Semi-closed Tennis Court Optimization Design Based On Wind Environment And Structure Simulation

With the implementation of healthy China strategy,the traditional concept of health has been constantly updated,and the relationship between national health and sports has been redefined.With the rapid development of traditional sports industry,the construction of stadiums is also in full swing.The construction of tennis venues in China started late,the number is insufficient and the construction level is backward.This background restricts the development of tennis.The wind environment of semi closed professional tennis court for the fairness of the game and the comfort of spectators are also gradually paid attention to.The development of tennis is in a rising period.Natural conditions are an important obstacle to its professionalism.The poor environmental quality of semi closed tennis courts has certain "harm" to both players and spectators.In the process of tennis competition,due to the influence of wind,the direction and speed of the ball will change,which will affect the control degree of the ball and the fairness of the game,and the comfort of the players and the audience will also be reduced.Most of the existing professional tennis courts are outdoor,which is greatly affected by the wind environment and can not meet the needs of the game.Therefore,it is urgent to study the internal wind environment of semi closed tennis courts.Tennis court is smaller in size and less constrained by structure than large stadium or football field.The most important part of the structural diversity of tennis court is the diversity of its canopy structure.Different canopy structures bring different design effects,which makes architects tend to be sensitive and rational in the selection of canopy structure.Therefore,how to design a semi closed tennis court,not only to meet the needs of the audience and athletes for the wind environment,but also to make the tennis court canopy structure more reasonable and efficient,is an urgent problem to be solved.According to the double rationality of wind environment and structure of semi closed tennis court,this paper discusses its optimal design form.Based on the field measurement and questionnaire survey of wind environment in representative cities in cold regions,the wind speed range of outdoor related activities is defined,and the wind speed reference standard under the temperature condition of tennis match in China is obtained.The semi-final field of Tianjin tuanbo International Tennis Center was selected as the test site,and the simulation results were compared with the measured wind speed to verify the reliability of CFD experimental platform.Based on the data of 130 professional tennis courts at home and abroad,the capacity of the tennis courts simulated in this paper is 6000.In the simulation of wind environment performance,the plane shape of tennis court is square and round,the profile of canopy is inclined upward,straight and downward,and the permeability of top interface is 25%,50% and 75%.On the basis of the ideal model of wind environment simulation,the paper refines the model of semi closed tennis court canopy structure,selects two structural forms of grid and truss as the research object,and discusses the rationality of the canopy structure.Through the multi-objective optimization research on wind environment performance and structural performance,this paper provides a rational design strategy for the shape optimization of semi closed tennis courts in China.
