This book was released on 1971 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precision autocollimator readout of nearly spherical free-rotor gyroscopes, using a reflecting optical flat, requires that the normal to the flat be aligned with the rotor axis of maximum inertia and that the alignment remains stable during gyro operation. The normal to the flat is defined as the readout axis of the instrument; angular misalignments between the normal and the axis of maximum inertia are called 'flat position errors.' In previous research, initial alignment to within 2 arcseconds has been achieved; however, rotor flat-position errors were found to vary significantly when the gyro spin speed or temperature was changed. This investigation studies the variations as elastic phenomena so that the accuracy and stability of readout-axis orientation in arbitrary free-rotor gyroscopes can be understood. (Author).

Download or read book Stability Of Gyroscopic Systems written by Ardeshir Guran and published by World Scientific. This book was released on 1999-04-01 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motion of mechanical systems undergoing rotation about a fixed axis has been the subject of extensive studies over a few centuries. These systems are generally subject to gyroscopic forces which are associated with coriolis accelerations or mass transport and render complex dynamics.The unifying theme among topics presented in this book is the gyroscopic nature of the system equations of motion. The book represents comprehensive and detailed reviews of the state of art in four diverse application areas: flow-induced oscillations in structures, oscillations in rotating systems or rotor dynamics, dynamics of axially moving material systems, and dynamics of gyroelastic systems. The book also includes a chapter on dynamics of repetitive structures. These systems feature spatial periodicity and are generally subject to considerable gyroscopic forces. “Gyroelastic systems” and “repetitive structures” are the topics with very recent origins and are still in their infancies compared to the other examples represented in this book. Thus, the contributions on gyroelastic systems and repetitive structures are limited to only modeling, localization and linear stability analysis results.This book covers many important aspects of recent developments in various types of gyroscopic systems. Thus, at last, a comprehensive book is made available to serve as a supplement and resource for any graduate level course on elastic gyroscopic systems, as well as for a course covering the stability of mechanical systems. Moreover, the inclusion of an up-to-date bibliography attached to each chapter will make this book an invaluable text for professional reference.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis discusses a technique of precise placement of an optical flat on an almost spherical gyro rotor. An initial flat is placed near the minimum axis of inertia of a sphere. The flat is replaced by successive polishing operations until the minimum axis becomes the maximum axis and a desired alignment of the flat, approximately perpendicular, with the maximum axis is achieved.
