DYNAMICS OF THE 3-PRP PLANAR PARALLEL ROBOT
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2009, Vol 54, Issue 2
Abstract
Recursive modelling for the kinematics and dynamics of the 3-PRP planar parallel robot is established in this paper. Three identical planar legs connecting to the moving platform are located in a vertical plane. Knowing the motion of the platform, we develop first the inverse kinematics and determine the positions, velocities and accelerations of the robot. Further, the principle of virtual work is used in the inverse dynamics problem. Several matrix equations offer iterative expressions and graphs for the powers of three prismatic actuators. The study of the dynamics of the parallel mechanisms is done mainly to solve successfully the control of the motion of such robotic systems.

USE OF GENETIC ALGORITHMS FOR FITTING THE BOUC-WEN MODEL TO EXPERIMENTAL HYSTERETIC CURVES
In this paper a Genetic Algorithms (GA) method is developed to identify the Bouc-Wen model parameters from the experimental data of periodic loading tests. It is considered an extension of classical model in order to inc...
A SPECIAL CLASS OF DRIP MEDIA WITH HYSTERESIS
Since the interaction phenomenon for waves of arbitrary shape and amplitude is a property of the transmitting medium rather than of the particular wave profiles, Seymour and Varley named as DRIP the media that do not rem...
