Farklı Barikat Tiplerinin Patlama Basıncına Karşı Koruma Kapasitesi

Öz

1. Özet Endüstriyel kazalar veya terör saldırıları gibi çeşitli nedenlerle meydana gelen patlamaların oluşturduğu basınç dalgaları, koruma amaçlı kullanılan barikatlarla etkileşime girerek karmaşık basınç dağılımlarına ve bölgesel yük artışlarına yol açabilir. Bu durum, barikatların beklenen koruma rolünü tam olarak yerine getirememesine ve belirli bölgelerde risklerin artmasına neden olabilir. Bu kritik sorunu ele almak için, mevcut çalışmada çeşitli geometrik tasarımlara sahip yaygın barikat tiplerinin patlama basıncına karşı performansı ayrıntılı bir şekilde incelenmiştir. Bu araştırmada, deneysel doğrulama ile de desteklenen AUTODYN yazılımı kullanılarak sayısal bir analiz yöntemi kullanılmıştır. Yapılan analizler, barikatın geometrik formunun basınç dalgalarının yansıma, sönümleme ve iletim özelliklerini belirlemede kritik bir rol oynadığını ve dolayısıyla koruma seviyesini doğrudan etkilediğini açıkça ortaya koymuştur. Elde edilen veriler, patlama yüklerine maruz kalabilecek alanlarda can ve mal güvenliğini artıracak daha etkili ve optimize edilmiş barikat tasarımlarının geliştirilmesi için somut bir temel oluşturmaktadır.

Protection Capability of Different Types of Barricades Against Blast Pressure

Öz

Pressure waves created by explosions caused by various reasons such as industrial accidents or terrorist attacks interact with the barricades used for protective purposes and can lead to complex pressure distributions and regional load increases. This situation can cause the barricades not to fully fulfill their expected protective role and increase risks in certain regions. To address this critical issue, the present study conducted a detailed investigation of the performance of common barricade types with various geometric designs against blast pressure. This investigation employed a numerical analysis method using AUTODYN software, corroborated by experimental verification. The analyses performed clearly revealed that the geometric form of the barricade plays a critical role in determining the reflection, damping and transmission characteristics of the pressure waves and thus directly affects the level of protection. The obtained data provide a concrete basis for the development of more effective and optimized barricade designs that will increase the safety of life and property in areas that may be exposed to explosion loads.
