Abstract

The invention provides a steel frame snowmobile wind resistance testing and simulation training system using a wind tunnel. The system comprises a wind tunnel, a force measuring balance, a camera monitoring device, a real-time information 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 a user leans on the steel frame snowmobile through the posture adjusting device. Wind generated by the wind tunnel blows to the user, the posture adjusting device assists in adjusting the posture of the user, 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 an information picture of the real-time information display device displays the wind speed of the wind tunnel, the wind resistance data, a motion posture control command to the user and the like in real time. According to the device, quantified wind resistance is used for helping a coach and the user to carry out posture optimization and intensive training of key technical actions, and helping technicians to carry out 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 particular to a steel frame snowmobile wind resistance test and simulation training system using a wind tunnel. Background technique [0002] During the movement of sled events (such as steel frame snowmobile, luge, snowmobile, 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. 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] According to the principle of relative motion, the speed of the steel frame snowmobile can be simulated by using the wind speed in the wind tunnel. In this environment, it is c...
