The mobile machine industry is well-known for the development of complex mechatronic products. Additionally, low output volumes and a large number of product variants emphasize the requirement of a highly efficient product development process. In recent years, the virtualization of product design has turned out to be a key factor for reducing development time and costs. Especially for cross-company engineering, the development of virtual products by using a coupled simulation represents a promising approach. However, co-simulation has not been established as a common method on this market yet, there are still many challenges to take. In the project GUSMA, these challenges are accepted and an effective solution is developed.
