VI-grade driving simulators help Goodyear enhance tyre product development
The Goodyear Tire & Rubber Company is using VI-grade driving simulators, including a dynamic model, to enhance its product development capabilities.
Goodyear has selected a Compact Simulator recently delivered to the company’s innovation centre in Luxembourg and a Dynamic Driving Simulator – the DiM250 (Driver-in-Motion), which will be installed in Akron, Ohio, in the coming months.
The driving simulators will be used for virtual development and tuning of dynamic performances of tyres, aided by the ability to simulate a range of driving conditions. They will also allow Goodyear to work more collaboratively with automobile manufacturers on original equipment fitments.
The Compact Simulator provides all the main features of VI-grade driving simulators in a reduced space. It features a driver’s seat, a fully-adjustable steering wheel, dashboard, pedals, gear stick and screen. The simulator is suitable for automotive OEMs that wish to prepare models to be used for a more advanced simulator (both Static and DiM) and that need to quickly test specific components. It is useful for Tier 1 suppliers who need to make sure that their components will work well when inserted into a more complex vehicle model. This kind of simulator can also be used by universities and research centres to develop and test dedicated control algorithms, as well to expose their students to driving simulator technologies.
DiM is a family of turn-key, yet open driving simulation solutions from VI-grade, which provides automotive engineers with a complete set of integrated driving simulators for a new generation approach to system-level simulation, allowing companies to bridge the gap between testing and simulation. The DiM solution is based on a patented revolutionary design with nine actuators. The resulting configuration with its 9 degrees of freedom enables to go beyond the basic six-actuator design of a simple hexapod or similar, thus providing a larger workspace while maintaining a high stiffness. This leads to a system suitable for low as well as high frequencies, both of which occur in automotive chassis design. For this reason, DiM enables to investigate vehicle dynamics as well as ride and comfort on the same driving simulator.
The DiM150, which is installed at leading automotive OEMs, motorsport teams and engineering service providers, is a driving simulator for integrated active / passive vehicle dynamics and ride development, as well as for ADAS and NVH applications. The DiM architecture captures low and high frequency performance for combined dynamics. The DiM250 features the same architecture and performance as the DiM150, but with extended linear actuators for increased travel of the tripod. This motion platform is suitable for applications which require longer time exposure to steady state accelerations. The longer time exposure corresponds to larger platform movement to cover the driver reaction time.
Driving simulators are beneficial for companies like Goodyear, because they allow to develop, test and validate tyre models early in the development cycle, enabling to identify the best performing tyres before building the first prototype. Thus, they enable to cut development costs and to keep the pace with the automotive development process, providing tyre models at the right time when requested by OEMs
