The usual concern related to construction vibration is build-ing damage. A considerable amount of research has been done to define acceptable levels of construction-induced vibration to limit damage to neighboring buildings. Pre- and post-construction inspections and real-time monitoring
The vibration gradually decreases and returns to zero sometime after the 4 second time window. For a multiple hole blast, the vibration arriving at a remote point is more complex. Each hole is fired at a different time and from a different location, which may introduce a directional variation to the vibration (see Section 7.4). 27409591.doc 7
Oil contamination resulting from externally ingested particles is one of the major causes of journal bearing failure in industrial machinery. The present study has been carried out to assess the case of externally ingested particle contaminants in a journal bearing lubrication using acoustic emission (AE) and vibration monitoring techniques.
