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?
To test the frequency of a vibration, you will need a vibration sensor, such as an accelerometer, and a data acquisition system, such as a computer or oscilloscope, to record and analyze the data.
The vibration sensor should be securely mounted to the object or surface that is vibrating. The data acquisition system should be connected to the sensor and set to record the data. It is also important to ensure that the equipment is calibrated correctly for accurate measurements.
The data acquisition system will record the vibration data over a certain time period. This data can then be analyzed using software or by hand to determine the frequency of the vibration. The frequency can be calculated by finding the number of peaks or cycles in the data and dividing by the time period.
While some smartphones have built-in sensors such as accelerometers, they may not be accurate enough for precise frequency measurements. It is best to use specialized equipment designed for vibration testing.
Yes, it is important to wear appropriate personal protective equipment, such as gloves and safety glasses, when handling equipment and working near vibrating objects. It is also important to follow all safety guidelines and procedures provided by the equipment manufacturer.
