what are accelerometer application?

Question

description of accelerometer application

Answer 1

I believe that they are also used in crash test dummies in order to measure impact at the time of the crash.

Answer 2

Accelerometers are used for example in aerospace guidance systems both in launchers and in spacecrafts.
In fact accelerometers measure the acceleration ad
integer of (integer of(acceleration)) is equal to position....of course you need angular measures too using gyroscopes(usually laser-gyroscopes) because these stuffs are moving in 3d space and not on a straight railway.(so at least you need 3 accelerometers and 3 gyroscopes to determine position, nut sometimes there are a 4th of both to be failure-proof)
this kind of complex is usually called inertial platform, and also fighter-attacker military planes are equipped with it, but only as a navigation instrument, not for an autonomous guidance system.
These are only 2 examples ......but they can be used in infinite different ways, also during structural dynamic or vibrational tests.
a large number of accelerometers are also placed in crash test dummies, so looking at accelerations recorded in different parts of the body they determine if that acceleration is too much for an human being.(for example you know that head will brake with an acceleration of XXXX m/s^2, and you compare the values found with this critical value)

Answer 3

Accelerometer is used for measurement of vibrations

Vibrations can be measured by three parameters
01 Amplitude = Distance
02 Velocity = Amplitude/ time
03 Acceleration = Velocity /time

Vibration equation f(x) = m d2y/dx2 + c dy/dx + k
whereas x is the function of time x = a sinwt

Accelerometer is used to measure the acceleration of a vibration waves generated by an external/internal force due to rotation/improper alignment/ applied load.

Answer 4

When I was working as a technician for HP I used an accelerometer to monitor the vibration of high speed pumps.
