Abstract

The invention discloses a coating spray booth airflow velocity and pressure simulation method, which is operated based on SCDM, ICEM and Fluent software, and comprises the following steps: carrying out 3D modeling based on the SCDM; performing structure and mesh division on the 3D model generated through SCDM based on ICEM; carrying out material attribute setting on the grid structure generated through the ICEM based on Fluent; setting boundary conditions of the model structure and the grid based on Fluent; carrying out subsequent processing based on Fluent; the invention provides a coating spray booth airflow velocity and pressure simulation method, and provides a means for inspecting a design structure for a designer. Porous medium parameters adopted by simulation are equations fitted by curves obtained by multiple simulation results, and the obtained inertial resistance coefficient and viscous resistance coefficient results are more accurate; the structure can be quickly simulated and inspected for multiple times by modifying parameters; the change cloud picture of the speed and the pressure intensity of any surface can be obtained, the result is more intuitive, and a designer can conveniently refer to and change during design.

Description

technical field [0001] The invention relates to the field of airflow velocity and pressure simulation in a painting spray booth, in particular to a simulation method for airflow velocity and pressure in a painting spray booth. Background technique [0002] The flow of air in the painting booth has a great influence on the spraying effect of the car body. At present, the control of the airflow in the spray booth is generally adjusted by the experience of the designer and the project manager according to the specific situation on site, and cannot The structural design of the spray booth can be changed in time based on the airflow velocity and pressure of the intuitive three-dimensional model. This method will consume a lot of manpower, material and financial resources and is not easy to control. Therefore, it is very important to study a simulation method of air velocity and pressure in the spray booth for the design of the spray booth. Contents of the invention [0003] Th...
