Dynamics of Multibody Systems

Railway Vehicle Dynamics, Multibody Systems, and Bifurcation Analysis

DLR’s Vehicle System Dynamics group has a long tradition in the computational analysis of railway vehicles’ dynamics. The group’s main focus used to be on the development of software tools for the efficient analysis of general mechanical systems with a special emphasis on the dynamics of ground vehicles like automobiles, railway vehicles and aircraft landing gears. The respective research activ...

Symbolic Modeling and Analysis of Elastic Multibody Systems

The algorithms to set up the equations of motion symbolically for both rigid and elastic multibody systems are presented. In the described program Neweul-M which is using the power of Matlab and Maple, the modeling approach with commands and a graphical user interface are discussed as well as an overview of possibilities for system analysis, control design and optimization is given. A double pe...

The Comparison of Direct and Indirect Optimization Techniques in Equilibrium Analysis of Multibody Dynamic Systems

The present paper describes a set of procedures for the solution of nonlinear static-equilibrium problems in the complex multibody mechanical systems. To find the equilibrium position of the system, five optimization techniques are used to minimize the total potential energy of the system. Comparisons are made between these techniques. A computer program is developed to evaluate the equality co...

Reliability analysis of repairable systems using system dynamics modeling and simulation

Repairable standby system’s study and analysis is an important topic in reliability. Analytical techniques become very complicated and unrealistic especially for modern complex systems. There have been attempts in the literature to evolve more realistic techniques using simulation approach for reliability analysis of systems. This paper proposes a hybrid approach called as Markov system ...
