Modeling and Analysis of Monolithic Tri-Axial Ring Laser Gyro

In air crafts, missiles and ships, during their motion, the sensors are prone to undergo lot of vibrations and shocks. Because of their sensitivity to these environments they malfunction. In order to avoid this situation all the sensors are modelled and analysed at the ground for different parameters viz. temperature, vibration and shock etc. A Ring Laser Gyro (RLG) is used for sensing the angle of rotation of missile. Hence application of the gyro in missile is very important and required to qualify against the stringent military specifications. This paper mainly covers the modelling and analysis of tri-axial ring laser gyro which consists of three gyros in a single block, called as monolithic block, with square resonator. The model will be analysed for its resonating frequency and correction of model is done respectively. The modelling of triaxial gyros is carried out using UNIGRAPHICS and is analysed using ANSYS software package. KeywordsRing laser gyro Modeling, Model Analysis, Frequency
