Evaluation of the power consumption of a high-speed parallel robot

Gang HAN, Fugui XIE, Xin-Jun LIU

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 2, Pages 167-178 doi: 10.1007/s11465-017-0456-8

Abstract:

An inverse dynamic model of a high-speed parallel robot is established based on the virtual work principleWith this dynamic model, a new evaluation method is proposed to measure the power consumption of the robotThese indices can evaluate the power input and output transmissibility of the robot in a workspace.The distributions of the power input and output transmissibility of the high-speed parallel robot areFurtherly, a low-power-consumption workspace is selected for the robot.
