Measurement and Demonstration System Design for Molecular Circular Angular Accelerometer

This paper designs a new kind of molecular circular angular accelerometer based on electric double layer and streaming current to measure angular acceleration directly. A measurement and demonstration system is designed to show the function of this new kind of accelerometer. This system provides angular acceleration input, processes signal from the accelerometer and demonstrates the result on the screen. The experiments come to the conclusion that as for the molecular circular accelerometer, the measurement range reaches 20000(o)/s2, the measuring error is less that 1%, the bandwidth is 120Hz. This new accelerometer can satisfy the requirement of high-accuracy and large range in complex situation. The measurement and demonstration system can provide frequency-controllable and amplitude-controllable acceleration input and demonstrate the function of molecular circular angular accelerometer.
