起重机运行状态下转速转矩测量方法综述

A Survey of Measurement Method of Rotating Speed and Torque of Crane in Operation

摘要: 起重机作为重型装备核心组成，其运行状态下的转速与转矩参数直接决定设备安全性能与作业效率。本文系统梳理近15年国内外起重机转速转矩测量技术，我们定义“直接测量”与“间接估算”两类方法的判别标准：前者指通过传感器直接获取扭转轴或其附加元件的物理形变信号，后者则基于系统外部可测参数通过建模反推。在此基础上，对比不同方法在测量精度、动态响应、成本控制等维度的差异，总结从“静态单点测量”到“动态实时监测”、从“单一参数建模”到“多场耦合分析”的研究演进路线。

Abstract: Crane is the core component of heavy equipment, and its speed and torque parameters directly determine the safety performance and operation efficiency of the equipment. This paper systematically reviews the domestic and foreign crane speed and torque measurement technology in the past 15 years, and defines the criteria of “direct measurement” and “indirect estimation”: the former refers to the physical deformation signal of the torsion shaft or its additional components directly obtained by the sensor, while the latter is based on the external measurable parameters of the system through modeling. On this basis, the differences of different methods in measurement accuracy, dynamic response, cost control and other dimensions are compared, and the research evolution routes from “static single-point measurement” to “dynamic real-time monitoring”, from “single parameter modeling” to “multi-field coupling analysis” are summarized.
