Haptic interfaces require lightweight, small actuators with high force capability and low friction. In this paper, based on the structure of conventional shear mode disc and drum type MR fluid dampers, a lightweight continuous rotary MR damper working in valve mode is designed for haptic interfaces. The proposed design is compared to shear mode disc-type and drum-type designs with similar torque-to mass ratio via computer simulations. Mathematical models for the resistant torques of both the shear mode and the valve mode are derived. Subsequently, the finite element analysis of electromagnetic circuit calculations was carried out by FEMM software to perform an optimization of the dimensions of the parts such as gap size and thickness. It is shown that the proposed continuous rotary valve mode MR damper is a fine candidate that meets the requirements of haptic interfaces.

A VERSATILE MICROCOMPUTER INTERFACE AND PERIPHERAL DEVICES - AN APPLICATION IN DEUTERIUM LAMP BACKGROUND CORRECTION GRAPHITE-FURNACE ATOMIC-ABSORPTION SPECTROMETRY GOKMEN, A; YALCIN, S (1992-01-01) A versatile interface card for Apple IIe computer and various peripheral devices are designed to control instruments which generates transient signals like in graphite furnace atomic spectrometer. The interface card consists of a multiplexed analog-to-digital converter, a digital-to-analog converter, and a timer/counter chip. The timer/counter chip with 16 built-in registers can be programmed in many modes which provides a time base for real-time measurements. A stepper motor runs under the control of ti...
A symmetric surface micromachined gyroscope with decoupled oscillation modes Alper, Said Emre; Akın, Tayfun (2001-06-14) This paper reports a new symmetric gyroscope structure that allows not only matched resonant frequencies for the drive and sense vibration modes for better resolution, but also decoupled drive and sense oscillation modes for preventing unstable operation due to mechanical coupling. The symmetry and decoupling features are achieved at the same time with a new suspension beam design. The gyroscope structure is designed using a standard three-layer polysilicon surface micromachining process (MUMPs) and simulat...
AN AUTOMATIC MODE MATCHING SYSTEM FOR A HIGH Q-FACTOR MEMS GYROSCOPE USING A DECOUPLED PERTURBATION SIGNAL Yesil, F.; Alper, S. E.; Akın, Tayfun (2015-06-25) This paper reports a closed-loop controller system developed for in-run automatic matching of the drive and sense mode resonance frequencies of a MEMS gyroscope with a high quality factor (Q). This is achieved by injecting a perturbation signal to the quadrature cancellation loop, while keeping it decoupled from the angular rate control loop. The new controller is implemented in a CMOS ASIC together with the other sensor control loops, and it is verified to maintain matched-mode state under changing environ...
A new jacobian matrix calculation method to decrease computational time in periodic force response analysis of nonlinear structures Kızılay, Hazım Sef; Ciğeroğlu, Ender; Department of Mechanical Engineering (2019) The contact interfaces between the components used in high speed systems such as the turbo machinery cause nonlinear vibrations. In order to understand the dynamic characteristic of nonlinear systems, it is important to perform nonlinear vibration analysis. In nonlinear vibration analysis, due to the properties of nonlinear elements used, it is not possible to calculate the Jacobian matrix analytically or it becomes very complicated and difficult, therefore, Jacobian matrix is calculated as numerically. In ...
A control system for hydraulic single axis durability test rig Çalışkan, Hakan; Balkan, Raif Tuna; Platin, Bülent Emre; Konukseven, Erhan İlhan (2012-10-19) In this study, a controller is designed for a hydraulic actuator of a single axis durability test rig. The mathematical equations of the system are derived and a MATLAB Simulink (R) model is developed. The non-linear equations defining the system dynamics are linearized and the system is represented in state space. For the position control of the hydraulic actuator, a combined feedforward and feedback controller is designed. The feedforward controller estimates the force transmitted between the vehicle and ...
