Abstract

The paper has discussed the effect of dynamic contact behaviour on dynamics characteristics and contact nonlinear frequencies of multibody systems with geometric, physical and load parameters and motion conditions. In the work presented, a linearization method for contact nonlinear frequencies of constrained multibody systems is investigated. The nonlinear equations of motion of multibody systems are expressed indirectly in terms of the variations of independent coordinates, velocities and accelerations. The Lagrange multipliers are eliminated to get linearized equations of motion. The simulation analysis of kinematics, dynamics and contact nonlinear frequencies of numerical examples have been solved simultaneously. It shows that the frequencies of multibody systems with dynamic contact behaviours are nonlinear, timevarying and periodic with the effect of load-deformation factor, contact stiffness, load, motion conditions and initial conditions. This linearization method is available to research the contact nonlinear frequencies of rolling bearings
