Development of measurement precision of sensor vibration.

In this paper, an accelerometer mathematical model is developed and simulated to choose the best damping rate value to limit the measurement error to 1%. Using this model, the equations of relative movement modulus and measurement error with respect to damping rate and frequency ratio can be determined. The developed model is validated by a series of tests carried out by computer simulation. The obtained results have shown that a suitable damping rate can minimize the measurement error of relative movement to 1 %. The presented model is a useful tool to improve the damping rate and measurement precision of the accelerometer. [ABSTRACT FROM PUBLISHER]
