|Abstract:||Vibration is one of the most classical phenomenon and it has attracted the minds of great newlinescientist right from the days of Sir Isaac Newton. A mechanical vibration in particular has many newlineapplications such as stimulus response analysis, reliability testing, vibration sweep testing, newlineresonance study etc. Vibration testing refers to subjecting a device to some pre-defined profile of newlinemechanical vibrations in terms of amplitude, frequency and time. Various industries like defense, newlinespace, railways, airways, embedded hardware manufacturing etc., during critical phase of testing of newlinetheir products require vibration tests for precise defined profiles. In general, there is a great demand newlineon increasing the reliability of devices making use of critical components. In fact, vibration tests newlinehave become one of the essential and critical tests for all the test and measurement systems newlineincluding the tiny gadgets like personal digital assistants and home appliances. This is newlineaccomplished by intensive vibration tests as this is the main phenomenon responsible for the newlinedurability and serviceability study of various devices. Vibration testing also plays a major role in newlineidentifying faults in the machineries and in the prevention of failures leading to the mechanism of newlinefault diagnostics. Electrodynamic shakers are used as a vibrating platform for carrying out such newlinevibration tests. This research (largely experimental) is organized in two parts. The first section deals newlinewith the design and development of fuzzy logic based intelligent controllers for electrodynamic newlineshaker while the second section deals with the measurement and presentation of complex vibration newlinewaveforms. newline newlineLabVIEW S/W based simulation and measurement tools have been used extensively in this newlineresearch. All the hardware of virtual instrumentation used for signal acquisition and signal newlineconditioning were from M/S National Instruments.|
