Study on Dynamic Output Characteristics of Liquid - viscous Speed Regulating Clutch and Simulation Analysis of Dil Film Flow Field Between Friction Plates Based on Computer Simulation Technology

Abstract

To improve the drive torque without increasing the installed power of the system, a drive system of “motor + fly wheel + hydroviscous variable speed clutch” is designed. The mathematical model for each energy transmission link of the drive system, the oil film bearing capacity model and the Computer simulation model for the drive system are established to reveal the influence law of the factors such as the fly wheel moment of inertia (MOI) and oil film thickness control curve on the dynamic engagement features of hydroviscous variable speed clutch, obtain the change curve of torque, speed and impact, and build the corresponding experimental bench. The results of the simulation experiment suggest that through reasonable control of the oil film thickness of the hydroviscous variable speed clutch, the output of twice the rated torque that lasts up to 50 s can be achieved to meet the engineering demand of large and medium-sized mechanical equipment for large starting torque and small impact.
