Experimental evaluation of cable drum systems as linear motion sensors

This study evaluates cable-drum mechanisms as linear motion sensors for certain CNC applications. In this work, the dynamical attributes of a generic device are studied experimentally. The conducted research indicates that despite the significant traction force induced between the cable and its drum, small fluctuations in mechanism's speed yields a considerable (micro) slip at the interface.


Experimental evaluation of alternative drive-mode control electronics developed for high-performance MEMS gyroscopes
ŞAHİN, EROL; Alper, S.E.; Akın, Tayfun (2011-06-09)
This paper presents the illustrative measurement results of a comprehensive study for understanding the effects of different drive-mode control electronic architectures on the overall performance of a micromachined capacitive vibratory gyroscope. Three different control electronic architectures have been implemented for generating either (a) square wave, (b) sinusoidal wave or (c) complex waveform driving signals for the gyroscope under test. Performance characterization of the gyroscope with these control ...
Active neuro-adaptive control of a smart beam having uncertainties in structural dynamics
Akın, Onur; Şahin, Melin; Department of Aerospace Engineering (2015)
In this thesis, an active vibration suppression of a smart beam having piezoelectric sensor and actuators is investigated by designing separate controllers comprising a linear quadratic regulator and a neural network. At first, design of a smart beam which consists of a cantilever aluminum beam with surface bonded piezoelectric patches and a designed mechanism having a micro servomotor with a mass attached arm for obtaining variations in the frequency response function are presented. Secondly, the frequency...
Nonlinear 3D Modeling and Vibration Analysis of Horizontal Drum Type Washing Machines
Baykal, Cem; Ciğeroğlu, Ender; Yazıcıoğlu, Yiğit (2020-01-01)
In this study, a nonlinear 3-D mathematical model for horizontal drum type washing machines is developed considering rotating unbalance type excitation. Nonlinear differential equations of motion are converted into a set of nonlinear algebraic equations by using Harmonic Balance Method (HBM). The resulting nonlinear algebraic equations are solved by using Newton’s method with arc-length continuation. Several case studies are performed in order to observe the effects of orientation angles of springs and damp...
Dynamic performances of kinematically and dynamically adjustable planar mechanisms
İyiay, Erdinç; Soylu, Reşit; Department of Mechanical Engineering (2003)
In this thesis, the dynamic performances of kinematically and dynamically adjustable planar mechanisms have been investigated. An adjustable mechanism is here defined to be a mechanism where some of the kinematic and/or dynamic parameters are changed in a controlled manner in order to optimize the dynamic behaviour of the mechanism in spite of variable operating conditions. Here, variable operating conditions refer to variable load(s) on the mechanism and/or variable desired input motion. The dynamic behavi...
Shaft transducerless vector control of the interior permanent magnet motor with speed and position estimation using high frequency signal injection and flux observer methods
Göksu, Ömer; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2008)
In this thesis, shaft transducerless vector control of Interior Permanent Magnet (IPM) motor with speed and position estimation using saliency based high frequency signal injection and fundamental model based flux observer methods will be investigated. The magnetic saliency characteristic of a 2.2-kW IPM motor will be experimentally extracted by means of high frequency signal injection. High frequency signal injection method will be used to estimate the speed and position at zero and low speed based on the ...
