A shipyard has asked us for measure underwater radiad noise from the hull of a vessel, and they are also asking us to convert the pressure levels obtained to an equivalent noise source strength. Does anyone knows how to calculate the noise source strength of a vessel from the radiated noise...
Hi,
I have done modal analysis of vertical pump. The problem becomes when I compare the results of my model with the results provided by the manufacturer 15 years ago.
Basically in my model the 1st frequency of the shaft is twice the frequency given by the manufacturer. I can get this result...
I would like to model a journal bearing to calculate the whirling frequency of a shaft inside the its case.
I have done some models using a "point radial restrictions", and then I have model the bearings using a two point restriction per bearing (along its length) at the results were quite...
Hi,
I want to measure dynamic stress using strain gauges in a heat exchanger (60ºC), but we can't stop the process to glue the gauges correctly. Has anyone ever glue a gauge in a working machine?, how were the results?.
