چکیده

The Department of Mechanical Engineering is one of four departments within the Thomas J. Watson School of Engineering and Applied Science at the State University of New York (SUNY) at Binghamton. The undergraduate educational experience emphasizes the application of a wide spectrum of engineering fundamentals. Care has been taken to ensure a balanced integration of theory, design and laboratory practice through the selection and sequencing of courses within the curriculum. All undergraduates take a senior level course on Mechanical Vibrations which covers a wide range of analysis methods for multi-degree of freedom systems along with techniques for vibration control. A four semester course sequence in vibration is offered at the graduate level covering the analysis of continuous systems, noise and vibration control, random vibrations and nonlinear vibrations. The senior year mechanical engineering lab includes three experiments that provide “hands on” experience with the concepts covered in the Mechanical Vibrations course.

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...

Nonlinear and Non-stationary Vibration Analysis for Mechanical Fault Detection by Using EMD-FFT Method

The Hilbert-Huang transform (HHT) is a powerful method for nonlinear and non-stationary vibrations analysis. This approach consists of two basic parts of empirical mode decomposition (EMD) and Hilbert spectral analysis (HSA). To achieve the reliable results, Bedrosian and Nuttall theorems should be satisfied. Otherwise, the phase and amplitude functions are mixed together and consequently, the ...

A distance e-learning platform for signal analysis and measurement using FFT

The fast Fourier transform (FFT) and the power spectrum are still powerful tools for analyzing and measuring both stationary and transient signals in power systems. However, the misapplications of FFT can lead to incorrect results caused by some problems such as aliasing effect, spectral leakage, and picket-fence effect. Measurement errors can be efficiently reduced by understanding fundamental...

Design and Implementation of a Kalman Filter-Based Time-Varying Harmonics Analyzer

Nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. Many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. Common techniques applied for harmonics measurement and assessment such as FFT have significant errors in presen...
