The Research of Forklift Control System Based on Ultracapacitor

摘要

The forklift is the research object, for the reason of its large application quantities, high fuel consumption and bad emission. It is the important research direction of the energy saving of forklift to improve the working state of engine by means of hybrid technology. Based on the study of energy distribution, the schemes of parallel and series hybrid systems are evaluated, according to their fuel consumption, equipped power of working components and working parameters. The parallel hybrid system with the capacitor as energy accumulator and the project of energy regeneration with hydraulic motors are explored in detail, combining theoretical analysis. Finally, the energy regeneration,with hydraulic motor, is presented and synthetically evaluated.
