The shock absorption tester for sports shoes uses software program and computer to operate and display. The test action process is as follows: place the sample sports shoes to be tested on the base and face the punch, and drive the ball screw to rotate through the software program-controlled servo motor at a constant speed. With the operation of the ball screw, the lifter drives the height adjustment block to rise to a predetermined height. The predetermined height is the height of the weight free falling impact sample sports shoes, At this time, the action of the air cylinder in the lifter is brought back to the clamp plate, the clamp plate is separated from the lower end of the height adjustment block, and the weight block falls freely to impact the sample sports shoes. The air cylinder in the lifter acts and the chuck resets. With the continuous operation of the ball screw, the heavy block is lifted again and the free fall impact is made. Such repeated impact is made for 30 times. For each impact, the displacement sensor obtains the displacement information of the weight, and the force sensor obtains the reaction force information. (The last five times of data are collected as the basis for determining the performance of the test piece) The above information can be transmitted to the computer to accurately test the damping characteristics of the sports shoes. It has the characteristics of high control accuracy, high measurement accuracy, flexible configuration and good stability
