One Motor-Biaxial Rotary Testing Equipment for Measuring Angular Acceleration

Abstract

A simple rotary testing equipment is needed to measure directly angular acceleration. In this paper a simple biaxial rotary equipment is set up by using one motor, a rotating shaft having inclined surface and a table having pivots as a gyroscope, reduding vibratory noise to a certain extent. Secondly, a biaxial angular acceleration sensor is set up using accelerometer of a monolithic IC type. It was cleared that the equipment can be a good excitor for low frequency range.
