Abstract

Theoretical and experimental results of studies on a stability of slow-speed motion generated by different type rotating platforms designed for an investigation of angular velocity meters are presented. On the basis of simulation, the possibilities to obtain smooth rotary motion have been analyzed. The main attention has been paid to low angular velocity, order of Earth revolution velocity. Slow-speed platforms constructed nowadays exhibit many technical problems caused mainly by wide range of revolution velocity. Very often angular velocity generated by them exhibits large disturbances caused by mechanical principle of action. These disturbances cause oscillations of instantaneous velocity which increase for decreasing mean value of generated angular velocity of rotary motion. In theoretical simulation the role of sub- assemblies workmanship has been discussed. Moreover, the effect of this workmanship on the level of generated rotation velocity oscillations has been estimated. In experimental part, an application of fiber optic gyroscope enabling experimental verification of obtained theoretical results is presented. According this application, the instabilities of angular velocity produced by different rotation platforms have been well visualized and measured.
