A pre-conditioned method for the dynamical simulation of coupled mechanical multidoby systems

In the integrated design of complex technical systems the coupling of highly developed specialized simulation tools gets more and more important (co-simulation). The associated mathematical problem are coupled differential equations that have to be solved numerically. In the present paper we consider a waveform relaxation method for coupled mechanical multibody systems and use a pre-conditioner to guarantee convergence. The method has been applied successfully to the coupled simulation of pantograph and catenary
