双优化POD法在复杂屋盖风压场模拟中的应用
Application of the Double Optimized Orthogonal Decomposition Technique in the Simulation of Wind Pressure on the Complex Roof
摘要
Abstract
In complex roof structures,the measuring point area and wind pressure of double root variance optimization can be input to carry out using the double optimized orthogonal decomposition technique.Taking the intrinsic load mode in the double optimization as the object,two kinds of interpolation methods were employed to simulation the wind load.At the same time,the average,root variance and wind pressure duration were compared with the simulated wind pressures using the two interpolation methods on.The results show that the interpolated wind load based on the double optimized orthogonal decomposition technique can achieve an ideal prediction effect.However,there are differences in the simulation results and the node position between the two interpolation methods.On the whole,the simulation effect at the zone with less turbulence is better than the turbulent zone node for the node position for both the interpolation method 1 and method 2;If the interpolation method is concerned,the interpolation method 2 is better than the method 1 in the turbulent zone nodes.At the same time,the interpolation method 1 is better than the 2 in the zone with a small wind load distribution gradient,but at the node,when the wind load distribution gradient is large,the interpolation method 2 is better than the method 1.关键词
