The need for non-destructive testing/structural health monitoring (SHM) is becoming
increasingly important for gas turbine manufacturers. Incipient cracks have to be detected …

为了解离心叶轮高速旋转叶片的振动特性, 对其进行振动应力测量与叶尖振幅测量,
并将两种方法的测量结果进行对比分析. 在介绍振动应力测量与叶尖振幅测量基本原理及数据 …

Flutter, an aeroelastic blade vibration phenomena, experienced by the fan of an
developmental aero gas turbine engine, result in blade failure. Hence, suitable flutter …

Turbine stages are exposed to a variety of excitation sources in the power industry. The
resulting forced vibration excitation of the blades may occur near a blade's natural …

A recent research program has identified the possibility of using the analysis of casing wall
pressures in the direct measurement of gas turbine rotor blade vibration amplitudes …

This paper presents a summary of a recent research program, focusing on a new method of
non-contact gas turbine blade vibration measurement using casing pressure and vibration …

Currently tip timing methods are the pseudo industry standard for measuring Gas Turbine
blade vibration. The physical placement of tip timing probes is however reasonably …

A recent research program has identified the possibility of using the analysis of casing wall
pressures in the indirect measurement of gas turbine rotor blade vibration amplitudes [1] …

In order to avoid flutter phenomena in blades of a turbine stage, the blades have not been
made equal and they have some differences in their masses and stiffness. These small …

برای جلوگیری از پدیده فلاتر، پره‌ها در یک ردیف از توربین یکسان ساخته نمی‌شوند و در عمل با هم
از نظر جرم و سفتی اندکی تفاوت دارند. این تفاوت‌های اندک را ناموزونی نامند. در این پژوهش به …‎
