Abstract

The invention provides a wind tunnel test short-track speed skating mannequin which comprises a mannequin body, a simulated human body liquid silica gel layer and simulated human body liquid silica gel layer. The dynamic posture of the mannequin body is consistent with that of short-track speed skating, the mannequin body is composed of a right leg part, a left leg part, a hip part, a left arm, a right arm, an upper body and a head part, and all the parts are connected and fixed through magnetic disk buckles and screws; the simulated human body liquid silica gel layer covers the outer surface of the mannequin body; and the simulated human body liquid silica gel layer are embedded into the simulated human body liquid silica gel layer, and the surfaces of the twenty flexible force sensors are fixed by using simulated skin adhesive tapes. The invention also provides a method for determining the position of the short-track speed skating mannequin pressure test point in the wind tunnel test, and the position is determined through calculation of a Reynolds number formula. The device can realize simultaneous measurement of multi-point pressure, and can be conveniently and effectively used for wind tunnel air resistance testing.

Description

technical field [0001] The invention belongs to the technical field of wind tunnel testing, in particular to a short-track speed skating mannequin for wind tunnel testing and a method for determining a testing position thereof. Background technique [0002] In competitive sports, athletes need to constantly overcome various resistances, such as wind resistance, water resistance, etc., to complete the competition at a faster speed and achieve good results. The so-called wind resistance, that is, air resistance, the main factors that determine the air resistance during the athlete's exercise are the athlete's posture, equipment, accessories and competition clothes in the game. Among them, the air resistance is basically determined by the athlete's posture. After optimizing the posture, designing a scientific speed skating suit is one of the effective ways to reduce air resistance. [0003] The air resistance suffered by athletes mainly comes from pressure differential resista...
