Three different structural types model of grape rain shed are established based on PKPM-GSCAD software, and their
displacement and maximal stress are compared when wind speed is 20 meters per second. Simulation shows that the
wind load performance of model 2 is better than model 1. The horizontal displacement maximal value of model 2 is
1962mm when wind velocity is 20 meters per second. The model 3 is constructed by adding ventilation on model 2.
Take the model 3 as an example, and its wind field model is designed and simulated on the basis of CFD principle and
FLUENT 6.2 software.Simulation results show that model 3 grape rain shed has good wind load and ventilation
performance, so it has a good prospect in viticulture
