Analysis and Research on Defrosting Ventilation Pipe Deformation of Automobile

Abstract

: According to the market feedback, automobile defrosting ventilation pipe does not fit in the top 10 of xiangtan geely automobile market quality problems. According to the detection of vehicles in this condition, the reason for the deformation of automobile defrosting ventilation pipe position is that the gap between instrument cover and ventilation pipe is less than 4mm. Ventilation tube ends around not level off, the present state of collapse, and the intensity of this state collapse is due to the lack of overall deformation, for deformation reasons of automobile ventilation pipe outlet increase 11 on the back of the improved design scheme of reinforcement, using the method of three-dimensional modeling, design parameters, according to auto defrost ventilation tube through the Pro/E 3 d software to complete the ventilation pipe before and after the improvement model, using ANSYS Workbench software of finite element analysis was carried out on the ventilation pipe before and after improvement, the maximum deformation analysis ventilation pipe outlet, After the improvement, the deformation amount decreased from 10.643mm to 10.283mm, and the maximum stress value of the ventilation pipe decreased from 85.783MPa to 55.781MPa, less than the ultimate strength of 70MPa, verifying the rationality of the improved design, Solve the quality problem for the enterprise, have very good reference value.
