Device and method for measuring the rebound height of a sphere

Abstract

The invention provides a ball body bouncing height measuring device and a method of measuring ball body bouncing height with the device. The ball body bouncing height measuring device comprises a machine base, a bouncing floor, a release mechanism and a detection mechanism. The bottom of the machine base is provided with the bouncing floor. The upper portion of the machine base is provided with the release mechanism. The mid-bottom of the machine base is provided with the detection mechanism. The ball body bouncing height measuring device is simple and reasonable in structure, easy to produce, low in production cost, reliable in performance, high in automation degree, accurate in detection and wide in application range and occupies less space. The ball body bouncing height measuring method is simple in principle and is wide in application range and guarantees the accuracy of results; detection results are more approximate to actual bouncing height.

Description

technical field [0001] The invention belongs to the field of ball testing, in particular to a ball rebound height measuring device. The invention also relates to a method for measuring the rebound height of the sphere. Background technique [0002] A ball is a sporting item. The bounciness of the sphere directly affects the use effect of the sphere, which is very important. There are certain parameter requirements for the bounce height of various balls. In the prior art, the rebound performance of the ball is mostly tested by the touch of the inspector, which is prone to deviation. The results of this manual test vary from person to person, with low stability and repeatability, and too much subjectivity. And it is impossible to reach an agreed standard. In addition, the design of the current ball rebound height testing device is outdated, the accuracy of the test results is not enough, and the equipment is expensive. Therefore, it is an urgent need for ball product ente...

Problems solved by technology

[0003] At the same time, the current method of measuring the rebound height of the sphere also has many defects: (1) the sphere needs to be artificially raised to a certain height during the detection process, and the sphere needs to be controlled by manpower, which cannot eliminate the influence of human factors; (2) the data in the detection process The acquisition method generally adopts direct optical acquisition or acoustic acquisition scheme, which cannot eliminate the deviation caused by naked eye recognition or environmental noise, so that the accuracy of the result is insufficient; (3) the sphere falls by manual release, which cannot avoid the palm The interference of other factors such as the friction force of the sphere, and the influence of human factors cannot be eliminated
