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...
Mechanical brake design for passive haptic device
Yilmaz, Serter; Konukseven, Erhan İlhan; Gurocak, Hakan (2011-12-28)
This paper explores a new mechanical brake design to be used in order to limit the motion in low cost and high force passive haptic device design. The designed mechanical brake was inspired from the working principle of a coaster brake used in bicycles. The brake consists of conic surfaces actuated by a DC motor. A leaf spring is added to the system to detect the direction of the user movement. A 1-DOF haptic interface was developed to study virtual wall collisions. Two different prototypes were manufacture...
