Residual Vibration Suppression Using Simple Motion Trajectory for Mechanical Systems

Abstract

: This paper proposes motion-trajectory generation for mechanical systems that can be widely used in industrial applications. Many industrial systems, such as feed drive tables, gantry cranes, and material handling systems, are operated using S-curve acceleration and deceleration trajectory, and simple controllers that allow only such a simple motion trajectory are employed from the viewpoints of controller hardware and implementation cost efficiency. This study deals with simple mechanical dynamics including vibration properties and derives a necessary and sufficient condition for the motion trajectory to suppress residual vibration. Simulation and experimental results demonstrate the validity of the proposed conditions.

A Novel Method to Reduce the Laser Drilling Time for Hole Cluster considering the Influence of Residual Vibration of the Sample Stage

“…e common solution to this problem is to set the laser irradiation delay so that the laser pulses are irradiated after the attenuation of the residual vibration [16]. When the motion actuator is a robot arm, the residual vibration tends to be larger and the decay time is longer, which seriously affects the entire drilling efficiency [17,18].…”
