Elements Of Vibration Analysis - Hardcover

Inhaltsangabe

Vibration is the root cause of failure for most rotating equipment in the oil and gas, manufacturing, and other industries. Rotating equipment with relatively long shafts, such as drill strings and vertically suspended pumps, experience detrimental torsional vibrations whenever the torsional natural frequencies are excited. Vibration analysis is a powerful tool in machine fault diagnosis. It is a way to check the status of a machine using a special tool. Troubleshooting machines are often additional known within the future, and before the crash. Fault identification of mechanical or electronic elements or systems could be a subject of knowledgeable system applications. particularly in recent years, vibration measuring has become a very important technique in mechanical structural products analysis, design, produce, apply and maintenance. This book covers comprehensive coverage of the key concepts and innovative techniques in vibration analysis. The book starts with a focus on adaptive torsional tuned vibration absorber for rotary equipment. Rotating equipment with relatively long shafts, such as drill strings and vertically suspended pumps, experience detrimental torsional vibrations whenever the torsional natural frequencies are excited. One of the economical approaches to attenuate vibrations at a selected frequency is through a standard tuned vibration absorbent material. Today, neuro-fuzzy devices area unit emerged by combining network supported adaptational neural networks and fuzzy models. Some of these methods are shock pulse monitoring, crest factor analysis, kurtosis, spectrum analysis, envelope spectrum analysis, wavelet analysis, filtration of signal, etc. This book focuses on intelligent fault detection of retainer clutch mechanism of tractor by ANFIS and vibration analysis. Due to the rise of biological and MEMS technology in recent years, some micro flow system components have drawn attention and been developed by many investigators. Therefore, to investigate the stability and dynamic characteristics of a micro pump is necessary. The Finite element analysis (FEA), ANSYS Workbench, is employed to analyze the dynamic characteristics of this micro pump, and experiment is also considered in this book. Further the book moves to evaluation of shock detection algorithm for road vehicle vibration analysis and a review on detection of cracks present in composite cantilever beam by using vibration analysis technique is presented. Emerging materials and unique methods for their implementation are vital for the success of novel high cycle fatigue (HCF) mitigation methods. The introduction of the shape memory effect, whereby the shape memory alloy material acts as both a damper and a means of variable stiffness is a novel technique for HCF mitigation. Hence, this book in last chapter focuses on active stiffness method for high cycle fatigue mitigation using topical thin foil shape memory alloy. This work serves as an invaluable source for students, engineers, and computer programmers as well as researchers will find this an assistive tool.
