Ice skate blade three-dimensional rigid bridge force measuring table and system

Abstract

The invention provides an ice skate blade three-dimensional rigid bridge force measuring table. The three-dimensional rigid bridge force measuring table comprises an upper rigid bridge, a lower rigid bridge, two three-dimensional force sensors and a motion measuring unit. The rigid bridge force measuring table is fixedly connected to the ice skate blade through the upper rigid bridge and the lower rigid bridge, and a front three-dimensional force sensor and a rear three-dimensional force sensor are fixedly installed between the upper rigid bridge and the lower rigid bridge and used for detecting the stress of the ice skate blade; and the motion measurement unit is used for detecting the spatial position of the rigid bridge force measuring table and is fixedly arranged at the rear part of the upper rigid bridge. The force measuring table can monitor the size and direction of three-dimensional ice pedaling force of an athlete, the position of a counter-acting force acting point and the opening and closing state of an ice skate blade in real time, and fills the blank of three-dimensional force measurement of speed skating sports in China.

Description

technical field [0001] The invention relates to sports equipment, in particular to an equipment capable of detecting the magnitude and direction of the force exerted on the ice blade, the opening and closing state of the ice blade, and the like when an athlete is skating. Background technique [0002] When a person walks or runs, a force is exerted on the ground through the foot, and at the same time, the ground gives the foot a reaction force. These vector forces are three-dimensional, and usually consist of a vertical force and two vertical components along the horizontal plane. composition. In speed skating, the human body exerts a force on the rigid body of the ice blade, pushes the ice sideways and backwards, forms a sideways and forward reaction force as a propulsion force, and then slides forward on the ice. [0003] In the field of sports, the feasibility and accuracy of three-dimensional force measurement in various sports are very important for scientific training...
