Wind resistance test and simulation training system for steel frame snowmobile under track environment using wind tunnel

Abstract

The invention provides a wind resistance test and simulation training system for a steel frame snowmobile in a track environment using a wind tunnel. Including: wind tunnel, force balance, camera monitoring device, real-time information display device, track and attitude adjustment device; the force balance is fixedly installed on the bottom plate of the wind tunnel, and the attitude adjustment device is fixed on the force balance and embedded in the On the bottom plate of the track, the user uses the posture adjustment device to lie on the steel frame snowmobile; the wind generated by the wind tunnel blows towards the user, and the posture adjustment device assists in adjusting the user's posture. The camera monitoring device records the user's real-time motion video and measures the force. The balance measures the wind resistance data received by the user, and the information screen of the real-time information display device displays the wind speed of the wind tunnel, the wind resistance data and the user's motion posture control commands in real time. The device of the present invention uses quantified wind resistance to help coaches and users perform posture optimization and intensified training of key technical movements, and assist technicians in research and development of high-performance sports equipment.

Description

technical field [0001] The invention relates to the technical field of steel frame snowmobile simulation training in the track environment, in particular to a steel frame snowmobile wind resistance test and simulation training system in the track environment using a wind tunnel. Background technique [0002] Skeleton is an official event of the Winter Olympics, and the difference in competition results is often a few hundredths of a second. In order to improve performance, it is necessary to optimize the wind resistance performance of key technical movements and equipment, and carry out intensive simulation training for key technical movements. [0003] During the movement of sled events (such as steel frame snowmobile, sled, snowmobile, etc.), the wind resistance caused by the speed of movement is the largest resistance, which has a great impact on the competition results. The size of the wind resistance is closely related to the user's exercise posture and exercise equipm...

AI Technical Summary

Problems solved by technology

[0006] 1. It is impossible to accurately measure the wind resistance on the user and sports equipment in the actual site, and the wind resistance can only be reversed through an idealized calculation model, with large errors

[0007] 2. Under the existing technical conditions, quantitative data cannot be used to optimize the posture of the user's key technical actions;

[0008] 3. Under the existing technical conditions, the user's posture optimization is mostly based on experience, and the effect is not good

[0009] 4. Most of the research and development of sports equipment is based on mannequin model tests, which cannot quickly and accurately evaluate the wind resistance performance of sports equipment
