[Abstract]:The research on the dynamic characteristics of accelerometers provides an important support for the applications of accelerometers in aviation, weapons and other fields. Accelerometers have inherent dynamic characteristics. With the improvement of the precision of the accelerometer, the requirement of the test system integration is raised.
