1results about How to "Avoid direct measurement" patented technology

This invention relates to a turbine disk verification device and method, addressing the problem that existing technologies struggle to simultaneously simulate centrifugal loads, fluid loads, and high-temperature environments on turbine disks, leading to complex and costly verification devices. The invention provides a turbine disk vibration safety verification device and method, comprising a rotating vibration verification unit, a high-temperature vibration verification unit, and a control unit. The rotating vibration verification unit includes a sealed chamber, a drive device, an airflow disturbance device, and a data acquisition module, used to drive the turbine disk to rotate at room temperature and apply periodic airflow excitation to acquire traveling wave vibration parameters. The high-temperature vibration verification unit includes a heating unit, a vibration unit, a temperature sensor, and an acceleration sensor, used to heat the turbine disk and apply high-frequency vibration excitation to acquire vibration response parameters. The control unit coordinates and controls each module and collects data. This invention comprehensively evaluates turbine disk vibration safety by first measuring traveling waves during rotation at room temperature and then measuring fatigue at high temperature without rotation.
