A Dataset from a Hydraulically Actuated Forestry Crane for Data-Driven Stress Estimation (PATU655Stress)

This dataset contains synchronized time-series measurements from a PATU 655 forestry crane operating in a laboratory under planar motion. The crane is actuated using proportional directional control valves. Recorded signals include valve command voltages, hydraulic pressures (cylinder chambers and supply/return), cylinder displacements, boom angles and angular velocities, and five strain-gauge channels on the crane structure. Data were collected using continuous motion, step-type valve excitation, and joystick control. A total of 108 recordings cover multiple payloads (95, 148, 180, 278 kg), hydraulic settings, and crane postures. Data are provided as CSV files (raw) for data-driven stress estimation and modelling.本数据集包含一台在实验室环境下以平面运动模式运行的PATU 655林业起重机的同步时间序列测量数据。该起重机采用比例方向控制阀进行驱动。记录的信号包括阀指令电压、液压缸腔室及供回油路的液压压力、液压缸位移、吊臂角度与角速度，以及起重机结构上的5个应变片通道数据。数据采集采用连续运动、阶跃式阀激励及操纵杆控制三种模式。共计108组记录数据，涵盖了95、148、180、278 kg多种载荷工况、液压参数设置以及起重机姿态。原始数据以CSV文件格式提供，可用于数据驱动的应力估算与建模研究。
