Presents the model proposed for analyzing the vibration characteristics of shrouded blades and their calculation method by employing a wave propagation theory and modal synthesis technology coupled with a finite element method from the view point it is possible not only to conduct frequency modulation of the shrouded blades of a gas turbine, but also to utilize the friction effects between them to dissipate energy, thereby attaining the aim of vibration alleviation, as shrouded blades have been widely used in the design of high - speed turbomachinery, such as modern gas turbines and steam turbines, and with the shrouded blades forming an integral whole in a centrifugal force field, the vibration characteristics of the whole ring of blades are different from those of a single isolated blade, and this makes it essential to take into account the integral effect of blade shrouds, concludes from the calculation examples and engineering application that the above approach is valid and correct along with the possibility of considerably reducing the scale of calculation and analysis, and points out it is necessary to take into consideration the coupled effect of the whole ring of blades while the dynamic characteristics of shrouded blades is being analysed
帶冠葉片不但能調頻，還可以利用葉冠之間的摩擦效應來耗散能量，達到減振的目的.帶冠葉片在離心力場中形成一整體，其整圈葉片振動特性不同於單個孤立葉片，需考慮葉冠的整體效應.利用帶冠葉片系統的循環對稱性，提出了採用波傳播理論和模態綜合技術，結合有限元方法研究燃氣輪機帶冠葉片振動特性的分析模型和計算方法.算例和工程應用證明了該方法是效性的、正確的，並可以大大降低計算分析規模.研究表明帶冠葉片動力特性分析時必須考慮整圈葉片的耦合效應In order to make the sensitivity of 2 - demension accelerometer along the two main arbors almost identical, symmetric four - beam structure that embeds a double - sides interdigitated differential capacitive with puckered beam in two directions was used as sensitive component. in addition, the differential capacitive accelerometer fabricated by bulky silicon micromechanical technique has high sensitivity, wide measurement scope, less nonlinear error, and simple converting circuit. then, the structure parameters of the sensitive component were calculated and stimulated, which results in a set of the optimized structure design parameters, main fabrication procedure and several key fabrication technology
