How do I conduct structural analysis on steam turbine blades using Ansys apdl?

Click For Summary
SUMMARY

This discussion focuses on conducting structural analysis of low-pressure spindle blades using ANSYS APDL. Key factors include applying forces due to rotational dynamics and steam passage, necessitating knowledge of the blade's distance from the axis of rotation, speed, and steam conditions (velocity, pressure, and temperature). Participants seek guidance on applying constraints and loads to accurately assess stress, strain, and deformation in the blades. Recommendations for resources such as books, journals, and tutorial videos are also requested to enhance understanding.

PREREQUISITES
  • Understanding of ANSYS APDL for structural analysis
  • Knowledge of rotational dynamics and forces
  • Familiarity with steam properties (velocity, pressure, temperature)
  • Basic principles of stress, strain, and deformation analysis
NEXT STEPS
  • Research how to apply loads and constraints in ANSYS APDL
  • Learn about calculating rotational forces on turbine blades
  • Study steam dynamics and its impact on turbine blade performance
  • Find tutorials on structural analysis specific to turbine blades in ANSYS
USEFUL FOR

Engineers and analysts involved in turbine design, mechanical engineers focusing on structural integrity, and students studying fluid dynamics and mechanical systems.

Hello,

i would like to do structural analysis for low pressure spindle blades in Ansys apdl.. but i couldn't do it coz of lack of knowledge about it.. Can anybody explain me where to apply force/ pressure and constraints and how to do it to find stress, strain and deformation in it.. please i had attached picture of those blades..

Any suggestions guys??
 
One of the major loads on a turbine blade will be due to the rotational forces acting to hurl the blade away from the spinning rotor. You will need to know the distance of the blade from the axis of rotation and the speed of rotation.

If you want to add a loading on the blade due to the passage of steam, then you must determine the velocity, pressure, and temperature of the steam as it passes thru the particular stage of the turbine where the blade is located.
 
Is there any books, journals or tutorial videos which can i knw.. so that it will be lot easier.. thanks for ur reply
