"IC.IDO" is a VR tool that enables real-time verification of the product development process through virtual error detection. VR has already entered the "implementation" stage after going through the phase of being a "promising emerging technology," and its utilization in the product development processes of the manufacturing industry is progressing. Additionally, as remote meetings become more common, communication tends to become "sparse." By utilizing this tool, it is expected that "close" communication can be achieved even from remote locations. An online seminar will be held on January 27, 2022. Volvo Group Trucks will demonstrate how they are using this tool to reform their product development process aimed at achieving zero prototypes in a collaborative virtual workspace. ★ The seminar content will be available for on-demand viewing. If you are involved in design and manufacturing or responsible for DX, or if you are interested in industrial VR, please take this opportunity to watch. 【How to View】 Please check the details on the "ESI IC.IDO Blog" after January 28, 2022 (Friday).

In recent years, due to the influence of weight reduction and efficiency improvements, the design and material technologies of automotive components have become increasingly advanced, making considerations such as "how to enhance product performance during the manufacturing process" increasingly important. However, in actual manufacturing processes, products are produced through multiple processes, yet many CAE analyses focus solely on a single process or physical phenomenon. ESI Group proposes to replicate and predict design and manufacturing processes that include multiple processes, challenging to reduce lead times and costs through virtual prototyping. 【Case Studies】 ■ Fatigue durability analysis considering the casting process By faithfully modeling the pressing, welding, and press-fitting processes and transferring the residual stress and strain from each process, we evaluate the impact on the final fatigue strength performance. ■ Impact analysis considering the die-casting process The strength of die-cast products decreases in proportion to the amount of surface oxides entrained during filling. By providing material strength corresponding to the amount of entrainment calculated from die-casting simulations and conducting impact simulations, we achieved a good correlation with actual machine tests. *For more details, please refer to the PDF document or feel free to contact us.

I would like to introduce the current situation regarding updates on coupled analysis with VPS (Virtual Performance Solution). In the GUI, we create models for coupled analysis using ESI Group's integrated GUI environment, VE (Visual Environment), specifically Visual-Systems. With the release of VE 13.5, the number of available components has increased. Specifically, in the previous version, the outputs from the VPS model were limited to position, displacement, angle, and angular velocity. However, in the current version, it now supports displacement and load, and the outputs to the VPS model have expanded to include not only load and pressure sensors but also displacement, velocity, and moment. This significantly broadens the range of cases for conducting coupled analysis. *For more details, please feel free to contact us.*

This is a case study of a company that develops and manufactures propellers for ships. We provide details about the introduction of the COMPOSITES/PAM-RTM module and its effects. Initially, we managed with "experience and intuition." However, as orders increased and the size of the propellers we manufactured grew larger, it became difficult to cope with just experience and intuition. Therefore, we decided to introduce simulation software to replicate the infusion molding process within the computer, shifting our approach to conduct trial and error as much as possible within the computer. We compared several candidate products, but PAM-RTM stood out for its ability to support not only injection molding but also 3D VaRTM molding simulation, so we adopted it. *For more details, please download the PDF or contact us.*

At ESI, engineers with specialized knowledge for each production process use optimal tools to provide consulting services and contract analysis. ■□■ Heat Treatment and Welding Analysis Engineering ■□■ Applying heat to components through processes like welding and heat treatment for the purpose of metal bonding and material modification is a widely adopted technology. However, it is undeniable that the current situation relies on the experience and intuition of engineers. ESI proposes shortcuts to problem-solving using its cutting-edge analysis technology. ■ Heat Treatment Deformation Prediction It is possible to analyze various behaviors caused by the heat treatment process by considering phase transformations and the mechanical properties of temperature-dependent materials. ■ Welding Condition Optimization With the heat source model creation capabilities of ESI's 'SYSWELD' and its extensive track record, it is possible to predict all phenomena occurring during welding. ■ Welding Deformation Prediction Contributes to the optimization of welding paths and constraints.
