Design And Evaluation Of Physical Model In Short Track Speed Skating Technical And Tactical Simulation System

Physical plays an extremely important role in short track speed skatingmovement. So it’s very necessary to design a scientific and reasonable physicalmodel, which will make the short track speed skating technical and tacticalsimulation system simulate virtual athletes’ state of motion during the race real andimprove the practicality of the simulation system.This paper designs and achieves a physical model based on real human energysupply system with the method of system modeling, according to the bionics. Thephysical model calculates and denotes the real-time physical state of short trackspeed skating athletes during the race through simulate the rule of human body’senergy generating and consuming in the course of campaign. In the same time, themodel shows effect on athletes’ state of motion such as velocity, acceleration, andso on. It accomplishes the simulation of human body’s energy system and thefeedback on athletes’ athletic ability. This paper makes some research on theprinciple of human’s real energy system and gets a biological prototype with theuseful information screening out from the principle purposefully. Next, it abstracts amathematical model, using the methods of mathematics such as deductive, inductive,assumptions validation, and so on, based on the biological prototype. Lastly, itdevelops a physical computing module of the short track speed skating technicaland tactical simulation system with software engineering technology.This paper also designs a series of performance and reliability evaluationmethods for the physical model recur to common evaluation methods and thespecific characteristics of physical and short track speed skating sports. With thehelp of experiments and knowledge of related areas, it makes scientific, rational,objective evaluation quantitatively and qualitatively for physical model from manyaspects. As a result, it verifies the credibility and availability of the physical model.During the creation and evaluation of physical model, this paper has studiedand described the system modeling and evaluation methods.
