A Complete Analysis for Pump Controlled Single Rod Actuators

In the current study a variable speed pump controlled hydrostatic circuit where an underlapped shuttle valve is utilized to compensate the unequal flow rate of a single rod actuator is analyzed. Parameters of the shuttle valve are included in the system analysis, rather than treating it as an ideal switching element as handled in literature. A linearized model of the system is obtained. An inverse kinematic model, which calculates the required pump drive speed for a desired actuator speed and given pilot pressure input, is formed. A numerical stability analysis program is developed, and the stability of all possible shuttle valve spool positons is determined. The theoretical findings are validated by non-linear simulation model responses.

A novel algorithm for prediction off-line stator leakage inductance and on-line stator resistance of induction motors
Sezgin, Volkan; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2009)
In vector control of induction motors it is essential to know the parameters of the motor. Known approaches to this problem have some drawbacks. This thesis work is planned to develop solutions to the existing problems. The proposed solutions will be implemented and tested.
A Mathematical Model for Simulation of Flow Rate and Chamber Pressures in Spool Valves
Afatsun, Ahmet C.; Balkan, Raif Tuna (ASME International, 2019-02-01)
In this paper, a mathematical model to simulate the pressure and flow rate characteristics of a spool valve is derived. To improve the simulation accuracy, the discharge coefficient through the spool valve ports is assumed to be a function of both the Reynolds number and the orifice geometry rather than treating it as a constant. Parameters of the model are determined using the data obtained by computational fluid dynamics (CFD) analyses conducted on two-dimensional axisymmetric domains using ANSYS FLUENT 1...
A Novel Noise Reduction Technology for Switched Reluctance Motors
Bizkevelci, Erdal; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2008-07-24)
The conditions are sought at which an SIR motor can be operated with highest efficiency, while producing a desired torque output at low shaft torque ripple. The investigation is based on the simulation software that uses measured flux-linkage (V, 0, 1) and static torque (T, 0, 1) characteristics of a given motor. The variation of the shaft torque, torque ripple and efficiency of the motor Is investigated, while the control variables "advance angle" and "conduction angle" are swept over their range with a co...

In displacement-based engineering, the maximum interstory drift ratio (MIDR) is one of the most influential parameters for evaluating the seismic performance of existing structural systems. MIDR is also a key parameter in force-based designs satisfying serviceability lit-nits for new structural systems. A set of predictive equations is derived for estimating MIDR on shear-wall systems with fundamental periods ranging from 0.5 to 1.25 s. The equations are derived from a recently compiled ground-motion datase...
A DRBEM solution for MHD pipe flow in a conducting medium
Han Aydın, S.; Tezer, Münevver (Elsevier BV, 2014-3)
Numerical solutions are given for magnetohydrodynamic (MHD) pipe flow under the influence of a transverse magnetic field when the outside medium is also electrically conducting. Convection-diffusion-type MHD equations for inside the pipe are coupled with the Laplace equation defined in the exterior region, and the continuity requirements for the induced magnetic fields are also coupled on the pipe wall. The most general problem of a conducting pipe wall with thickness, which also has magnetic induction gene...
