3 Overview

Accelerometers (including with built-in amplifier, the charge - voltage converter, etc.) usually Conditioning instrument (such as a charge discharge Amplifier) equipped with, for vibration and shock acceleration measurement. It is mainly the group consisting of mass, the piezoelectric element and the base and other sensitive Into which the piezoelectric element can be a sensitive quartz crystal or piezoelectric ceramics. Accelerometers use piezoelectric effect piezoelectric sensitive element of work, namely. when the accelerometer is fixed to the measured vibration When the object, the piezoelectric element by the force of inertia mass, resulting in a charge proportional to applied force, and the charge Acceleration is proportional to the mass. When the measured vibration frequency is much lower than the natural frequency of the vibration system of accelerometers, acceleration The amount of charge generated in the same meter sensor accelerometer absolute acceleration is proportional to the base, so the accelerometer output Instantaneous value and the amount it feel mechanical vibration acceleration is proportional to the instantaneous value. Reference accelerometer test method must be absolute, as the comparison test work accelerometer transfer standard.

4 metering performance requirements

4.1 Uncertainty sensitivity magnitude and phase shift measurement Frequency range of 0.4Hz ~ 10kHz, acceleration amplitude in the range of (0.1 ~ 1000) m/s2 accelerometer Sensitivity magnitude and phase shift measurement uncertainty of the requirements in Table 1.
