A new hydrau-electro-mechanical transmission system with soft start-up/stepless speed regulation

Abstract

To meet the requirement of start-up and speed regulation of high-power equipment, a new hydrau-electromechanical transmission system is presented. The system is with the functions of soft start, stepless speed regulation, soft halt, controllable down stroke by own weight, overload protection and explosion proof. The model of the transmission of power is established. Kinematic simulations of various operation conditions have been done with ADMAS software, and the results are encouraging. The physical machinery in reality has gained good economic benefits and social benefits as well.
