Abstract


Membrane structure as in recent years, a wide range of new large- span space structure of one of its significant characteristics of structure , light weight, flexible large damping belongs wind sensitivity structure . Complex due to the body shape of the membrane structure , at home and abroad through the wind tunnel test method to determine the wind pressure coefficient , membrane structures of the various forms of wind tunnel tests carried out but also extremely limited enough regularity . Relying the ANSYS-CFX13.0 software platform , this research work around the mean wind field numerical simulation based on the membrane structure of the Reynolds averaged simulation (RANS) method , mean wind field effect of this type of structure to expand the system in-depth study has important theoretical significance and practical value . This article first to select CAARC standard high-level architectural model for the object as a reference , Tongji University TJ-2 wind tunnel tests to establish the site measured wind field data as the real flow boundary conditions mesoscale numerical model , using ANSYS-CFX 13.0 platform commonly based on the Reynolds-averaged (RANS) turbulence model to examine the computing domain , meshing , boundary conditions , turbulence model and calculation parameters determine the method of numerical wind tunnel . By calculating the comparison of the results with the measured data and the results of wind tunnel tests verify the feasibility and correctness of the numerical wind tunnel simulation conditions , and to explore the applicability of two turbulence model for numerical simulation analysis . In this paper, the finite element calculation software ANSYS 13.0 saddle membrane structure and hexagonal umbrella film structure form-finding analysis and extract the geometric model of the membrane structure , import the fluid domain , and then divided the flow around a grid to establish the film structure computational fluid dynamics model , thus achieving the numerical simulation of the flow around a mean wind field on the membrane structure . Membrane structure for the two basic body type - saddle , umbrella , analysis of different wind direction , the different span ratio and high cross- ratio and other factors on the surface of the membrane structure wind pressure coefficient distribution law , and gives the corresponding membrane surface wind pressure coefficient distribution for engineering design .
