Geometric modeling and rational analysis of multilayer single channel finite element based on isosceles trapezoidal section
Multilayer single channel finite element coupled thermal-mechanical modeling method based on isosceles trapezoidal cross section was proposed.Firstly,a multi-layer single-channel trapezoidal function model was built on a single-layer single-channel isosceles trapezoidal function model.Then,rationality of multi-layer single-channel trapezoidal function model was verified by comparing geometric deviation and thermal performance indexes of multi-layer single-channel trapezoidal function model and parabolic function model,and thermal coupling simulation analysis and corresponding experimental verification of multi-layer single-channel deposition process were carried out.The simulation and test results showed that simulation results of multilayer single-channel trapezoidal function model were in good agreement with parabolic function model and test results,and computational efficiency was improved to a certain extent.
