Resolution of Constraint Equations for Real-Time Model of Vehicle Suspension

Kurzfassung

This paper presents one of the approaches for the reduction of suspension models containing kinematic closed loops for real-time simulation. The model reduction is based on the ODE formulation of the equations of motion in the independent coordinates together with subsystem-local solution of constraint equations describing kinematic loops. Furthermore, different methods for formulating the constraint equations are mentioned. The implementation of the reduction technique in the multibody simulation package SIMPACK and some simulation results are presented as well.
