Modelling lubricated revolute joints in multibody mechanical systems
This work deals with the modelling of lubricated revolute joints in multibody mechanical systems. In most machines and mechanisms, the joints are designed to operate with some lubricant fluid. The high pressures generated in the lubricant fluid act to keep the journal and the bearing apart. Moreover, the thin film formed by lubricant reduces friction and wear, provides load capacity and adds da...
متن کاملRevolute joints with clearance in multibody systems
A computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented in this work. Clearances always exist in real joints in order to ensure the correct relative motion between the connected bodies being the gap associated to them a result of machining tolerance, wear, and local deformations. Clearance at different joints is the source for impact fo...
متن کاملDynamic Analysis for Planar Multibody Mechanical Systems with Lubricated Joints
The dynamic analysis of planar multibody systems with revolute clearance joints, including dry contact and lubrication effects is presented here. The clearances are always present in the kinematic joints. They are known to be the sources for impact forces, which ultimately result in wear and tear of the joints. A joint with clearance is included in the multibody system much like a revolute join...
متن کاملNonholonomic Motion Planning for Coupled Planar Rigid Bodies with Passive Revolute Joints
Motion planning for coupled rigid bodies in a horizontal plane is investigated. The rigid bodies are serially connected by passive revolute joints. The dynamic constraints on the system are second-order nonholonomic constraints. We attempted to control those n coupled rigid bodies by the translational acceleration inputs at the first joint. If each rigid body is hinged at the center of percussi...
متن کاملIterative Rigid Multibody Dynamics
The simulation of large rigid multibody systems is a challenge. Collisions and friction constraints cause non-smooth motions of the rigid bodies. Differential complementarity problems are therefore used to formulate the dynamical system. The efficient solution of such problems is difficult and the major focus of this thesis. Several modeling choices of varying accuracy and difficulty are presen...
