Abstract
A new basic structure based on a bidirectional thermally expanded flow gyro is proposed and its sensitive mechanism is revealed. The temperature field inside the sensitive element of the bi-directional thermally expanded flow gyro is calculated by using the finite element method and a three-dimensional model with COMSOL. The calculation results show that the bi-directional thermal expansion flow gyro has gyroscopic effect, the input angular velocity is in [−40rad/s, 40rad/s], the structural sensitivity of the gyro is 0.9293K/rad/s. The gyro has the advantages of high shock resistance, high sensitivity, cross-coupling suppression and simple process, and can be used in electronic equipment, aerospace and medical instrumentation.
