The Development of Submarine Pipeline Full-scale Fatigue Test Machine

摘要

This paper introduces pipeline full-scale fatigue test machine developed by ourselves,including system constitution, main function, mechanical and hydraulic system design, control system development etc. Host framework design and strength calculation, the main technical parameters of the testing machine, working principle and characteristic is highlighted. The development of the fatigue test machine provide a significant basis for research of pipeline fatigue assessment and design, life prediction, also has the important practical significance and broad application prospects.
