Dynamics of Multibody Systems With Spherical Clearance Joints [PDF]
Journal of Computational and Nonlinear Dynamics, 2005 This work deals with a methodology to assess the influence of the spherical clearance joints in spatial multibody systems. The methodology is based on the Cartesian coordinates, with the dynamics of the joint elements modeled as impacting bodies and controlled by contact forces. The impacts and contacts are described by a continuous contact force model
