1. What is the structure of speed skating knife and shoes

One of the most important equipment of the skating project is the ice knife on the feet. The structure of the ice knife of different ice skating projects is also different. Speed skating knife shoes are ice -knife shoes worn on speed skating. There are two types of short track speed skating and avenue speed skating. TheyAlthough there is a large difference in appearance, its structure is basically the same, mainly consisting of the following parts:

1. Ice knife:Speed skating emphasizes the speed of gliding, so the ice knife is long, the blade is narrow and flat, and the ice knife of the speed skating knife shoes is only fixed with the ice shoes. This structure can extend the athlete's pedal distance and allow the athlete's ankle activity to increase the amplitude of the ankle joint activity.Large, Smooth exercise.

2, knife support:The knife holder of the speed skate shoes is fixed on the soles of the shoe by two points, which can move the position of the ice knife left and right. Generally, the short -sized skate -shoe ice knife has a higher knife.It will contact the ice surface; the avenue speed skating knife shoes are low.

3. Boots:The boots of speed skating knife shoes are generally made of carbon fiber and thermal shrinkable plastic shoe shells. While reducing the quality of ice shoes, the rigidity is improved, the leg load is reduced, the stability of the support is strengthened, and the stability of the support is enhanced.efficiency.

2. What is the principle of speed skating knife shoes

The structure of the speed skate shoes and the other two types of Ice knife shoes is different, but the basic principles are the same, mainly using ice knife to pedal ice, so as to slide on the ice. The specific principle is:

As we all know, people can walk on the ground because the soles and the ground have friction. The greater the friction, the more stable people can walk.And ice skating is just the opposite, the smaller friction can make the movement smoother.After putting on Ice knife shoes, there is a layer of water in the contact position of the ice knife and the ice surface. This layer of water plays a lubrication effect, so that people can slip on the ice surface. There are several different reasons for the cause of this layer of water:

1. The theory of stress fusion

The ice knife puts a lot of pressure on the ice, which will melt the ice surface and cause a thin water layer.When a person passing by, the pressure on the ice disappears, and the part of the water layer will re -condense into ice.

2. Surface melting theory

In recent years, the physics community has had a lot of doubts about this theory.If the role of stress melted the ice surface, it is obviously unrealistic that the athlete's weight can reach at least 175 kg to provide sufficient pressure, so the pressure effect is not the main reason for the melting of the ice surface.As a result, scientists also proposed the "surface melting theory", and its intention is that the surface of the ice always has a layer of water that will not melt; the higher the temperature, the thicker the water film, it is the lubrication effect of this layer of water.This is also a saying widely recognized in the physics community.

In general, the principle of Ice knife shoes is to lubricate the water film generated by the ice knife melting the ice surface, reducing the friction between the ice knife and the ice surface, so that people can glide on the ice surface.
