Abstract

The invention discloses a device and method for measuring the static rigidity of a tennis racket string. The device comprises a stepping motor, a lifter, a coupler, a pressure sensor, a cross-shaped fastener, a tennis racket clamping device, a laser displacement sensor, a pressing rod and X-Y linear guide rails. The stepping motor and the lifter are connected through the coupler, the lifter is installed at the bottom of a frame through a lifter installation plate, the top of a screw rod of the lifter is connected with the pressure sensor, the pressure senor is located below the cross-shaped fastener, the cross-shaped fastener is clamped to the string vertically, the aluminum profile pressing rod presses the tennis racket clamping device to the top of the aluminum profile frame, the linear guide rails in the X-axis direction are fixed to the aluminum profile pressing rod, the linear guide rail in the Y-axis direction is connected to sliding blocks of the linear guide rails in the X-axis direction through a guide rail connecting plate, the laser displacement sensor is connected with a sliding block of the linear guide rail in the Y-axis direction, and thus the laser displacement sensor can freely move along the plane. The device and method for measuring the static rigidity of the tennis racket string have the advantages that control is simple and reliable, and cost is low.

Description

technical field [0001] The invention relates to a measuring device, in particular to a device and method for measuring the static stiffness of tennis racket strings. Background technique [0002] Tennis is a beautiful and intense sport, highly competitive and entertaining, deeply loved by the masses, and is one of the most popular sports in the world today, known as the second largest ball game in the world. [0003] In China, tennis has become popular and has become a sport of the whole society. It has begun to attract more people's attention.
