Analyze Thickness Precision of Irregular Metal Aerosol Can Based on ANSYS

摘要

Irregular metal aerosol can should not only satisfy consumer's individual demand, but also reduce thickness as much as possible with long-term pressure resistance. In this study, three difference can structures are designed with ergonomics considerations. SolidWorks software is adopted for modeling and ANSYS for simulation and analysis. The relevance between can thickness as well as long-time pressure resistance is discussed. The thickness of the shell is set to 0.45, 0.50, 0.55, 0.60, and 0.65 mm, respectively. The models from SolidWorks are then imported into ANSYS and 1.2 MPa pressure is imposed from inside wall. Based on the resulted curves of thickness stress, an optimum thickness is obtained for each can. Combined with aesthetics and ergonomic factors, the third model is considered to be the best design, with a maximum stress value of 707.8 Mpa in 0.51 mm thickness. It is less than the standard 720.0 Mpa and verified on remodeling of the third model. Summarily, this discussion aims to improve the design accuracy and provide a profit basis.
