Accelerometer
Nov 20, 2018

Accelerometer A meter that measures acceleration. Acceleration measurement is an important topic raised by engineering technology. When an object has a large acceleration, the object and the instruments it carries and other objects without relative acceleration are subjected to a force that produces the same large acceleration, that is, a dynamic load. To know the dynamic load, the acceleration is measured. Secondly, to know the spatial position of each instantaneous aircraft, rocket and ship, the acceleration can be continuously measured by inertial navigation (see the gyro platform inertial navigation system), and then the integral component is used to obtain the velocity component, and the integral is again obtained to obtain the position in one direction. The coordinate signal, and the instrumental measurements in the three coordinate directions synthesize the motion curve and give the spatial position of each moment the aircraft is located. As in some control systems, the acceleration signal is often required as part of the information required to generate the control, and the problem of continuously measuring the acceleration also occurs here. A device that can continuously give an acceleration signal is called an acceleration sensor.
