Revolute joints with clearance in multibody systems

Revolute 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...

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...

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...

A Compliant Measuring System for Revolute Joints with Clearance

This paper suggests a simple yet efficient experimental method to record the displacement of the shaft in a revolute joint with clearance. Two light and compliant cantilevers have been mounted on the rocker, each being instrumented with two strain gauges which can measure bending. These cantilevers are mounted in an orthogonal fashion, near the axis of the revolute joint, each touching the shaf...
