The design structure of the large diameter square cone shaped air duct was improved,it is proposed that the design of the guide plate and the external reinforcement rib should be considered comprehensively for the air duct with a large proportion of length to width,with the help of the guide plate,the single air duct was separated into multiple cavities,so that the guide plate could bear the dual functions of the diversion and tensile load,in this way,the specification of the external reinforcement rib and the air duct wall plate could be greatly reduced.Use Solidworks software to establish the structure model before and after optimization,conduct finite element analysis,and compare the analysis results under design pressure.The conclusion is that the stress value of the optimized structure is low and the deformation is very small,which can save more than 50%of the materials.
