A Kriging Model for Dynamics of Mechanical Systems With Revolute Joint Clearances

A Design of Experiment and Kriging-based Model for Studying the Dynamics of Multibody Mechanical Systems with Revolute Joint Clearance

Spatial revolute joints with clearances for dynamic analysis of multi-body systems

This paper presents a new technique for assessing the influence that clearance of spatial joints has on the kinematics and dynamics of multi-body systems. The technique is developed for the revolute joint in which the basic elements are the journal and bearing. Under certain working conditions, these two mechanical elements collide with each other being the contact treated as coupled forces. Th...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Systems Dynamics Model for Project Management systems of Project-Based Organization

It is obvious that the success of a project-based organization is dependent on its projects. A variety of tools such as the project excellence model, project management maturity models, the earned value method, have been developed in this regard, but there are still delays in projects because the projects have dynamic nature with non-linear relationships and feedback processes during the projec...

Dynamic Behavior Analysis of a Planar Four-bar Linkage with Multiple Clearances Joint

 In practice, clearances in the joints are inevitable due to tolerances, and defects arising from design and manufacturing. In the presence of clearance at a joint, a mechanism gains some additional, uncontrollable degrees of freedom which are the source of error. Moreover, joints undergo wear and backlashes and so cannot be used in precision mechanisms. In this study, the dynamic behaviour of ...
