Simulation and Experimental Study on Dynamic Characteristics of Rapid Hydraulic Hoist
摘要
Abstract
The Pinglu Canal project adopts a multi-tiered water-saving ship lock,which offers advan-tages in water conservation and adaptability to high water heads.However,the filling and emptying opera-tions are substantially more frequent than those of conventional ship locks.To ensure lockage efficiency,the valve opening and closing speeds must be significantly increased—specifically,the opening speed should be no less than 8 m/min and the closing speed no less than 16 m/min,which are two to four times the conventional rates.This study focuses on the actual fast-acting requirements of the hydraulic hoist in the canal project.A kinematic mathematical model of the hoist is established,and the load characteristics of the working valve are analyzed.A simulation model of the hydraulic system is developed,and three rapid closing oil-filling schemes—accumulator oil filling,high-level tank oil filling,and pump-direct oil fill-ing—are comprehensively compared and evaluated.Prototype tests are conducted to validate the simulation results.The results indicate that,considering dynamic refueling performance,technological maturity,structural stability,and reliability,the high-level tank scheme is the most reasonable.The prototype test results are generally consistent with the simulation predictions,with a maximum relative error of approxi-mately 4.1%.The measured maximum opening speed is about 8.2 m/min,and the maximum closing speed is about 16.1 m/min.The designed fast hydraulic hoist exhibits good dynamic control performance.关键词
