Problems solved by technology

After the difficulty increases, there will be stricter standards for the height and weight of the athletes. Because the current FINA rules for determining the difficulty coefficient of the 10-meter platform diving do not set a body shape correction coefficient, the current evaluation method for the difficulty coefficient lacking in fairness

Embodiment

[0091] Let's take Guo Jingjing's height of 1.63m and weight of 48kg as an example, bring it into the above model, and find a new equation Among them, n is the number of tumbling cycles (half of the number of tumbling circles). The calculation results are shown in the table below. It is obvious that our results are quite different from the original difficulty coefficients in Table 1.

[0092] The reason for the difference is consistent with the above answer,

[0095] [Description of action codes] (1) The first digit indicates the frontal orientation of the athlete before take-off and the direction of somersault, 1, 3 means facing the pool, 2, 4 means facing away from the pool; 1, 2 means somersault outwards, 3, 4 means toss inwards. (2) The third digit indicates the number of tumbling circles, for example, 407, which means turning the back to the pool and tossing inward for 3 a...

Abstract

The invention discloses a diving platform diving evaluation method with the addition of athlete figure coefficients. According to the method, a diving athlete is simplified into a rigid body with rotary motions. The relation between the diving time of the athlete and the weight and height of the athlete is described by researching the relation between the motion time of the rigid body and the massand length of the rigid body. The method comprises the following specific implementation steps that 1, simplifying the diving actions of the athlete into five stages; 2, modeling the diving action completion time of the athlete based on the height and weight of the diving athlete; and 3, establishing a new difficulty coefficient evaluation system of the diving athlete based on the model obtainedin the step 2, and specifically establishing the new difficulty coefficient evaluation system of the diving athlete according to the mathematical model of the diving action completion time of the diving athlete and the height and weight of the athlete. According to the method, the athlete figure coefficient can be well obtained.

Description

technical field [0001] The present invention relates to the field of rigid body dynamics, specifically, it is a rotating rigid body motion that adds the body shape coefficient of divers into it, and provides a more fair evaluation method for platform diving Background technique [0002] The Chinese diving team started to lead the world in the 1990s. The Chinese diving team has achieved brilliant results that have attracted worldwide attention in many world competitions, and is also called the "dream team" by the Chinese. However, with the continuous improvement of the difficulty of movements in world diving and continuous innovation, the Chinese diving team has no obvious advantage in the difficulty of movements. Especially in the men's 10-meter platform event, from the 2004 Athens Olympics in Greece to the 2012 London Olympics, my country has never reached the highest podium in the men's 10-meter platform. Looking at today's diving powerhouses, all of them are constantly m...
