Abstract

The invention relates to a force characteristic calibration method for a water resistance tractor. A swimming traction device with a traction rope and a dynamometer is adopted. The method comprises steps: the traction end of the water resistance tractor is connected with the tail end of the traction rope of the swimming traction device; the swimming traction device draws the water resistance tractor to advance for a preset distance in the water according to a preset speed, the dynamometer of the swimming traction device measures the pulling force value borne by the traction rope, and the average pulling force value is calculated; whether to continue speed-pulling force calibration is judged, if yes, the measurement is continued, and if not, all acquired speed and average pulling force value data are used as acquired data; with a speed as a horizontal ordinate and a pulling force value as a longitudinal coordinate, the acquired data are adopted to make a curve graph; and the obtained curve graph is used as a force characteristic graph for the water resistance tractor. The method of the invention can calibrate the force characteristics of the water resistance tractor in a graphic curve mode, load quantization is achieved, and training use is facilitated.

Description

technical field [0001] The invention relates to a method for calibrating force characteristics of a resistance puller on water, and belongs to the technical field of calibrating training equipment in swimming water. Background technique [0002] As far as the inventor knows, swimming training for swimmers usually includes training on land and training in water, wherein loading training is usually applied to training on land, but rarely used in training in water. The reason is that in land training, the load loading of training equipment is quantifiable and adjustable, and the coaches can increase or decrease the load loading according to the actual training situation, so as to achieve the purpose of training and realize scientific training; however, At present, there is no training equipment specially designed for training in swimming water, and the load load can be quantified and adjusted, which makes it difficult to carry out scientific and effective load training during w...
