The computer simulation design technology plays a very important role in the construction of large venues, which can not only improve the quality of building construction but can provide information technology reference for the construction process. In the process of constructing sports venues, the lights of the stadium cann t produce vertiginous effect due to the need of indoor sports activities. By applying computer simulation technology, using catia software to build model for the venue and taking advantage of workbench software to make simulation for the light in the venue, this paper obtainhe light effect of the stadium under the function of three kinds of tubes and the tubes of different intensity. Thus, it providehe technical reference for the application of computer information technology to the construction of sports venues. Introduction Based on the combination of catia and workbench software, modeling and numerical simulation analysis are carried out on the venues. Numerical simulation is established by using catia and the data is analyzed by taking advantage of the workbench software. The specific process is as shown in Figure 1. Fig.1 Numerical simulation analysis for venue design As shown in Figure 1, the setting simulation of the venue is established by using catia and light simulation is done in workbench. By using oint control of catia and the workbench, this paper realizehe optimization design of building lighting and provideechnical reference for the construction process. Research on computer data correlation algorithm In the process of constructing stadium, the meaning of the computer simulation io provide technical support for the venues. Therefore, the simulation results must be dealt with technology and correlation algorithm ihe most commonly used treatment technology. Firstly, i showhe n results to be chosen and its number is i = 1,, n. expresses n indexes = 1,, n and mi meanhe th variable schemes of the i th scheme to be selected. Through transforming the property, this paper can obtain the best and worst values. In order to maximize the optimum value and minimize the worst value, the data iransformed as shown in formula (1).

2 Applied Mechanics and Materials Vols Cost target standardization formula max max min bi = ( m i ) /( m ) (2) Grey correlation coefficient calculation formula can be expressed as min min m0 + ρ max max m0 ξ ( k) = m0( k) i ( k) + ρ max max m0 (3) Among them, ρ [0,1] is distinguish coefficient. k showhe weighted coefficient. min min m0( t) expressehe minimum of two differential and max max m0 means s t the maximum of two differential. The calculation formula of gray weighted correlation degree is r i = n k = 1 w ξ ( k) (4) i r i showhe gray correlation degree of the i th simulation results plan on ideal simulation result plan. Figure 2 showhe correlation computation result which is obtained by calculation. From the Figure, it can be seen that this paper can not know the size of the correlation from the computer simulation results at all. And correlation coefficient distribution is more evenly distributed. After operation of computer correlation, there appears density distribution in the correlation, thus it verifies the effectiveness of the algorithm. The application and study of computer information technology in the construction of stadium Construction engineering of stadium is a very complicated process and needs constant test to achieve the optimization of design parameters. This article appliehe method of numerical simulation to optimizing the design of light glare scheme in the process of constructing stadium. At the same time, this paper takehe combined control method of catia and workbench software to make simulation for the effect of the lighting. Thus, the best solution of lighting layout is obtained. Firstly, the catia software is used to model the venues. The built model is shown in Figure 3. s t Fig.3 Venue construction catia model Fig. 2 Correlation operation result Figure 3 showhe catia model of venue construction. The whole venue is divided into different areas. This article selects one of the areao make design for lighting scheme and through the workbench catia can be imported. Fig. 4 Importing catia model

After importing the model, grid can be divided and the physical condition can be set up. This paper takehe way of coupling calculation to directly make parameter coupling between the model and environment, as shown in Figure 5. Fig. 5 Coupling analysis of stadium building environment Figure 5 expressehe process of setting up building venues environment coupling, in which the position of the tube is arranged as shown in Figure 6 for simulation. Fig.6 Simulation of stadium lighting layout Figure 6 showhe location of the stadium lights simulation. In order to achieve the best glare effect, this paper acquirehe minimum shading angle of lamp shown in table 1 through the computer correlation analysis. Tab. 1 Design for the minimum shielding light angle of venues Level of anti-dazzle light in venues Straight torch brightness Fluorescent lamp brightness Incandescent lamp brightness Table 1 expressehe design angle of minimum shielding light angle in the venues. After setting the position and tube angle,the numerical simulation can be carried out, through which, the convergence curve is obtained as shown in Figure 7. Fig.7 Calculation convergence graph of workbench Figure 7 showhe convergence effect of applying relevance law and not applying it. From the Figure, it can be seen that the calculated convergence effect without using the correlation rule is not good and there exists bigger error. However, by using the correlation algorithms rule, the calculation convergence is better and the error is smaller. Figure 8 expressehe computer simulation rendering of a room in the stadium venue. From the Figure, it can be obtained that the lighting effects of different positions are different. The overall lighting is soft and will not produce strong glare or dazzling effect. Thus, it is suitable to be used as sports venues and also verifiehe accuracy of the simulation design in this paper.
