Fatigue Life Analysis of Blade Operating Oil Pipe of Hydraulic Turbine Based on ANSYS Workbench
As an important part of pressure oil transmission during the opening and closing process of Kaplan turbine blades,the blade operating oil pipe bears the forces of static stress and alternating stress,and may be prone to fatigue cracks which threaten the safe and stable operation of the unit.Based on ANSYS Workbench software,the structural strength and fatigue life of the blade operating oil pipe in Kaplan turbine are numerically simulated under static load and alternating load.The per-formances of the blade operating oil pipe made of two different materials are compared and analyzed under normal operation con-dition.Results show that the two blade operating oil pipes meet the requirements of safe operation under static load,and the 304 stainless steel operating oil pipe has better fatigue resistance than the 20# under alternating load.
