三峡工程连续五级船闸上闸首人字门液压直联式启闭机 1∶ 2 0物理模型试验研究表明 ,建立的伺服式液压启闭机及其计算机控制系统 ,在模型试验中可实现各种变速运行方式 ;启闭机采用无级变速运行时 ,能较大幅度地降低动水阻力矩峰值 ;动水阻力矩峰值与闸门角的加 (减 )速度基本呈线性关系 .
The Three Gorges Project continuous five-level ship lock gate Shimenzi straight-line hoist 1: 2 0 physical model test research shows that the established servo hydraulic hoist and its computer control system in the model test can be achieved When the hoist adopts continuously variable speed operation, it can greatly reduce the peak value of hydrodynamic torque. The peak value of hydrodynamic torque and gate speed increase linearly.
