For a project i want to see which viration dampeners would work most effiecently is there any way i could use some sort of invention other then an accelerometer to test this?
You are not too far off. We use microphones to pick up turbine and compressor blade natural frequencies during modal tests. You do sacrifice amplitude information by doing it this way, but really, we are just concerned with finding modes. It is a viable option. You don't have to put anything around the microphone. It does have to be in very close approximation though.Guna82m said:I've a idea..but not sure about it... I think the simplest way is by using sound wave... get a high sensitive mircrophone... embled it in a solid material...I mean cover the microphone with material like clay...then stick the clay on top of the virbrating part...play the recorded sound on a pc... U should be able to see frequency spectrum..
TIPS : there are a lot of freeware to view frequency spectrum of sound data..
Let me know if this works?
