Abstract

The invention discloses a novel micro-control static friction coefficient tester, belongs to the field of measuring instruments and aims to solve the problems that testing of static friction coefficient of sports facilities such as a side horse and a balance beam by manual push-pull methods in the prior art wastes time and effort and low in accuracy. When static friction coefficient of the balance beam is tested by the novel micro-control static friction coefficient tester, a testing block 23 is put on a balance beam 15. A testing mechanism finishes controlling of testing actions of the tester in a test controlling software interface. Specific actions for finishing one testing process include testing beginning, starting of a reciprocating driving servo motor, automatic displaying of curves of records, pulling force and time, calculating of the maximum static friction coefficient, stopping of the reciprocating driving servo motor, reverse starting and returning to a starting position of the reciprocating driving servo motor, and stopping of the reciprocating driving servo motor. After all testing processes are finished, data are automatically managed and calculated, and testing records are stored, printed and output. Testing accuracy and efficiency can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a novel micro-control static friction coefficient tester. Background technique [0002] In the prior art, the manual push-pull method is usually used to test the static ring friction coefficient of sports equipment such as pommel horses and balance beams. The test method is relatively primitive and backward. This method has a lot to do with the experience of the tester, and the accuracy of the recorded data is difficult. Guaranteed, during the push-pull test, it is difficult to grasp the direction of the force and the level of the test block. In addition, there are errors in the calculation, so the test results of the static friction coefficient of the equipment are quite different from the actual ones. Contents of the invention [0003] The purpose of the present invention is to provide a tester that can automatically test the static friction coefficient of sport...
