Accurate and up to date information from bearing suppliers at your fingertips, right from the first concept sketch and the initial bearing selection, all the way through to the final cut. Meaning accurate calculations, and your best chance for an optimized design with a scalable supply chain.
NACHI-FUJIKOSHI was founded as a tool manufacturer in the City of Toyama in December 1928. Ten years after its founding, the firm set up a steel mill and established an integrated production system covering aspects from materials to the final product.
Through complex and linked Nachi Business – machining business with machining, robots, and the like, functional components business with bearings, hydraulic equipment, and the like, materials business with materials and heat treatment – the firm “Contributes to the development of the world of product manufacture.”
Synergy: Nachi’s bearing catalogue data is included in Romax software for accurate system analysis and detailed bearing analysis. This is available from the Romax cloud-based download system, so that your catalogs are always accurate and up to date.
Use structural response in acoustic analysis, and predict radiated noise, a key target metric for motor and gear whine.
VI-grade provides software products and services for advanced applications in the field of system level simulation. Together with a network of selected partners, VI-grade also provides revolutionary turn-key solutions for static and dynamic professional driving simulation.
Established in 2005, VI-grade delivers innovative solutions to streamline the development process from concept to sign-off in the transportation industry, mainly automotive, aerospace, motorcycle, motorsports and railways. With office locations in Germany, Switzerland, Italy, UK, Japan, China, and the USA, and a worldwide channel network of more than 20 trusted partners, VI-grade is a dynamic and growing company with a highly skilled technical team
Synergy: Meeting the sound quality requirements for an electric vehicles poses different challenges compared to vehicles with internal combustion engines. VI-grade’s NVH Simulators can be used to experience vehicle noise based on a combination of simulated and measured noise sources. Experiencing the noise through simulated driving provides greater insight into the vehicle interior noise quality allowing the effect of design changes to be considered before a real vehicle exists.
Romax and VI-grade have developed a process to perform an interactive evaluation of an EV virtual prototype using the VI-grade NVH Simulator. Together, we combined on one side, CAE simulation data to characterise the EV powertrain noise sources due to the electric motor and gearbox, and, on the other side, transfer functions measured on a surrogate vehicle to propagate the sound sources to the driver ears. We then demonstrate how to use this virtual prototype for interactive sound quality evaluation as you would do when driving a vehicle, but this is here performed even before having access to a physical prototype.
Process Integration and Design Optimisation Partners
Piecing together the elements of a combined process that potentially spans your entire department (and even beyond) is a full-time job. We have focused on solving the technical challenge this presents, so that you can focus on the bigger picture. A process, once automated, is ripe for exploring through design optimization software.
Combine Romax kinematic models and loss methods with CFD to analyse fluid distribution and churning loss early in the design process, for the whole transmission.
Multibody Dynamics, Engine and System Analysis Partners
There are many failure mechanisms to eliminate in the time domain. Choose the right tool for the job and drive it through Dynamic Fusion.
Structural FEA Partners
Combine FEA with Romax component models. Use Romax component models to feed accurate boundary conditions into FEA, and vice-a-versa.
The link between Design and Analysis has never been closer. Using our direct modelling CAD solution, we take 3D geometry, clean it up, mesh it, and combine it with our Romax component models. Going the other way, we take parametrically defined components and create 3D geometry for use as the basis for detailing work by the CAD team.
