BİR RELÜKTANS FIRLATICININ SONLU ELEMANLAR YÖNTEMİ İLE İNCELENMESİ

Bu çalışmada, Sonlu Elemanlar Analizi ile çözüm yapabilen Ansys Maxwell yazılımı kullanılarak bir sargılı relüktans fırlatıcının modeli oluşturulmuş ve oluşturulan modeldeki parametreler değiştirilerek çıkış hızı en yüksek olan sistem belirlenmiştir. 3 farklı malzemeden imal edilmiş (AISI1020, AISI1050 ve AISI12L14), 2-6 mm çapında, 2-10 cm uzunluğundaki mermilerin fırlatılması analiz edilmiştir. Analiz sonucunda merminin yapıldığı malzemenin geçirgenliğinin, merminin uzunluğunun ve merminin çapının, merminin namlu çıkış hızı üzerindeki etkileri belirlenmiştir. Gerçekleştirilen modelde fırlatma gerilimi DC 250 volttur.
