摘要：

The present paper deals with dynamic stress analysis of the L-1 low pressure steam turbine blade. The mathematical and finite element modeling employed to capture the effect of stresses on the dynamic response of the turbine blade assembly. From the mathematical modeling, the various governing differential equations of motion for lateral vibration of cantilever beam have been derived. The finite element model of AISI420 L-1 low pressure stage steam turbine blade used in the present work is developed by using three dimensional scanning technique. (c) 2018 Elsevier Ltd.
