Measurement and Analysis of Low Frequency Vibration
نویسنده
چکیده
Low frequency vibration occurs especially in ground transportation, either as a cause in adjacent environment or within the vehicle itself. The piezoelectric accelerometers commonly used for vibration measurement are not suitable, hence other sensors capable of measuring accelerations down to sub-hertz region have to be used. Based on some previous experience with MEMS acceleration sensors a three-axial MEMS accelerometer was interfaced to a data acquisition unit. The digitised data were processed by scripts by Matlab with the aim to discriminate between low frequency translatory acceleration and vibration acceleration. Some preliminary results of this endeavour are presented.

Today there are different vibration isolators used in industries according to the weight and excitation frequency of the machines which have vibration. One of them is Air Spring which is in two types: Convoluted air spring and membrane air spring. Convoluted air springs are used to control vibrations in low frequency (usually lower than 10 Hz) and the membrane ones are used in high frequenc...

Introduction: The available data indicate that there is a relationship between proprioception deficit and low back pain. For this reason, proprioception exercises are usually part of the rehabilitation protocols for these patients. Previous studies revealed that whole body vibration (WBV) can improve muscle performance and proprioception. The aim of this study was to investigate effect of WBV o...

Foam injection is widely applied in amounts of fields to drilling, production, and formation protection. Sometimes, the application result is disappointing, which is caused by the failure of bubble generation in foam flooding. Therefore, it is necessary to seek ways for improving the performance of foam injection. An increased disturbance to the stratum, like the vibration caused by a seismic o...

Transmission of blast waves is a complex phenomenon and the characteristics vary with blast design parameters and geo-technical properties of medium. Frequency of vibration and triggering component for structural excitation generally quantifies safe vibration magnitude. At closer distance or higher elevations than the blast locations, vertical or transverse component will be the first arrival t...

Premature combustion that affects outputs, thermal efficiencies and lifetimes of internal combustion engine is called “knock effect”. However knock signal detection based on acoustic sensor is a challenging task due to existing of noise in the same frequency spectrum. Experimental results revealed that vibration signals, generated from knock, has certain frequencies related to vibration resonan...
