摘要:

爬模式组塔平台是一种稳定且操作简便的组塔技术,其通过液压系统驱动实现平台的往复顶升,为高空作业和物料起吊提供安全支撑。针对液压系统机理复杂、难以建立精确模型及传统方法诊断效率低的问题,本文在AMESim软件中建立了液压系统仿真模型,通过故障注入获得多种典型故障数据。随后,构建基于双向长短期记忆网络(Bi-directional Long Short-Term Memory,BiLSTM)的端到端故障诊断模型,直接以压力、流量和位移等多通道信号为输入,自动提取时序特征并进行分类,实现了无需人工特征设计的智能诊断。实验结果表明,该方法在仿真数据集上的故障识别准确率达到98.5%,验证了其在液压系统故障识别中的有效性与鲁棒性,为组塔设备的安全运行与智能维护提供了新思路和技术支撑。

Abstract:

The technique of climbing-mode tower erection platform is stable and user-friendly. It is driven by a hydraulic system to perform reciprocating lifting of the platform, ensuring safety during elevated work and material hoisting. To address the challenges of complex hydraulic system mechanisms, difficulty in establishing precise models, and low diagnostic efficiency of traditional methods, a hydraulic system simulation model is established in AMESim, and Multiple typical fault datasets are obtained through fault injection. Subsequently, an end-to-end fault diagnosis model based on a bidirectional long short-term memory network(BiLSTM) is constructed. This model directly takes multi-channel signals, such as pressure, flow rate, and displacement, as inputs, automatically extracts temporal features, and performs classification, enabling intelligent diagnosis without manual feature design. Experimental results demonstrate that the proposed method achieves a fault recognition accuracy of 98.5% on the simulation dataset, which validates its effectiveness and robustness in hydraulic system fault identification. This approach provides new insights and technical support for the safe operation and intelligent maintenance of tower erection equipment.
