Short communication: Automated testing of accelerometer transversesensitivity with a flexure-based XY compliant stage

Abstract. This paper presents the automated testing of accelerometer transverse sensitivity with a flexure-based compliant stage which can provide vibration on the XY plane. An experimental platform is set up, and the circular tracking error is first obtained to verify the feasibility of the stage. The transverse sensitivity of a three-axis piezoelectric accelerometer is subsequently tested, and it is below 3 %. The difference of the transverse sensitivity under various frequencies is 0.4 %, while the difference of measured direction angle is 2.49, which validates the accuracy of the proposed method.
