- W2887524141 abstract "The double damper system played an important role in shock absorption and noise reduction of the heavy hydraulic rock drill. However, its floating characteristic had negative effects on rock drills' percussion performance. Based on the operation principle, damping piston's statics equations were established by law of orifice flow. The key indicator parameters of damper system's floating characteristic were ascertained, which were damper flow rate and feed force. Their effects on the percussion performance were researched by experiment. The results indicated that the rock drill had the best percussion performance under a certain impact position, which was uncertain because of the damper system's floating characteristic. There was a greatly effect on the percussion performance of the damper flow rate and feed force. The greatest impact power discrepancy was 5.98 kW with different combinations of them. The negative influence would be amplified with impact power's rising, which should be given attention." @default.
