Abstract

The invention relates to the field of material preparation and device application and particularly relates to an intelligent table tennis bat based on an electrorheological elastomer and a preparation method of the intelligent table tennis bat. The intelligent table tennis bat comprises a voltage supply module, a wooden bat and composite rubber sheet, wherein the composite rubber sheet is composed of an electrode plate I, an electrorheological elastomer, an electrode plate II and a rubber sheet; the electrode plate I is fixedly connected with a front surface of the wooden bat; the electrorheological elastomer is connected with the voltage supply module through the electrode plate I and the electrode plate II; the voltage supply module provides an adjustable voltage for the electrorheological elastomer so as to change the energy storage modulus and hardness. The intelligent table tennis bat is advantaged in that by adding the anisotropic electrorheological elastomer, surface hardness of the racket is adjusted, and the compression modulus parallel to the direction of an electric field and the shear modulus perpendicular to the direction of the electric field are improved; when an external electric field is applied, lower energy loss is achieved, and more initial kinetic energy is converted into kinetic energy for ball discharging, so the ball discharging speed of the racket is increased, meanwhile, an emitting angle of ball hitting is effectively adjusted and controlled, and training of unconventional techniques is achieved to adapt to ball playing styles of different athletes.

Description

technical field [0001] The invention relates to the technical field of material preparation and device application, in particular to an intelligent table tennis racket based on an electrorheological elastomer and a preparation method thereof. Background technique [0002] There are unconventional technical trainings in table tennis and other ball games, such as receiving rare, sudden balls that are difficult to deal with with conventional techniques, such as edge kicks, tennis balls or fake moves, etc. .
