先端力学シミュレーション研究所 List of Products and Services

We would like to introduce a CAE solution case using the structural analysis software 'ASU/V-Struct' for resin sheet press molding. In automotive interiors, such as headliners, there are many instances where composite materials centered around resin are formed by pressing. During these molding processes, similar to metal pressing, defects such as cracks and wrinkles can occur, and adjusting molds and molding conditions through trial and error can require a significant amount of time and effort. By using simulations, it is possible to predict molding defects and shorten development periods. For more detailed case information and about our products and services, please refer to the PDF materials. [Case Overview (Partial)] ■Challenges - We would like to consider measures for molding defects such as cracks and wrinkles. - We would like to explore methods for securing the sheet during pressing. - We would like to investigate the deformation of the sheet and the timing of contact with the mold. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a CAE solution case using the structural analysis software 'ASU/V-Struct' for visualizing vacuum/pressure forming. In vacuum/pressure forming, heated resin sheets are pressed against molds for shaping. As a result, variations in the thickness of the molded products are likely to occur, and if the thickness becomes extremely thin, issues such as insufficient strength arise, leading to defective products. Additionally, defects such as wrinkles on the molded products can occur. If such problems can be identified and addressed in advance through analysis, it can reduce rework related to defects and help control labor costs. We provide detailed information about our products and services in a PDF document, so please take a look. 【Case Overview (Partial)】 ■Challenges - Unable to predict the thickness of the molded products - Want to understand how the material adheres to the mold - Defective products have emerged, and we want to investigate/improve *For more details, please download the PDF or feel free to contact us.

In this document, we introduce a case study of the contact analysis of three deformable bodies, specifically focusing on "crimping of hoses." In molding that combines multiple parts, it becomes necessary to calculate the contact between the deformable bodies in order to observe the deformations of the various parts. Our "ASU/V-Struct" is proficient in analyzing such deformable body contacts and can stably solve problems that do not converge with conventional static implicit methods. We have included an overview and analysis examples related to crimping, along with diagrams, making it easy to reference during the consideration of implementation. We encourage you to take a look.

We would like to introduce a case study of the implementation of the structural analysis software 'ASU/V-Struct' at Kawanishi Industrial Co., Ltd., a global comprehensive manufacturer. At the company, due to the viscoelastic nature of the headlining (ceiling material) molding, it was difficult to make predictions through simulations, resulting in significant time and costs for evaluations using actual parts, which posed challenges to development speed. After the implementation, factors related to moldability were identified, and pre-simulation evaluations became possible, leading to a significant improvement in production stability, with almost no need for rework after molding. Details of the expected effects of CAE and the development overview can be found in the PDF document, so please take a look.

In the current press forming simulation, the mold is treated as a rigid body, and deflection is not taken into account. However, during actual press processing, especially when forming high-strength steel plates, a very large load is applied, resulting in mold deflection. This causes changes in the clearance between the upper and lower molds, leading to variations in contact and surface pressure on the workpiece depending on the location. Additionally, the amount of deflection varies based on the structure of the mold. To reproduce the phenomena of actual press processing in press forming simulation, an analysis that considers mold deflection is necessary. We will introduce a case of forming simulation that takes mold deflection into account using the open-source structural analysis software FrontISTR for mold deformation and our solver ASU/P-form for weakly coupled analysis. ASU/ISTR is a general-purpose pre- and post-processing software developed by our company that is compatible with FrontISTR. By utilizing the deflection weakly coupled setting function of ASU/ISTR, we can quickly incorporate the analysis results from ASU/P-form and automatically set the conditions. Furthermore, it allows for easy analysis setup and execution on a Windows PC. FrontISTR excels in parallel computing, and there are no licensing costs even when using a PC with a high number of cores.

Fuel Cell Vehicles (FCVs) are expected to provide clean and sustainable mobility through the use of hydrogen, enabling rapid refueling and long-distance travel with zero emissions. The tanks designed to safely store high-pressure hydrogen are extremely important components for FCVs, but overcoming many challenging issues such as weight reduction and cost reduction is necessary for widespread adoption. ASU/FrontCOMP is an analytical tool developed for the design of high-pressure vessels for FCVs. ■ To reproduce the complex stress state within CFRP products, a mesoscale model that directly models the fiber bundle shape is required. ■ A 3D analysis model of the CFRP layers modeled from the liner and fiber bundles of Type-IV pressure vessels will be created within practical timeframes. ■ Detailed analysis using a fiber bundle embedding model and pseudo-mesoscale analysis using a fiber bundle mapped model are possible. An FEM analysis model that reproduces the design requirements of CFRP pressure vessels can be easily generated. The fiber bundle mapped model also supports input and output in FrontISTR (free) format, which can reduce the licensing costs for large-scale computation execution. In Ver.6, parallelization of the model generation process has been implemented, significantly shortening the generation time.
