| Abstract: | Lissajous figures can be used to detect the phase shift of two
signals with a same frequency. This paper introduces a analysis method
for determining dynamic
characteristics of a second order acceleration measurement system with inertial
mass, spring and damping, where the Lissajous figures are used
to detect the dynamic characteristics of the force balance acceleration
sensor, i.e. amplitude response and phase response. The natural
frequency $\omega _{n}$ and damping ratio $\xi $ of the sensor
are determined in order to assess the overall performance of the sensor. |

| Keywords: | Lissajous figure natural frequency $\omega _{n}$ damping ratio $\xi $ amplitude response phase response |
