A new attitude control actuator, the vibrating mass gyroscope is considered. The actuator transforms the vibratory motion of a single gimbal gyroscope to a positive or negative, fluctuating control torque. The equations of motion for such an actuator are presented. The feasibility of construction of such an actuator is investigated. Possible means of realizing the vibratory motion is proposed.

Chatter detection using vibrational and acoustic emissions in turning process Süleyman, Büyükkoçak; Kılıç, Şener; Özer, Mehmet Bülent; Ünver, Hakkı Özgür (null; 2013-09-20) Chatter vibration is a longstanding problem for machining industry. It lowers both surface finish quality and life of cutting tool. In this study, real time chatter vibration detection system is designed and tested experimentally. A traditional lathe, equipped with two accelerometers placed on cutting tool in two orthogonal coordinates and a microphone, is used for machining a steel rod in face turning operation. During cutting process analog data of accelerometers and microphone is acquired by data acquisi...
Vibration isolation of inertial measurement unit Çınarel, Dilara; Ciğeroğlu, Ender; Department of Mechanical Engineering (2012) Sensitive devices are affected by extreme vibration excitations during operation so require isolation from high levels of vibration excitations. When these excitation characteristics of the devices are well known, the vibration isolation can be achieved accurately. However, it is possible to have expected profile information of the excitations with respect to frequency. Therefore, it is practical and useful to implement this information in the design process for vibration isolation. In this thesis, passive ...
Optimum geometry for torque ripple minimization of switched reluctance motors Sahin, F; Ertan, Hulusi Bülent; Leblebicioğlu, Mehmet Kemal (2000-03-01) For switched reluctance motors, one of the major problems is torque ripple which causes increased undesirable acoustic noise and possibly speed ripple. This paper describes an approach to determine optimum magnetic circuit parameters to minimize low speed torque ripple for such motors. The prediction of torque ripple is based on a set of normalized permeance and force data obtained from numerical field solution for doubly-salient geometries. For that purpose a neural net is trained to extract the data neede...
Vibration fatigue analysis of structures installed on air platforms Eldoğan, Yusuf; Ciğeroğlu, Ender; Department of Mechanical Engineering (2012) Although a component satisfies all operating static requirements, failures can still occur due to vibration induced fatigue. Vibration induced fatigue is a frequent phenomenon, in cases where the natural frequencies of the structures are excited by the loading. Hence, the methods which consider all dynamic characteristic of the structure should be used to obtain accurate fatigue life predictions. These methods in frequency domain are called vibration fatigue methods which give accurate, reliable and fast re...
