The driving stability of silo vehicles is significantly affected by the type of cargo that is transported and the design of
the tank. Cargo motion can have both beneficial and negative aspects in terms of driving stability and braking performance.
Neglecting the influence of the dynamically moving cargo in driving simulations of silo vehicles leads to significant errors
in the simulation results. We propose a new method for the dynamic simulation of silo vehicles carrying granulates. The method
couples Lagrangian particle methods, such as the discrete element method, and multibody systems methods using co-simulations.
We demonstrate the capability of the new approach by providing simulation results of two benchmark maneuvers.

Werner Schiehlen was educated as a mechanical engineer and received a Ph.D. on satellite dynamics in 1966. After working for 10 years with
the Technical University Munich and spending one year with NASA in the US he was appointed full professor of mechanics with
the University of Stuttgart until his retirement in 2002. He published more than 320 scientific papers in applied and computational
dynamics including 7 books mostly translated in foreign languages, too. Werner Schiehlen served as President of IUTAM. Since
1997 he is Editor-in-Chief of the international journal MULTIBODY SYSTEM DYNAMICS.
