Abstract
For studying the L-HCCF of an actual turbine disk mortise teeth at elevated temperature, this paper presents a new experimental system, using actual disk as experimental component, ingeniously achieving the combined loading (simulating low cycle radial centrifugal force and high cycle crosswise vibration of blade), the high-frequency induction local heating (550 °C constant temperature), the control of high cycle vibrating frequency and amplitude, and the crack real-time detection. The experimental result is identical with the practical flight failure. This method can be easily popularized for the L-HCCF studying of many components.
