Transnet Freight Rail predicts wheel wear with VI-grade railway solutions
VI-Rail is the specialized railway simulation software from VI-grade. VI-Rail enables to quickly build a complete, parameterized model of a new railway vehicle, easily define its suspension, wheelset, wheel-rail contact, and other vital characteristics. Running through a battery of simulations it is possible to determine the vehicle’s stability, derailment safety clearance, track load, passenger comfort, and more. The performance of a railway vehicle design can be optimized virtually in the computer, before cutting a single piece of metal or running a single physical test. VI-Rail users can instantly see the effects of design changes on railcar performance in high-speed animation, easily detecting component interferences, excessive wear, instability, and performance limitations. Users can also plot key parameters in graphs to compare results from different designs.
VI-grade successfully completes installation of DiM Driving Simulator at Volvo Car Corporation
The 9 degrees-of-freedom DiM® platform has been designed in order to take full advantage of VI-MotionCueing as well as of all other software technology developed by VI-grade and its partners. The DiM® concept enables the extension of the motion envelope and the separation of low and high frequency contributions, which makes this type of motion platform unique and suitable for both vehicle dynamics and ride studies.
“The DiM complements our tool chain and allows us to physically experience our simulation models using human test drivers” says Carl Sandberg, Vehicle Dynamics Concept Engineer at Volvo Car Corporation. “The simulator emphasizes the human centric approach Volvo is known for, allowing driving dynamics and active safety systems to be experienced in a realistic environment right from the start of the development process.”
“We are extremely happy to report this commercial success at Volvo Car Corporation”, said Guido Bairati, Sales Director, VI-grade. “Together with our sales representative in Sweden CAE Value, with technical partner Saginomiya and other technology vendors like Concurrent, Sim.Co.VR, Barco, VIRES and Imtec we have installed this complex vehicle simulator as a turn-key solution at the Volvo premises.

Showa Corporation implements a top-notch steering simulator with new variable damper based on VI-grade technology
The advanced simulator, based on the VI-CarRealTime and VI-GraphSim software solutions installed on RedHawk technology, has been used since its launch in 2014 to evaluate the performance of electric power steering (EPS) systems in early stages of the development process. In addition, the steering simulator has been used to develop and finetune a cooperative control model in conjunction with a revolutionary variable damper model. This model, based on a theoretical approach property of Showa, estimates the vehicle states using the wheel velocity instead of sensors, enabling to obtain dramatic improvements (also in terms of weight of the damper component) with respect to the usage of a conventional variable damper.
Showa Corporation widely utilizes software products such as VI-CarRealTime, VI-Motorcycle and VI-GraphSim as well as professional support from VI-grade in the development process of their new products for the automotive and the motorcycle racing industries - for example new variable dampers and new EPS steering systems. The software solutions are also used for MOTO GP racing studies.

VI-grade Supplies MRacing Formula SAE Team with a COMPACT Simulator
Marburg, July 21st, 2015 – VI-grade today announced that the MRacing Formula SAE Team of the University of Michigan has adopted VI-grade's COMPACT Simulator. In detail, the simulator will be used to support chassis and controls development for formula SAE vehicles.
“We have already put in many hours on tuning our VI-CarRealTime model, which creates a significant advantage as we move to the next level: using VI-DriveSim” said Peter Karkos, 2016 MRacing Technical Director. “The main value from the adoption VI-grade's COMPACT Simulator in our team comes from the potential time that will be saved through physical testing of different suspension setups, aero packages, drivetrain packages, etc. In addition, the relatively low-cost of setting up the system is perfect for our situation of being a college race team.”
“The most important feature is our ability to quickly correlate the computer model to our real-life vehicle by having a driver be able to give immediate feedback. It can eliminate months of tedious tests, and will allow for rapid improvements once we have an accurate model” added Karkos. “Additionally, the simulator enables our team to continue to develop the vehicle and have drivers learn how to drive it during the off-season. Due to the weather conditions, there are many months when our team cannot take the vehicle out for testing, so it is crucial to be able to virtually optimize the setup of our racing cars on the simulator in preparation for the upcoming FSAE competitions.”
“We are very excited about our continuous collaboration with the University of Michigan,” said Brian Cheung, Director of System Level Simulation Inc. “Major racing teams in all series are using vehicle simulation of all kinds to increase competitiveness in an environment with less physical testing and demands for more performance, and we are looking forward to further supporting the success of the MRacing team.”
