A Novel Force Sensor Based Multi-Function Take-Off Board

Abstract:

In order to detect the take-off forces of athletes in long jump, a novel force sensor based take-off board is designed. The take-off board consists of a standard take-off board, two novel force sensors, two support plates and a base. The working mechanism of the strain beam in the force sensor is analyzed and the finite element method(FEM) is used to investigate the structural deformation and stress distribution. Then the sensor is tested. The calibration experimental results demonstrate that the sensor has an excellent measurement linearity (0.6%) and can meet the requirements of practical applications. Then the multi-function take-off board based on the force sensors is designed and manufactured which can make the daily long jump training more scientific.
