Abstract

Bu çalışmada, UN ECE R58.03 yönetmeliğine uygun treyler arka koruma donanımı içim yeni ve yenilikçi bir tasarım ve bu tasarımın yapısal analizi yapılmıştır. Birleşmiş Milletler (BM) tarafından belirlenen teknik tasarım normları, tasarım parametreleri kilit faktörler olarak kabul edilmiştir. Sonlu Eleman Analizleri (FEA) UN ECE R58.03 yönetmeliğinde belirtilen dayanım test standartları dikkate alınarak yapılmıştır. Donanıma uygulanan analizlerde stres dağılımı değerlendirilmiştir. P1 test durumu analizi stres sonucuna göre menteşe mekanizmasının pimlerinde en yüksek gerilim değeri 839 MPa olarak elde gözlemlenmiş ve P2 koşulunda aynı pimlerdeki gerilim seviyesi 1100 MPa'nın üzerinde hesaplanmıştır. FEA'dan gelen stres verileri dikkate alındığında tasarımın revize edilmesi gerektiği sonucuna varılmıştır. Revizyondan sonra stres seviyeleri azalma gözlemlenmiş, ancak seviyeler kullanılan malzemelerin akma dayanımına yakın olarak saptanmıştır. Elde edilen tüm verilere dayanarak, yazarlar tasarımın üretilecek ve fiziksel olarak test edilecek kadar güvenilir olduğuna karar vermişlerdir, ancak fiziksel testten sonra ek, revizyonlara ihtiyaç duyulabilineceği not edilmiştir.

Design and Structural Analysis of Trailer Sliding Underrun Protection Device Complied with ECE R58.03 Regulation

Abstract

In this study, a new, innovative design and structural analysis of trailer sliding rear underrun protection device (RUPD) that complied with UN ECE R58.03 regulation has been made. The technical design norms that determined by United Nations (UN) were considered the key factor for the design parameters. Finite Element Analyses (FEA) were carried out considering the strength test standards specified in the UN ECE R58.03 regulation. Stress distribution was evaluated in the analyzes applied to RUPD. According to stress result of the P1 test condition analysis, the highest stress value was obtained as 839 MPa on hinge mechanism’s pins and also during the P2 condition the stress level on same pins were above 1100 MPa. Considering the stress datas from FEA, it was concluded that the design had to be revised. After revision the stress levels decreased, but levels were close to the yield strength of materials that used. Based on all data obtained, authors decided that design is trustworthy enough to be produced and physical tested, but after the physical testing additional minor revisions may be needed.
