Dynamic Analysis of a New Type of Hydro-viscous Drive Winch

摘要

A new type of hydro-viscous drive (HVD) winch was designed by combining with differential gear train and HVD. It could meet the requirements of inclined hoist. In order to achieve good control properties, though dynamic modeling and simulation, the output moment curves of HVD device were obtained, then, the working processes of starting, braking and lowering weight were analyzed. Research results provide a theoretical basis for making control strategies for HVD winch. Finally, the starting process of HVD winch was studied in the experimental device; the result indicated that the starting curve of HVD winch efficiently in accordance with Harrison curve.
