The role of Computer Aided Engineering in vehicle development has been significantly increased during the last decade. Specialised simulation tools became very complex, however, growing demands on complexity and particularly interdisciplinarity of vehicles and their simulation models have led to a number of approaches trying either to develop multidisciplinary simulation tools or to connect various specialised simulation tools by interfaces. This paper addresses some aspects of interconnection of the specialised simulation tools as one possibility for simulating complex mechatronic vehicle systems. It classifies the interfaces between specialised software packages in general, mentions some historical development of the interfacing and further discusses the examples of the implemented couplings between the Multibody System codes and Computer Aided Control Engineering tools. Finally, the performance of selected interfaces is compared on an example simulation of a controlled vehicle suspension.

Overview of Coupling of Multibody and Control Engineering Tools

In order to take into account the interaction between the part, dynamic system, control system, and changing mechanical behavior with all its consequences for the optimization process, a simulation of the complete mechatronic system is integrated into the optimization process within the research work presented in this paper. A hybrid multibody system (MBS) simulation, that is a MBS containing flexible bodies, in conjunction with a cosimulation of the control system represented by tools of the computer aided control engineering, is integrated into the optimization process. By an inner optimization loop the controller parameters are adopted new in each of the iterations of the topology optimization in order to provide realistic load cases. The benefits will be illustrated by an example in conjunction with the humanoid robot ARMAR III of the Collaborative Research Centre 588 “Humanoid Robots-Learning and Cooperating Multimodal Robots” in Karlsruhe Germany. It will be shown how the new approach for the optimization of parts “within” their surrounding mechatronic system allows an efficient optimization of such structures.

Integrated Structural and Controller Optimization in Dynamic Mechatronic Systems

This paper reviews the state of the art in modeling and control of active and semi-active suspension systems. Distinctive characteristics are established for the major types of suspension systems: passive, active, and semi-active. Regarding modeling and simulation, different approaches, tools and applications are discussed in the context of vehicle dynamics. Besides, the quarter car model, which is widely used in research, is developed with differential equations, transfer functions, and state-space equations, as well as solutions for simulation in Simulink and SimMechanics. As for control of active and semi-active systems, the major strategies for vehicle suspension are reviewed. Furthermore, the paper outlines suspension control in other engineering applications.

Los Sistemas de Suspensión Activa y Semiactiva: Una Revisión

In der vorliegenden Arbeit wird ein neuer Prozess zur Optimierung von mechanischen Bauteilen in dynamischen und geregelten Systemen vorgestellt. Hierzu werden die Finite Elemente Methode, die Simulation von Mehrkorpersystemen und Regelungssystemen sowie die Topologieoptimierung genutzt. Durch die Integration dieser unterschiedlichen Analysemethoden konnen die Wechselwirkungen zwischen Bauteil, System und Regelung aktiv bei der Bauteilgestaltung einbezogen werden.

Topologieoptimierung von Bauteilen in dynamischen und geregelten Systemen. Topology optimization of parts in dynamic and controlled systems

With the development of humanoid robots, lightweight construction and energy efficiency play an important role. In state-of-the-art processes and methods concerning structural optimization it is assumed that there exists a set of external loads or load functions acting on the part. But humanoid robots are very complex mechatronic systems. The fact that the system's dynamic properties and its overall behavior may change due to geometric modifications of a part caused by an optimization process is typically neglected. In order to take into account the interaction between the part, dynamic system, control system and the changing mechanical behavior with all its consequences for the optimization process, a simulation of the complete mechatronic system is integrated into the optimization process within the research work presented in this paper. A hybrid multibody system (MBS) simulation, that is, a MBS containing flexible bodies, in conjunction with a co-simulation of the control system represented by tools of the Computer Aided Control Engineering (CACE) is integrated into the optimization process. By an inner optimization loop the controller parameter are adopted new in each iteration of the topology optimization in order to provide realistic load cases. The research work presented in this paper is a contribution towards the integration of existing CAE methods into a continuous process for structural optimization. The benefits will be illustrated by an optimization of parts of the humanoid robot ARMAR of the collaborative research centre for “Humanoid Robots”. The new process allows an efficient optimization of structures “within” their surrounding mechatronic system.

Integrated structural and controller optimization for lightweight robot design

Modeling and computer simulation play an important role in all engineering disciplines. As specialized simulation tools have become very sophisticated and, at the same time, the simulation of complex systems and phenomena showed the limits of mono-disciplinary approaches, multi-disciplinary simulation has gained wide acceptance. For the coupling of different simulation tools interfaces are necessary including both aspects of physics and numerics as well as of software engineering. With a great number of interfaces to other engineering disciplines multibody simulation (MBS) programs are true multidisciplinary tools which can be used from the pre-design phase to trouble shooting on a production vehicle. The presentation will start with a short introduction into multibody simulation, followed by a general classification of interfaces between simulation tools. As an example the MBS tool SIMPACK and its integration in the concurrent engineering loop including the interfaces to FEA, CAD, CFD and the control design engineering will be presented along with railway, automotive and aerospace applications.
