Problems solved by technology

[0002] When the high polymer porous elastic material is repeatedly impacted under constant load, the hardness of the test object will change when the test object is repeatedly impacted for a long time, which will cause the impact load to attenuate. The existing domestic instruments usually use manual observation of the change of the impact load to test the equipment. Manually adjust the compression impact distance to meet the standard requirements of the impact load. The test results of this method are greatly affected by man-made, and the test has to be interrupted during manual adjustment. It is difficult to adjust successfully at one time. The test data is often due to the adjustment of the tester to manually adjust the size of the impact load. , the number of times deviates from the original data; and the labor input cost is high
