However, the high friction coefficient also causes some problems, such as the athlete can not experience the smooth feeling of sliding on the real ice when moving on the simulated ice field plate. Athletes, especially those who just start to practice, are very likely to have the phenomenon of sideslip due to the fact that the ice skate is embedded into the polymer ice field plate to a small depth when using a large side pedaling force. The occurrence of sideslip slightly increases the physical consumption of athletes, increases the psychological burden of beginners on the ice sports of the ice-imitating field, and seriously causes the unbalance of human bodies and the falling injury.

The invention can slow down the loss of the surface material with low friction coefficient, increase the pedaling force, improve the conversion efficiency from bioenergy to kinetic energy and prevent side falling; when the ice skate passes through the side-cut prevention material bundle, the lubricating liquid fully enters the blade passing through the fiber bundle, dry friction between the ice skate and the ice rink is changed into lubricating friction, the dynamic friction coefficient is reduced, the sliding resistance is reduced, and the sliding smoothness is improved.
A liquid lubricant is stored between the holes of the low-friction-coefficient thermoplastic plastic and the high-strength cutting-resistant untwisted fiber bundles; the liquid lubricant reduces the friction coefficient between the ice skate blade and the friction material, is beneficial to improving the acceleration during acceleration, reduces the friction resistance when a human body freely slides by inertia, prolongs the free sliding time and distance and improves the sliding smooth feeling experience.
The low-friction-coefficient thermoplastic plastic and the high-strength cutting-resistant untwisted fiber bundles are bonded or thermally welded into a whole through the thermoplastic adhesive, so that the installation stability of the low-friction-coefficient material is improved.
The high-strength cutting-resistant untwisted fiber bundles are uniformly distributed on the surface of the low-friction coefficient thermoplastic plastic in a clustered manner, so that the uniform performance of the anti-sideslip liquid lubricating functional layer is ensured.
The invention has the characteristics of simple structure, easy processing, easy maintenance and integral recovery, effectively reduces the sliding friction coefficient of the simulated ice board, reduces the possibility of sideslip in the process of pedaling the ground, improves the smoothness of the movement of athletes on the simulated ice board, and has important significance for popularizing the simulated ice board, expanding the laying area of the simulated ice board, driving more people to participate in winter movement projects such as the movement on the ice and the like.

The plate body is formed by sequentially compounding an anti-sideslip liquid lubricating function layer 2, a cementing layer 3 and a high-rigidity substrate material layer 1 from top to bottom; the anti-sideslip liquid lubricating functional layer 2 comprises low-friction coefficient thermoplastic plastics 4, holes of clusters are uniformly distributed in the low-friction coefficient thermoplastic plastics 4, and high-strength cutting-resistant untwisted fiber bundles 5 penetrate through the holes; a liquid lubricant is stored between the holes of the low-friction-coefficient thermoplastic plastic 4 and the high-strength cutting-resistant untwisted fiber bundles 5; the low-friction-coefficient thermoplastic 4 and the high-strength cutting-resistant untwisted fiber bundle 5 are bonded or thermally welded into a whole through a thermoplastic adhesive; the high-strength cutting-resistant untwisted fiber bundles 5 are uniformly distributed on the surface of the low-friction-coefficient thermoplastic plastic 4 in clusters.
The direction (downward) indicated by the arrow in fig. 2 is taken as the research direction, and the analysis sketch of the stress of a person on the simulated ice is shown in fig. 3 and fig. 4.
In the attached figure 3, the simplified human body is a particle, when the human body stands on an ice field, under the action of self gravity and pedaling the ground, the ice skate can easily penetrate through the high-strength cutting-resistant untwisted fiber bundle 5 soaked with lubricating liquid from the top and is pressed into the low-friction-coefficient thermoplastic plastic 4, when the lower limb pedals the knife, the blade meets the cutting-resistant material layer after cutting the low-friction-coefficient thermoplastic plastic 4 in the lateral direction, and the blade is prevented from continuously cutting the low-friction-coefficient thermoplastic plastic 4 deeply, so that the loss of the low-friction-coefficient thermoplastic plastic 4 is reduced, and the pedaling force is improved.
In the attached figures 3 and 4, V is the instantaneous motion direction of the human body, the included angle of the ice skates on the left foot and the right foot is theta, m is the mass of the human body, and F0The force of the lower limbs kicking the ground by the ice skate blade, a is the acceleration, the subscript v is the motion direction, the subscript n is the direction perpendicular to the motion direction, and f is the resultant force of the motion resistance force and the resistance force applied to the cut friction material layer.

F1The decomposition is carried out along the v and n directions to Fv and Fn;
the resultant force of the human body along the motion direction is F1COS theta-fv shows that the larger the human body kicking force is, the larger the included angle between the force application ice skate angle and the motion direction is, the larger the resultant force is, namely, the larger the acceleration is. The sideslip can reduce the pedaling force of a human body to be unfavorable for accelerating sliding, the smaller the resistance fv is, the larger the acceleration is, the lower the fv is to reduce the cutting resistance (related to the cutting thickness, the type of the cutting material and the structure of the ice skate) between the ice skate and an ice board material, details are not described here, and the other is to reduce the sliding friction force, so that the liquid lubrication reduces the friction coefficient between the ice skate and the friction material to be favorable for improving the acceleration during acceleration, reduces the friction resistance when the human body freely slides by inertia, prolongs the free sliding time and distance, and improves the sliding smooth feeling experience.
