| Abstract: |
| During the process of lowering the paper roll onto the guide rail in a wide-web high-speed paper winding machine， the hydraulic cylinder of the primary arm was prone to uncontrolled movement and increased inertial impact， which could lead to collisions between the paper roll and the guide rail as well as hydraulic shock.In this study， a hydraulic system model established via AMESim software was adopted for simulation analysis， which identified that the substantial increase in load mass （from approximately 5 000 kg to 50 000 kg） is the root cause leading to rail collision of the paper roll and hydraulic shock generation. It was revealed that the core problem lies in the insufficient dynamic response of the conventional hydraulic control system under high-load operating conditions. Accordingly， an optimized scheme was proposed by adding a buffer branch combined with stepwise pressure relief control. Simulation results demonstrated that the proposed optimization strategy could significantly reduce the instantaneous collision velocity between the paper roll and the guide rail from -14.0 mm/s to -6.7 mm/s， with a reduction rate of 52%. Furthermore， field applications on actual equipment had verified the effectiveness of the optimized scheme. The modified system basically eliminated impact phenomena， and the quality of paper rolls met industrial production requirements. |
