Folding reticulated shell structure shape optimization based on wind pressure distribution characteristics
摘要
Abstract
As a kind of wind‐sensitive structure ,the folding reticulated shell has mechanical behaviors of weak area to wind‐resistance and large wind pressure gradient .To optimize the superficial wind pressure distribution and reduce the wind‐induced responses for folding reticulated shell ,a fundamental study was conducted by using the software FLUENT ,which was based on the fluid dynamic theory and the atmospheric boundary layer theory .According to the wind tunnel test results ,some key parameters were discussed including the computational domain size ,the computational domain discrete and the turbulence model .On this basis ,8 shape optimization schemes of folding reticulated shell were analyzed and the partition shape coefficients and their standard deviation were obtained accordingly .Through comparing with the initial surface wind pressure of the structure ,an optimal scheme was gotten finally ,which has good performance of wind‐resistance and can relieve the adverse distribution of wind pressure effectively . T he results indicate that the CFD numerical analysis method is applicable in the shape optimization of wind‐sensitive structure ,and it provides an effective method for the design of new camping houses .关键词
