| 宽幅高速卷纸机在纸辊下放至导轨的过程中，易出现初级臂液压缸运动速度失控、惯性冲击加剧，进而引发纸辊与导轨撞击及液压冲击的问题。本课题利用AMESim软件建立的液压系统模型进行仿真分析，明确了负载质量大幅增加（约从5 000 kg增至50 000 kg）是导致纸辊撞轨并产生液压冲击的根本原因，分析发现关键问题在于传统液压控制系统在高负载工况下的动态响应不足，由此提出了一种增设缓冲支路并结合分级泄压控制的优化方案。仿真结果表明，该优化策略能将纸辊与导轨的碰撞瞬时速度从-14.0 mm/s显著降低至-6.7 mm/s，降幅达52%。此外，现场设备应用验证了此优化方案的有效性，改造后的系统撞击现象基本消除，纸卷质量符合生产要求。 |
| 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. |
