Internal dynamics of multibody systems

An Efficient Multibody Dynamics Model for Internal Combustion Engine Systems

The equations of motion for the major components in an internal combustion engine are developed herein using a recursive formulation. These components include the (rigid) engine block, pistons, connecting rods, (flexible) crankshaft, balance shafts, main bearings, and engine mounts. Relative coordinates are employed that automatically satisfy all constraints and therefore lead to the minimum se...

Formulation of Dynamics for Serial Rigid Multibody Systems

There has been a growing interest in the development of new and e cient algorithms for multibody dynamics in recent years. Serial rigid multibody systems form the basic subcomponents of general multibody systems and a variety of algorithms to solve the serial chain forward dynamics problem have been proposed. In this paper, the economy of representation and analysis tools provided by the spatia...

Dynamics of Multibody Systems With Spherical Clearance Joints

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 that accounts for geometric and mechanical...
