Abstract

The invention relates to a table tennis and table tennis table surface elasticity measurement device and method. The measurement device comprises a housing, a base, a release device, a sound-sensitivesensor, a microcomputer and an acousto-optic display device. The housing is a hollow cavity. The base is arranged under the housing. The top portion of the housing is provided with a circular hole. The release device is arranged under the circular hole. The housing is provided with a wind release hole, which can eliminate wind resistance caused by the sealed cavity in the ball falling process toensure test accuracy. The housing is internally provided with the sound-sensitive sensor, the microcomputer and the acousto-optic display device. The microcomputer is connected with the sound-sensitive sensor and the acousto-optic display device. A battery provides power for all electric devices. The measurement device and method can realize scientific and quantitative test of the elasticity of atable tennis table and a table tennis to enable the table tennis equipment to fully comply with international standards; and besides, the measurement device is small in size and convenient to carry and use.

Description

technical field [0001] The invention relates to a measuring device, in particular to an elastic measuring device and a measuring method for a table tennis ball and a table tennis table top. Background technique [0002] At present, the International Table Tennis Federation (ITTF) has unified technical standards and corresponding technical requirements for all the main equipment participating in table tennis competitions, that is, table tennis balls and table tennis tables, especially the elastic requirements for table tennis balls and table tennis tables. It has clear technical parameter indicators. For example: test requirements: release the table tennis ball from a place 300mm away from the table tennis table, and the rebound height must be within 230-260mm to be qualified; table tennis balls or table tennis tables higher or lower than this standard should be unqualified. At present, the tests of the above-mentioned international standards at home and abroad all use subje...
