“…A FSW study [2] is to investigate the process of friction stir welding (FSW) by using finite element method (FEM). Acoustic Emission (AE) method proposed in another paper as a novel approach was used to evaluate residual stress in friction stir welding (FSW) of 5086 aluminum plates using a FEM by [3]. In another paper, an attempt has been made to develop a thermo-mechanical finite element model to analyze the formation of drilled hole and bushing on the workpiece by [4].…”

Sıcak şekillendirme işlemlerinde sürtünme delme işlemleri sıklıkla kullanılmaktadır. Bu işlem delme işlemlerine benzer ancak talaşsızdır ve ince cidarlı metal bileşenlerin birleştirilmesi için kullanılır. Oluşturulan sürtünme ısısı malzemeyi plastikleştirir ve zımba türündeki takımın malzeme yüzeyine girmesini sağlar, böylece sürtünmeyle ek ısı oluşturur. Besleme aleti basıncı ile bir delik oluştururken malzeme yüzeyine ilerlemektedir. Sürtünme delme işlemi parametrelerinin tork ve eksenel güç, sürtünme delme işlemi için ısı transfer katsayısı olarak hesaplanması amacıyla analitik bir model ve yazılım geliştirilmiştir.

“…Due to the highly concentrated instantaneous heat input, residual stress is inevitably generated during and after welding. Its magnitude and distribution have a vital influence on dimensional accuracy, stress corrosion cracking and safe use of rocket tanks, and can even lead to major safety incidents [5][6][7]. Therefore, a systematical study of the generation and evolution of stress during the welding of AA2219 and accurate obtainment of the distribution state of post-weld residual stress are of great significance to the safety and reliability of welded structures.…”

Scraper conveyor is the main equipment for underground coal transportation, and its high-efficiency and smooth operation is of great significance to safety production. This study simulated the process of transporting bulk coal by the scraper conveyor using the discrete element method. Transporting efficiency of scraper conveyor affected by the chain speed, static frictional coefficient, particle size, and laying angle was studied. Then the relationship between the chain speed, static frictional coefficient and the chute wear was explored. The stress and deformation characteristics of the chute during the transportation were studied by coupling the discrete element method and finite element method. Results showed that the mass flow rate changed significantly with the chain speed and static frictional coefficient, while it varied slightly with the change of particle size and laying angle; the higher chain speed and larger bulk coal led to more serious wear of the chute, and large stress mainly concentrated at the direct contact area and the area under the impact load from the bulk coal. Therefore, when designing the chute structure, it is necessary to ensure the wear resistance and strength of the contact area on the chute. The results could provide a theoretical basis for structural optimization of scraper conveyor.
