Ice replacement type collision testing machine

Abstract

The invention discloses an ice replacement type collision testing machine which comprises a stander, a hydraulic cylinder and a pipeline, wherein the hydraulic cylinder and the pipeline are fixedly mounted on the stander; a push rod of the hydraulic cylinder extends into the pipeline; a collision head is arranged on the top of the end, which extends into the pipeline, of the push rod; a leather collision pad is mounted on the collision head; a material outlet is formed in the front end of the pipeline; a material inlet is formed in the side wall of the middle of the pipeline and is opened and closed through a dividing plate; a pressure sensor is arranged in the pipeline under the material inlet; the position of the collision is higher than the position of the pressure sensor. The material inlet controlled by the dividing plate is formed in the side wall of the pipeline, and the pressure sensor is arranged in the pipeline under the material inlet; the hydraulic cylinder controls the push rod to collide with an ice ball falling from the material inlet, so that the ice ball can get out of the material outlet of the pipeline and collide with a material to be tested; the material to be tested is continuously collided, and the collision speeds are adjusted in real time; by virtue of statistical analysis on the times, the speeds, the frequency and the depth of the collisions, the collision characteristic of the material to be tested is determined.

Description

technical field [0001] The invention relates to an ice-changing collision testing machine, which belongs to the technical field of mechanical engineering. Background technique [0002] Nowadays, due to the needs of the working environment, many engineering equipment are mostly installed outdoors. While ensuring the normal operation of the manufacturer, they also need to have sufficient strength to resist a certain degree of natural damage. This requires that the equipment should not have excessive economic investment. At the same time, sufficient surface mechanical strength is also required. Based on this, various testing machines for material performance testing continue to appear. However, there are many types of collisions. It is difficult for conventional testing devices to connect all conditions. The conditions that may meet the required special conditions are simulated. Contents of the invention [0003] In view of the above technical problems, the purpose of the pr...
