact force, good buffer effect and safety on operators.

Description

[0001] technical field [0002] The invention relates to a multifunctional double pendulum impact testing machine. Background technique [0003] The double pendulum impact testing machine is a new equipment specially developed for the two-way performance measurement 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, which can effectively judge whether the test plate is qualified or not, and conduct performance strengthening tests after the test plate is qualified. The impact testing machine currently used has the following problems: the single pendulum system is used, the impact force is not large enough, the degree of freedom of the pendulum is low, and the instantaneous impact load cannot be grasped, only the impact energy can be grasped; the impact force generated by the regular impact test It will cause damage to the ...
