To solve the problem of clutch engagement smoothness caused by uncertain factors such as non-stationary random cyclic load
a method for estimating the uncertainty of the clutch engagement process control is proposed. Taking the clutch engagement process of heavy load reverse operation of a 5 t loader under V-type working condition as the research object
the uncertainty expression of the speed difference between the driving and driven ends of the clutch engagement is obtained by reducing the order of the torsional vibration equation of the clutch engagement process and on the basis of constructing the parameter expression of non-stationary random cyclic load uncertainty and the time-varying model of clutch engagement friction torque. Transmission parameter calibration
bench test and numerical simulation are conducted
and the results show that the method can reali-e the analysis of clutch engagement smoothness and the uncertainty threshold estimation. The uncertainty estimation metho
