Modal Testing and Finite Element Analysis of Crack Effects on Turbine Blades
The study of vibration response of a turbine blade helps to detect the crack presence in the blade which alters its dynamic characteristics. The change is characterized by changes in the modal parameters associated with natural frequencies. In this paper, study of vibration response is made for turbine blade in the presence of a crack like defect. Turbine blade is initially assumed as a cantile...
متن کاملExperimental Modal Analysis of Reinforced Concrete Square Slabs
The aim of this paper is to perform experimental modal analysis (EMA) of reinforced concrete (RC) square slabs. EMA is the process of determining the modal parameters (Natural Frequencies, damping factors, modal vectors) of a structure from a set of frequency response functions FRFs (curve fitting). Although, experimental modal analysis (or modal testing) has grown steadily in popularity since ...
متن کاملPMD Study & Measurement – Fixed Analyzer Method
The paper theoretically describes Polarization Mode Dispersion (PMD) which is important parameter in high-speed optical networks. Furthermore, compensation methods and measurement principles are presented. Main attention is given to Fixed Analyzer (FA) method that uses common research laboratory equipment in setup. We performed practical measurement of the PMD by using Optical Spectrum Analyzer...
متن کاملروشی جدید برای اندازه‌گیری پارامترهای چشمه‌های آلفازای فوق اورانیوم
An alpha-gamma coincidence method, using multi-parameter analyzer (MPA) system in list mode was used for measuring parameters of transuranium sources. The benefit of using the list method is preventing duplication of experiments a lot and thus saving the cost and time taken for this type of testing that due to very small sample rate, spend a lot of time. The multi-parameter analyzer stores the ...
متن کاملARGUS: Supercomputing in 1/10 Cubic Meter
We propose ARGUS, a high density, low power supercomputer built from an IXIA network analyzer chassis and load modules. The prototype is a diskless MPP scalable to 128 processors in a single 9U chassis. The entire system has a footprint of 1/4 meter2 (2.5 ft2), a volume of 0.09 meter3 (3.3 ft3) and maximum power consumption of less than 2200 watts. We compare and contrast the characteristics of...
