Experimental Modeling of a Long Orifice-type Restrictor of High Speed Turbine Hybrid Bearing
To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of ...
متن کاملDirect load measurement of a Wind Turbine High Speed Shaft Bearing in the Field
Small piezoelectric transducers bonded to the outer raceway of a rolling element bearing can be used to send ultrasonic pulses to the element-raceway contact and receive reflections. Interpretation of the magnitude and time of flight (ToF) of the reflections can be used to deduce amount of load imparted between roller and raceway. The approach is most successful when the sensor is smaller than ...
متن کاملHigh Speed Characteristics of VCSELs
The high speed characteristics of Vertical Cavity Surface Emitting Lasers (VCSELs) for use in modern high bandwidth fiber optic networks is presented. An equivalent circuit model based on microwave network analyzer S 11 measurements is developed. The dynamic operation of multi-transverse mode VCSELs is also investigated. Experimentally, a laser with two orthogonally polarized modes is examined....

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولBearing defect size estimation for extended raceway defects
A method is presented for estimating the size of bearing raceway defects that are larger than the angular spacing between balls. Previous defect size estimation techniques cannot be used for such defects since they are limited to defects that are smaller than the ball angular spacing. The reason for this is that two defects that differ in size by the ball angular spacing produce the same time d...
