On-ice project wind resistance test, simulating and training system using wind tunnel

Abstract

The invention provides an on-ice project wind resistance test, simulating and training system using a wind tunnel. The system comprises the wind tunnel, a force measuring balance, a camera monitoring device, an information real-time display device and an auxiliary supporting device. The force measuring balance is fixedly mounted on a bottom plate of the wind tunnel, the auxiliary supporting device is fixedly mounted on the force measuring balance and is connected with a user, and the camera monitoring device is fixedly mounted on the inner wall of the wind tunnel in a multi-position manner and shoots the user at multiple angles real-timely; the information picture of the information real-time display device is located on the bottom face, right in front of the user, of the wind tunnel, the camera monitoring device records a real-time motion video of the user, and the force measuring balance measures the wind resistance data, wind speed data, monitoring picture data and action instruction information borne by the user and integrates the data and the information into the picture of the information real-time display device. The system provided by the invention uses the quantitative wind resistance to help coaches and athletes to carry out posture optimization and intensive training of key skill actions and assist the technicians in research and development of high-performance sports devices.

Description

technical field [0001] The invention relates to the technical field of simulation training for ice sports, in particular to a wind resistance test and simulation training system for ice sports using a wind tunnel. Background technique [0002] During the sports on ice (speed skating, short track speed skating), the wind resistance caused by the speed of movement is the largest resistance, which has a great impact on the performance of the competition. The size of the wind resistance is closely related to the athlete's movement posture and sports equipment. [0003] According to the principle of relative motion, the speed of sports on ice can be simulated by using the wind speed in the wind tunnel. In this environment, it is convenient to carry out attitude wind resistance optimization, equipment wind resistance optimization and intensive training. [0004] The disadvantage of the wind resistance simulation method for ice events in the prior art is that the actual field cann...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the wind resistance simulation method for ice events in the prior art is that the actual field cannot accurately measure the wind resistance suffered by the ice event athletes, and the wind resistance can only be reversed based on an idealized model, so the error is relatively large;

[0005] Quantitative data displayed in real time cannot be used to optimize the posture of athletes’ key technical movements. The adjustment of athletes’ posture is mostly based on experience, and the effect is not good. It is impossible to quickly and accurately evaluate the wind resistance performance of sports equipment

[0006] Most of the research and development of sports equipment is based on mannequin model tests, which cannot evaluate the real wind resistance performance of athletes during exercise
