A new magnetic launcher design and analysis: An ANSYS Maxwell application

Öz

In this study, a new magnetic launcher design consisting of ring and cylindrical permanent magnets without using any mechanical propellants is proposed. In the design, first two ring magnets were used, then one ring magnet was added each time, and the launcher length was changed. In launcher designs of different lengths, the distance between the ring magnets has been increased at a constant value and the cross section of the magnet bullet to be launched has been kept variable. The variations of the magnetic force applied to the magnet bullet according to the position were determined after the analysis for each launcher design of different sizes created by using the ANSYS Maxwell simulation program. Thus, the effects of changing the bullet cross-section and increasing the launcher length by constant steps on the magnetic force were found. In addition, in the case of using coils instead of ring magnets, which play an active role in the magnetic force acting on the bullet, it has also been tried to determine the variables related to the coil. Thus, it has been ensured that the driving force can be changed according to the variable current to be given to the coil. In the article, the creation of launcher designs with the ANSYS Maxwell program and the results obtained are discussed in detail.

Yeni bir manyetik fırlatıcı tasarımı ve analizi: Bir ANSYS Maxwell uygulaması

Öz

Bu çalışmada herhangi bir mekanik itici kullanmadan halka ve silindirik şeklindeki sabit mıknatıslardan oluşturulmuş yeni bir manyetik fırlatıcı tasarımı önerilmiştir. Tasarımda önce iki halka mıknatıs kullanılmış daha sonra her seferinde bir halka mıknatıs ilave edilerek fırlatıcı boyu değiştirilmiştir. Farklı boylardaki fırlatıcı tasarımlarında halka mıknatıslar arası mesafe sabit değerde arttırılmış ve fırlatılacak mıknatıs merminin kesiti de değişken tutulmuştur. ANSYS Maxwell simülasyon program kullanılarak oluşturulan boyları farklı her bir fırlatıcı tasarımı için mıknatıs mermiye uygulanan manyetik kuvvetin konuma göre değişimleri analiz sonrasında belirlenmiştir. Böylece mermi kesiti değişiminin ve fırlatıcı boyunun sabit kademelerle arttırılmasının manyetik kuvvete olan etkileri bulunmuştur. Ayrıca mermiye etkiyen manyetik kuvvette etkin rol oynayan halka mıknatıslar yerine bobin kullanılması durumunda bobin ile ilgili değişkenlerin belirlenmesine de çalışılmıştır. Böylece bobine verilecek değişken akıma göre itici kuvvetin de değiştirilebilir olması sağlanabilmiştir. Makalede fırlatıcı tasarımlarının ANSYS Maxwell programıyla oluşturulması ve elde edilen sonuçlar ayrıntılı olarak tartışılmıştır.
