1A1-A10 Identification Method of Sensor Directions and Sensitivities in Multi-axis Accelerometer : An Effect of Rotational Transform for the Direction of Actual Sensors(3D Measurement/Sensor Fusion(1))

Abstract

Actual sensors embedded in a multi-axis accelerometer are not aligned with the package directions in general. With former methods, it is difficult to measure the actual sensor directions. This study proposes a new examination method to measure the actual sensor directions and sensitivities. The method uses a new examination system with parallel link exciter mechanism. This report discusses the effect of machining accuracy of the sensor base is described with simulation and experimental results.
