Increasing automation at all system levels and the fact that vehicle development nowadays takes place across companies and in development and supplier networks require a highly efficient product development process. Co-simulation is an important tool for this. The aim of the Gusma joint project carried out at KIT is therefore to make co-simulation usable for cross-company simulation in the off-road sector. |

Summary Simulation is playing an increasingly important role in the development process of mobile machinery. Complex systems consisting of mechanics, hydraulics and control must be mapped. The simulation programs available today only offer the possibility of completely mapping these systems with one program to a limited extent. In addition, it is possible to use a specialized program for each discipline and connect them by means of a so-called co-simulation. Numerous programs already offer such interfaces, but there are still various difficulties to overcome, especially when integrating complex hydraulic systems. The GUSMA project aims to develop the basic principles and demonstrate the application of co-simulation using a typical example of controlled comfort hydraulics. The process of co-simulation is to be standardized and a platform established on which the coupled simulation can be carried out using a standardized procedure. In order to expand the close supplier relationship that has developed, which is typical for the mobile machinery sector, the possibility of integrating partial simulation models from the supplier into the overall model is to be created. Particular attention must be paid to the issue of know-how protection. |

| Cross-company simulation of mobile machinery - A proposal for a standardized approach | 1. Commercial Technology Symposium 2010, Kaiserslautern |
Mobile machines are complex systems and represent a combination of many different engineering disciplines such as mechanics, hydraulics, pneumatics or control engineering, the interaction of which makes the performance and functions of such a machine possible in the first place. This interaction complicates the simulation of such machines. This article therefore presents a proposal for a standardized procedure that can be used to simulate a mobile machine across company boundaries. The basis for this is the idea of a platform on which the simulation is to be carried out. |

| Efficiency Optimisation of Tracked Vehicles Using Secondary Control in a Single-Circuit Load Sensing System | Beitrag zu „7th International Conference on Fluid Power (IFK)“ |
Abstract The paper describes a concept of a secondary controlled traction drive integrated in a common Load Sensing system. When used in a single circuit system, a secondary controlled drive for tracked vehicles shows a big efficiency optimisation potential compared to other drives. The high losses at turns can be avoided if two secondary controlled units are connected to a single Load Sensing valve. The traction drive is still supplied in a traditional way using Load Sensing. For steering, the secondary controlled units are integrated in a control loop where the steering ratio is used as command value. |

| Investigation of the communication interval in the coupled simulation | Karlsruher Schriftenreihe Fahrzeugsystemtechnik / Institut für Fahrzeugsystemtechnik ; 6 ISSN: 1869-6058 |
Abstract Coupled simulation is a way of mapping mechatronic systems in simulation. This paper describes coupled simulation under Matlab/Simulink and shows a way of determining the communication interval in coupled simulation, taking into account the subsystems involved. The developed action specification is verified using examples from the field of mobile machinery. |
