Abstract

Portör tekerleri kundağı motorlu obüsler ve tanklarda kullanılan palet ile araç arasında bulunan özel bir destek tekeridir. Bu çalışmada T-155 Fırtına Obüsünde kullanılan alüminyum alaşımlı malzeme ile flow forming yöntemi kullanılarak üretilen portör tekerinin üzerine etki eden minimum statik yük aracın toplam ağırlığından ve maksimum statik yük ise yapılan sayısal gerilme analizi hesaplamasından bulunmuştur. Bulunan gerilme değerleri kullanılarak özel üretim yöntemiyle imal edilmiş alüminyum portör tekerinin malzeme olarak nasıl bir yorulma karakteristiği göstereceği sayısal ve deneysel olarak test edilmiştir. Portör tekeri üzerinde tespit edilen bölgeden alınan ve ASTM standardına göre üretimi yapılan test numuneleri üzerinde deneysel yorulma testleri yapılmıştır. Yorulma testi yapılmış numunelerin içyapısı incelenerek, herhangi bir yorulma veya çatlak başlangıcı olup, olmadığı gözlemlenmiştir. Böylece flow forming ile alüminyum malzemeden imal edilmiş portör tekerinin gerilme ve yorulma analizleri ile gerçek zamanlı yorulma testi deneyi yapılarak nasıl bir yorulma karakteristiği göstereceği ortaya çıkartılmıştır. Bu çalışmada, katı model geometrisi ve seçilen alüminyum alaşım malzemesinin plastik deformasyon özelliklerine bağlı olarak nihai konfigürasyona ulaştırılan bir modelin maruz kalacağı yük aralığında yorulma dayanımının tayin edilmesi ve flow forming yöntemi ile alüminyum alaşımından yapılmış portör tekerleklerinin aynı yük koşullarında daha hafif ve yorulma direncine sahip aday portör tekerlekleri olduğunu gösterilmesi amaçlanmıştır.

A Study on Endurance of Aluminum Road Wheels Produced by Flow Forming for Tracked Land Platforms

Abstract

Conventional road wheels made by steel material for defense vehicles are generally easy and cheap in production, but it brings extra, undesirable weight to the platforms. It is found that the use of aluminum for road wheels provides weight gain on tracked land platforms. Generally, common manufacturing techniques for road wheels are casting and forging. Since load spectrum that each tracked vehicle road wheel experiences is considerably high and dynamic, casting may not be a good solution for manufacturing due to lower load absorbing capability of casting products. On the other hand, forging might be a suitable method for dynamically loaded road wheels but, it is also expensive as well due to mold and final machining cost. In this study, aluminum alloy material (2014-T6) produced by flow forming method as an alternative to steel is subjected to numerical and experimental stress and fatigue analysis for being used in road wheels of heavy tracked defense platforms. Flow forming method was utilized for effective, cheap and lighter production. Therefore, main focus was put to see the effect of flow forming method on fatigue behavior of aluminum made road wheels. It was concluded that flow forming production method of aluminum road wheel would be suitable method to provide required low cycle fatigue life with advantageous of cheapness and lightness.
