Problems solved by technology
[0002] The existing single pendulum testing machine, single degree of freedom, cannot realize the instantaneous and two-way impact test of the sample; when the traditional drop weight testing machine performs the impact test, it just tilts the test sample at a certain angle to the direction of the drop weight, Although this test method can obtain the energy value absorbed by the test sample in both horizontal and vertical directions, the impact time is not instantaneous.

The invention relates to an impact testing machine, and more specifically relates to a shearing pin type double-pendulum rod impact testing machine. The shearing pin type double-pendulum rod impact testing machine comprises a main machine frame, a double-pendulum rod system, a lifting system, a braking system, a shearing pin type angle adjusting device and a pendulum shaft. The lifting system and the braking system are connected by the pendulum shaft; the lifting system, the braking system and the pendulum shaft are all arranged on the main machine frame; and the shearing pin type angle adjusting device is arranged in the double-pendulum system. According to the shearing pin type double-pendulum rod impact testing machine, the double-pendulum system is employed, and the angle between the two pendulum rods is adjusted by using the shearing pin, so that different impact loads are realized. In addition, the shearing pin breaks as soon as a sample is impacted by a pendulum bob, and then the two pendulum rods are at free states at the moment of impacting, so that double-way impact on the sample by the pendulum bob is realized, and the shearing pin type double-pendulum rod impact testing machine is especially suitable for experiments used for determining instantaneous double-way impact load of the surface of the sample.
Description
technical field [0001] The invention relates to an impact testing machine, in particular to a shear pin type double pendulum impact testing machine. Background technique [0002] The existing single pendulum testing machine, single degree of freedom, cannot realize the instantaneous and two-way impact test of the sample; when the traditional drop weight testing machine performs the impact test, it just tilts the test sample at a certain angle to the direction of the drop weight, Although this test method can obtain the energy value absorbed by the test sample in both horizontal and vertical directions, the impact time is not instantaneous. Therefore, it is of great significance to provide a shear pin type double pendulum impact testing machine that can measure the bidirectional properties of materials and ensure instantaneous impact. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a shear pin type double pendulum imp...
