TESTING TRANSVERSE SENSITIVITY OF LINEAR SINGLE-AXIS PENDULOUS ACCELEROMETER WITH TRI-AXIAL VIBRATION GENERATOR-A THEORETICAL INVESTIGATION

摘要

To build a specific mathematical model of the relationship between the frequency of the acceleration align with the main sensitivity axis and the transverse sensitivity, testing transverse sensitivity of linear single-axis pendulous accelerometer with tri-axial vibration generator was suggested by many researchers. However, based on the investigation of this paper, the amplitude of the input acceleration is more important than its frequency to the relationship between the acceleration align with the main sensitivity axis and the transverse sensitivity. The conclusion is obtained with respect to a linear single-axis pendulous accelerometer, but useful for analysis of transverse sensitivity of other types of accelerometers.
