Case Study of the Structural Analysis Solution 'VPS' by the Railway Technical Research Institute
Precisely reproducing smooth tooth surface contact! Utilizing VPS for railway noise sources and their countermeasures!
The Public Interest Incorporated Foundation Railway Technical Research Institute is a research organization that was established in 1987, inheriting operations from the former National Railways' Railway Technical Research Institute and others. The organization has been conducting simulations of vehicle collisions and other scenarios for many years, primarily using the "Crash module" of the VPS. In recent years, in addition to this, they have also been working on contact system analysis of gears, rails, and wheels using the "Medysa module," and it has been applied to vibration and noise issues of gear devices with a parallel cardan system. Understanding the phenomenon of gear noise and elucidating its propagation mechanisms are limited experimentally and can be costly, making simulation a useful tool. 【Benefits of Implementation】 ■ Can precisely reproduce smooth tooth surface contact ■ The Crash structural analysis module is compatible with other VPS modules ■ When calculating in an integrated environment, if you have VPS data, it can be applied elsewhere *For more details, please refer to the PDF materials or feel free to contact us.

Company information
ESI Group is a leading company in "virtual prototyping," providing innovative solutions and services that emphasize "materials physics." We have developed unique solutions that enable the replacement of physical prototypes and experiments with virtual design, manufacturing, assembly, testing, and evaluation. Leveraging today's cutting-edge technology, ESI's virtual prototyping addresses the challenge of performance evaluation throughout the product lifecycle, from the start of use to the end of life, proposing a broader concept: Product Performance Lifecycle (TM). This is achieved by creating a Hybrid Twin (TM) that utilizes simulation, physics, and data analysis, allowing for smarter product development, maintaining a connection with the actual product, and enabling performance predictions and maintenance timing throughout the product's usage period.
