Bu
çalışmada elektromekanik supap mekanizmalarında kullanılabilecek uygun manyetik
devre tipleri incelenmiştir. Disk tipi manyetik devreye elektromekanik supap
mekanizması iki farklı tipte tasarlanmış ve yay sabiti, kütle, besleme gerilimi
ve tutma akımı gibi çeşitli tasarım parametrelerinin sistem üzerindeki etkileri
incelenmiştir. Sistemin statik ve dinamik denklemleri çıkarılarak MATLAB/Simulink
programı ile sayısal çözümleri elde edilmiştir. Prototip iki sistem üzerinde
deneysel çalışmalar yürütülmüş ve teorik sonuçlarla karşılaştırılmıştır. Elde
edilen sonuçlardan benzetim ve deneysel çalışmaların birbiriyle uyumlu olduğu
görülmüştür.

Investigation of the Effects of the Magnetic Circuit Design Parameters on the Electromechanical Valve Actuators

Öz

The
paper describes the suitable type of magnetic circuits used in the
electromechanical valve actuators (EVAs). Two different types of EVA models
with the disc type of magnetic circuits were designed and the effects of
various design parameters such as spring constant, moving mass, supply voltage,
holding force on the system were investigated. The static and dynamic equations
of the system were derived and their numerical solutions were obtained with MATLAB/Simulink
program. The detailed theoretical analysis and experimental tests were carried
out on the manufactured different prototypes of the EVAs. Simulation and
experimental results showed a good agreement with each other.
