Dynamic Feedforward Control of a Novel 3-PSP 3-DOF Parallel Manipulator
parallel manipulator dynamic feedforward control high-speed hybrid machine tool
2011/8/4
Parallel manipulators with less than six degrees of freedom (DOF) have been increasingly used in high-speed hybrid machine tools. The structural features of parallel manipulators are dynamic, a charac...
The Variation of the Friction Coefficient in Pipe Connections Working Under Static and Dynamic Loads
Galling Time Dependent Friction Coefficient Lubrication
2009/10/14
The friction coecient and the galling process in metal to metal parts depend on many variables such as normal load, lubricant, roughness and design of the friction surfaces. Since developing a mathem...
Two Different Methods to Investigate Dynamic Motion of Flexible Link That Rotates About Fixed Axes
Flexible Link Assumed Modes Lumped Parameter
2009/10/14
In this study, assumed modes and lumped parameter methods are used to investigate the transversal
vibrations of a flexible beam rotating around a fixed axis. Equations of motion are solved by using t...
A Nonlinear Torsional Dynamic Model of Multi-Mesh Gear Trains Having Flexible Shafts
Gear HBM Multi-mesh Time-varying
2010/1/14
A non-linear time-varying dynamic model is developed to study torsional dynamic behavior of a typical multi-mesh gear
train. The physical system consists of M shafts (M ≥ 2 ) coupled to each other by...
