Embodiment 1

[0065] A static calibration method for a three-dimensional force-measuring platform of the present invention. Firstly, the three-dimensional force-measuring platform static calibration device is used to calibrate the three-dimensional force-measuring platform on-site, and then various parameters after calibration are input into the calibration algorithm formula to obtain the calibration coefficient. C , and finally verify the calibration results; specifically, the following steps are included:

[0066] Step 1: Place the three-dimensional force measuring platform (16) in a preset pit, and use a static calibration device for the three-dimensional force measuring platform to calibrate the three-dimensional force measuring platform (16) on site.

[0067] refer to Figure 5 , this time, the DYT6040-1 piezoelectric three-dimensional force measuring platform (specification length: 60cm, width: 40cm, height: 10cm) produced by Dalian University of Technology is used as the calibration ...

Abstract

The invention relates to the field of physical exercise analysis, human body gait research, orthopedic rehabilitation walking function evaluation and the like, and discloses a device and method for onsite static calibration of a three-dimensional force platform. The method comprises the steps of firstly carrying out onsite calibration on the three-dimensional force platform by using the device for the onsite static calibration of the three-dimensional force platform, then inputting various parameters after the calibration into a formula of a calibration algorithm to obtain a calibration coefficient C, and finally carrying out verification on a calibration result. The device and method for the onsite static calibration of the three-dimensional force platform can calculate the calibration coefficient on site through the formula, enables factory returning for recalibration to be needless, solve the problem of inaccurate calibration coefficients caused by the using period of equipment, improper mounting or collision, and have certain market prospects and application value.

Description

technical field [0001] The invention relates to the fields of sports analysis, human body gait research, orthopedic rehabilitation walking function evaluation, and in particular to an on-site static calibration device and method for a three-dimensional force measuring platform. Background technique [0002] Since the first use of a three-dimensional force measuring platform in the gait research project of the University of California in 1952, the force measuring platform has become the standard dynamic force for measuring ground reaction force in the fields of sports research, human gait research, and orthopedic rehabilitation walking function evaluation. learning testing tools. The force plate can provide indicators such as force, torque, torque, force angle, impulse and pressure center position, and analyze the characteristics of force changes during human movement very intuitively. The force and moment are the original output data, and other indicators are calculation in...
