Snow project wind resistance test and simulation training system using wind tunnel

Abstract

The invention provides a snow project wind resistance test and simulation training system using a wind tunnel. The system comprises a wind tunnel, a force measuring balance, a camera monitoring device, an information real-time display device and a posture adjusting device. The force measuring balance is fixedly installed on a bottom plate of the wind tunnel, the posture adjusting device is fixedly installed on the force measuring balance and connected with a user, the camera shooting monitoring device is fixedly installed on the inner wall of the wind tunnel in a multi-position mode and carries out multi-angle real-time shooting on the user, and information pictures of the information real-time display device are 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, the force measuring balance measures wind resistance data borne by the user, and wind resistance, wind speed, monitoring picture data and action instruction information are integrated into the pictures of the information real-time display device. The system provided by the invention uses quantitative wind resistance to help coaches and users to carry out posture optimization and intensive training of key technical actions and assist technicians to carry out research and development of high-performance sports equipment.

Description

technical field [0001] The invention relates to the technical field of simulation training for snow sports, in particular to a wind resistance test and simulation training system for snow sports using a wind tunnel. Background technique [0002] During the sports of snow sports (such as alpine skiing, cross-country skiing, freestyle skiing, snowboarding, etc.), the wind resistance caused by the speed of movement is the largest resistance, which has a great impact on the competition performance. The size of the wind resistance is closely related to the user's exercise posture and exercise equipment. [0003] According to the principle of relative motion, the wind speed in the wind tunnel can be used to simulate the speed of snow sports. In this environment, it is convenient to carry out attitude wind resistance optimization, equipment wind resistance optimization and intensive training. [0004] The shortcoming of the wind resistance simulation method of the snow project in ...

AI Technical Summary

Problems solved by technology

[0005] 1. It is impossible to accurately measure the wind resistance experienced by snow sports athletes on the actual field, and the wind resistance can only be calculated in reverse based on an idealized model, so the error is relatively large;

[0006] 2. Under the existing technical conditions, it is impossible to optimize the posture of athletes' key technical movements through the quantitative data displayed in real time

[0007] 3. Under the existing technical conditions, the athlete's posture optimization mostly relies on experience, and the effect is not good;

[0008] 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
