Improvement of Random Surface Modeling Method with Deviation Using DTCWT

Abstract

The general mechanical parts have small irregularities on the surface and the potential to affect the assembly of the products. In mechanical design of robots, mobility, and home appliances, surface features related to mechanical function are more essential elements. The products development process should be shortened in the product development field because problems in product development is the increase of time and cost due to the improvement of quality. Therefore, CAE simulations have been conducted at the design stage using ideal surface topography without surface irregularities and deviations. In this study, the multiscale method we have developed in previous study was improved to generate more realistic surface model. The generated surface models were compared with actual machined surfaces based on surface profile parameters.
