Abstract

The invention discloses an in-situ monitoring system and method for cracks of disc parts in a life assessment test. The in-situ monitoring system for the cracks comprises a sensor device (1), a data acquisition device (2) and a processing device (3), wherein the sensor device (1) is used for detecting the disc parts, the data acquisition device (2) is used for acquiring signals from the sensor device (1), the processing device (3) is connected to the data acquisition device (2), wherein the sensor device (1) comprises a first displacement sensor (4), a second displacement sensor (5) and a key-phase sensor (6), wherein the first displacement sensor (4) is arranged relative to an axis of a life assessment tester so as to detect a first displacement signal of the axis, the second displacementsensor (5) is perpendicular to the first displacement sensor (4) and is arranged relative to the axis of the life assessment tester so as to detect a second displacement signal of the axis, the key-phase sensor (6) is arranged relative to a key-phase groove of an axis of the life assessment tester so as to detect a key-phase signal of the key-phase groove.

Description

technical field [0001] The invention relates to the technical field of crack monitoring of disc parts, in particular to a crack in-situ monitoring system and monitoring method for disc parts used in life assessment tests. Background technique [0002] High-speed rotating parts such as disks of gas turbine engines will generate large centrifugal force under high-speed working conditions. For example, disk parts of aero-engines are key parts of durability and fracture in aero-engines, which directly affect the performance of aero-engines. Reliability, safety and maintenance costs. The damage of disc parts usually cannot be accommodated by the casing of the aero-engine. Once a failure occurs, it will lead to a catastrophic accident and seriously endanger the safe flight of the aircraft. For example, during the flight of a certain type of engine, the wheel disc ruptured, piercing through the casing and engine compartment, causing the power of the aircraft to fail and causing se...
