Optimizing and safeguarding vehicle functions through simulations during the design phase
Daimler AG is one of the world’s most successful automotive companies. With its divisions Mercedes-Benz Cars, Daimler Trucks, Mercedes-Benz Vans, Daimler Buses and Daimler Financial Services, the Daimler Group is one of the biggest producers of premium cars and the world‘s biggest manufacturer of commercial vehicles with a global reach. In the development of new vehicle and drive concepts Daimler Trucks has been counting on ITI simulation solutions for many years. One of the latest applications is the design of pneumatic brake systems by using dynamic simulation.
In heavy-duty trucks the pneumatic system provides, amongst others, the energy for the braking system, the air suspension of the vehicle, the cabin, and the gearbox.
The behavior of the equipment is defined by various factors, such as the position of the components, the installable air reservoir volume and the pipe layout, while the components in turn are determined by the vehicle packaging. Daimler’s development team strives to optimize all vehicle functions already at early development stages. For new and further developments of commercial vehicles, engineers need to be able to make accurate predictions about the behavior of the pneumatic system, especially of the brakes, prior to building a physical prototype. The final results are important for the system layout and the dimensioning and positioning of the components in order to guarantee the optimal design for the pneumatic system.
