Physical training test wind tunnel system and airflow forming and control method thereof

Abstract

The invention relates to a physical training test wind tunnel system and an airflow forming and control method thereof, and belongs to the technical field of physical engineering. The physical training test wind tunnel system provided by the present invention comprises a tunnel body, and a multi-degree-of-freedom motion simulation platform, an outdoor environment simulation unit, a data real-time monitoring unit, an airflow forming unit and an action posture capturing unit which are arranged in the tunnel body. The tunnel body is a closed backflow type tunnel body structure, and comprises a tunnel body training test section and rest sections of the tunnel body, and the rest sections of the tunnel body comprise a stable contraction section and a fan power section. The physical training test wind tunnel system provided by the invention can adjust various parameters of a sports environment in the wind tunnel system according to requirements, simulate an aerodynamic environment of a training test object in a competition site, and is used for evaluating a training state or a use state of a to-be-tested athlete or sports equipment in a specific sports environment; and technical support is provided for improving technical actions and optimizing and improving the performance of sports equipment.

Description

technical field [0001] The invention belongs to the technical field of sports engineering, and in particular relates to a sports training and testing wind tunnel system and a method for forming and controlling airflow therein. Background technique [0002] In many sports competitions, such as ball games, throwing, swimming, skiing, racing, etc., the improvement of sports performance and the improvement of sports equipment performance are closely related to aerodynamics. For example, American alpine downhill athlete Steve Naiman and Winter Olympic freestyle skiing champion Eric Gay have used wind tunnel drag reduction tests and training to continuously achieve good results, and it has become a model to improve performance through wind tunnel drag reduction tests and training. classic case. [0003] In order to further play the role of wind tunnels in promoting the development of sports and related equipment, European and American countries have established sports wind tunnel...

Problems solved by technology

[0003] In order to further play the role of wind tunnels in promoting the development of sports and related equipment, European and American countries have established sports wind tunnels, such as the Boardman wind tunnel just established in the UK in 2018, the Specialized wind tunnel in the United States, the Flanders BikeValley wind tunnel in Belgium, and the Swedish Sports Technology Research Center However, except for the wind tunnel of the Swedish Sports Science and Technology Research Center, which can change the temperature and humidity of the environment, none of these wind tunnels has a temperature and humidity control system for athlete testing and training. , attitude detection and multi-degree-of-freedom sports training platforms, and the wind tunnel of the Swedish Sports Technology Research Center is only applied in several snow-related sports and cycling events, and the application efficiency in the sports field is not high

As early as 2007, the Chinese utility model patent CN201175557Y "Aerodynamic training hall for sports training based on the wind tunnel principle" (the utility model patent has expired) proposed a training pipeline with a built-in wind drive device, although the device can Do some sports training, but basically can't get sports data
