Yamaha Motor has used CAE for many years to address development issues, and positioned it as a point solution.

Under the recent circumstance of global environmental changes represented by CN(carbon neutral), CAE is being regarded as an important tool for development ability,; in this presentation, the cases of efforts to improve the environment for utilizing CAE were presented.

・Mr. Minabe, Yamaha Motor Co., Ltd.

Polyplastics Co., Ltd. deals in resin molded products. Voids may form near thick sections of resin products depending on the molding conditions and product shape, which affect products’ lifespan depending on their position and size. Recently, with the popularization of non-destructive observation equipment such as X-ray CT, it has become more easier to detect voids, and there is an increasing demand to control them. This presentation introduced a case of technology for predicting void control effects due to product thickness and gates runners by using ADVENTURECluster.

・Mr. Kobayashi, Polyplastics Co., Ltd.

The quality of casting products is greatly affected by the mold temperature. By reproducing the actual mold temperature in the analysis, it is possible to solve problems through feedback analysis. Honda Foundry Co., Ltd. achieved highly efficient analysis by automating heat transfer calculations using ADVENTURECluster.

This presentation introduced the coupling analysis case of heat transfer calculations using the numerical optimization software modeFRONTIER and ADVENTURECluster.

・Mr. Watanabe, Honda Foundry Co., Ltd.

Toyo Seikan Group Holdings, Ltd. uses ADVENTURECluster to analyze the bending and closing of hinge caps. Since the hinge is subject to large deformation, the calculation is prone to divergency.

Therefore, it took a lot of effort to create the elements of the hinge, and the ‘u-p formulation’, based on a mixed method that solves nonlinear equations using hydrostatic stress (pressure) as an independent variable in addition to displacement, was adopted.

As a result, the initial hinge shape, which had poor fitting, was improved and the fitting condition was also improved,which was introduced in the case.

・Mr. Washizaki, Toyo Seikan Group Holdings, Ltd.

In recent years, maintaining and managing social infrastructure facilities such as roads and bridges has become a social issue due to aging and a declining working population.

Toshiba Corporation has constructed a large-scale analysis model of an existing bridge towards the goal of realizing a bridge digital twin.

This presentation introduced a case that the existing bridge was precisely reproduced entirely to achieve a highly accurate response, and the deformation behavior of a long-span bridge was successfully reproduced, which could not be reproduced with conventional models.
