| 中文摘要: |
| 通过分析某钢铁公司一种钢坯在线自动称重液压系统的工作原理，发现该系统负载试车时发生了执行元件油路颤振问题，针对该问题基于AMESim建模仿真，以对该系统进行故障诊断研究。研究发现，该系统存在负负载的垂直升降油路，且直接在液压缸附近安装液控单向阀的做法导致了液压系统下降过程不稳定，从而出现颤振现象。改进后的系统加载试验验证了仿真分析结果的正确性。 |
| 英文摘要: |
| By analyzing the working principle of an automatic billet online weighing hydraulic system in an iron and steel company, it is found that the system has experienced actuator oil route flutter during the load test. To address this issue, a fault diagnosis study of the system is conducted based on AMESim modeling and simulation. The research reveals the existence of a vertical lifting oil route under negative load, and the practice of directly installing a hydraulic check valve near the hydraulic cylinder has caused an unstable descent process in the hydraulic system, thus resulting in flutter. The improved system load test has verified the accuracy of the simulation analysis results. |
