This paper describes an analytical study undertaken on an electromagnetic actuator design with a displacement amplification mechanism by explaining the physical modeling and formulizing the actuation time of the actuator in terms of physical model variables. This is followed by an experimental investigation on the actuation time of the electromagnetic actuator. Increasing the gap between the electromagnet and armatures to increase the stroke of the electromagnetic actuator resulted in a drastic loss of the thrust force. The displacement amplification mechanisms were used to increase the stroke of the actuator without incurring high levels of loss in the thrust force. For the same load and final stroke of the actuator, the actuation time was observed to model the effect of amplification ratio on the actuator. Using the physical and mathematical modeling of the displacement amplified electromagnetic actuator and by formulating the actuation time, simulations were implemented that revealed the relationship between the actuation time and amplification ratio. The design of the experimental setup and methodology of the experimentation are explained to verify the simulation results and calculated relationship between the amplification ratio and actuation time in practice. The results of simulations and experimentations showed that there is an optimum point until which the amplification ratio can be increased while advancing from actuation time for the same load and final stroke of the actuator. The similarity between the simulation and experimental results proved that the value of this optimum point could be formulized and expressed in terms of other variables used to simulate the actuator.

Analytical solutions to orthotropic variable thickness disk problems Eraslan, Ahmet Nedim; Varlı, Ekin (2016-01-01) An analytical model is developed to estimate the mechanical response of nonisothermal, orthotropic, variable thickness disks under a variety of boundary conditions. Combining basic mechanical equations of disk geometry with the equations of orthotropic material, the elastic equation of the disk is obtained. This equation is transformed into a standard hypergeometric differential equation by means of a suitable transformation. An analytical solution is then obtained in terms of hypergeometric functions. The ...
Calculation of parameters of single-phase PM motor for design optimization Ertan, Hulusi Bülent; Capolino, GA (2005-09-01) This paper presents methods of calculation of parameters of single-phase permanent-magnet (SPPM) motor, in terms of motor dimensions and material properties, which are utilized in the dynamic model of the motor. The intention of the study is to develop means of SPPM performance calculations, which lend themselves to be employed within a mathematical design optimization approach. The calculated parameters are compared with measured values and are shown to be accurate for the purpose of the study.
Experimental Realization of Single Current Diffusion Tensor Magnetic Resonance Electrical Impedance Tomography Sadighi, Mehdi; Şişman, Mert; Açıkgöz, Berk Can; Eyüboğlu, Behçet Murat (2020-08-08) To obtain low-frequency anisotropic conductivity distribution of biological tissues recently Diffusion Tensor Magnetic Resonance Electrical Impedance Tomography (DT-MREIT), which is combination of DTI and MREIT techniques, is proposed. There are two in vivo applications of DT-MREIT in the literature where two linearly independent current injection patterns are used. Decreasing the number of current injection patterns to one improves the feasibility of DT-MREIT in clinical applications. In this study, DT-MRE...
Experimental evaluation of cable drum systems as linear motion sensors KILIÇ, ERGİN; Dölen, Melik; Koku, Ahmet Buğra (2011-04-15) 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.
Radiation impedance study of a capacitive micromachined ultrasonic transducer by finite element analysis Bayram, Barış (2015-08-01) In this study, radiation impedance of a capacitive micromachined ultrasonic transducer composed of square-shaped membranes arranged in m x m configuration (m = 1 - 5) is investigated using finite element analysis (FEA) of a commercially available software package (ANSYS). Radiation impedance is calculated for immersed membranes operating in conventional and collapse modes. Individual membrane response within the multi-membrane configuration is analyzed, and excited modes and their effects on radiation imped...
