| Abstract: | Fluid drive has been widely used in colliery machine presently.However hydraulic impact which has great effects on both service life of hydraulic components and normal working of system is one of common fault of hydraulic system and components in colliery machine.The reason of hydraulic impact is analyzed,and the mathematic model for impact force is set up based on the law of conservation of energy.Control strategies were put forward for the loops and components which produce the hydraulic impact. |
