Simulation Analysis of Secondary Lifting and Sliding of Hydraulic Winch During Load Lifting
CHEN Yue
Abstract：Addressing the issue of slippage during the secondary lifting of a heavy load in an open-type pump-controlled volume speed regulation winch hydraulic system,an AMESim software was utilized to construct a simulation model of the winch's mechanical-hydraulic-control system.This model replicated the speed and pressure variation curves during the secondary lifting and slippage of the winch's load.The analysis revealed that the problem stemmed from a mismatch between the activation of the hydraulic brake and the system pressure buildup time.The simulation results indicated that under heavy load conditions,either reducing the opening of the one-way throttle valve at the brake or increasing the initial starting control current of the variable displacement pump could effectively address this issue.
