| Abstract: | Thrust forces, generated by thermal distortion of steam and oil pipings joined to steam turbines, during operation, and acting on the turbine proper, constitute important potential factors for inciting vibration of a set. The paper suggests a comprehensive test study method for exploring the influence of piping thrust forces on the operational safety steam turbines, which has been used in various on site failure diagnosis.
