Description

technical field

[0001] The invention relates to the technical field of fatigue and durability experiments, in particular to a structural fatigue / durability experiment system and method in a complex environment. Background technique

[0002] Major equipment or major engineering structures in the fields of land transportation, shipbuilding and ocean engineering, water conservancy and hydropower, ports, wind power generation, aviation, civil engineering, engineering machinery, etc., often work under the coupling of various service environments and loads. The service environment is diverse and time-varying, and the external loads it bears are often variable-amplitude loads that vary with time and space or even random loads. For the anti-fatigue / durability design and safety evaluation of these major equipment and major engineering structures, most of the experimental data currently based are from constant-amplitude fatigue experiments of materials (specimen) or small components, ...
