The purpose of the present study is to investigate the Correlation of gas penetration／permeation to structure performance in gas-assisted injection inolded parts. Meanwhile, the accuracy and the applicability of ANSYS 3D and 2D model for the analysis of part structure performance. And make analysis of the gas-assisted monitor supporter.
From the present study, the following conclusions have been found:
Gas penetration／permeation to structure performance in gas-assisted injection molded parts have not obviously stress concentration effect. From bending experiment, the relationship between bending stiffness and moment of inertia is linearly. The relationship between Maximum bending load and section module is also. From bending experiment, the break is not occur at the end of gas-penetration. The hollowed shape is the most important reason. Gas penetration／permeation to structure performance in gas-assisted injection molded parts is not have the CAE simulation using ANSYS to analyze part structure characteristics in both two dimension and three dimension models show that the error between the predicted value and experiment''s results can be acceptable. The trends among experiment results, three dimension and two dimension are the same. Different injection molded method can change the Young''s module.
Because of simply model, the error of 2D analysis is higher the 3D. But using 2D analysis can save the cost of computation efficiently, and the trends between 2D and 3D analysis results the same.
From present study, can offer the gas channel design on the parts structure characteristic.
