To address the failures observed in aluminum-alloy fuel tanks, specifically, cracking of the dual-chamber sealing partition, end cover, and drain boss, finite element analysis was employed for comprehensive calculation and structural optimization. Stress, strain, and displacement under varying load conditions were evaluated, revealing that failures of the sealing partition and end cover were due to stress concentration. At the same time, the cracks in the drain boss were caused by weaknesses in the weld heat-affected zone. Three optimization measures were proposed: adding an R5 chamfer to sealing baffles, incorporating R5 transitional fillets on the reinforcing ribs of the end caps, and designing the drain boss as an asymmetrical elliptical shape with a central transitional fillet. Following these optimizations, the maximum stress on the components was significantly reduced, and the safety factor markedly increased. Results from sealing, pressure, and vibration tests confirmed that these measures effectively enhance the structural strength of aluminum-alloy fuel tanks and extend their service life. This study provides robust support for the design and analysis of aluminumalloy fuel tanks.
This research focuses on the modeling and analysis of metal inert gas welded aluminum alloy and galvanized steel joints using ESI SYSWELD, with an emphasis on evaluating structural stress and thermal behaviour. The materials considered in this study are Aluminum Alloy 6061-T6 and EN10130 DC-04 galvanized steel, widely...

Highlights What are the main findings? Axial compression tests showed that cracks mainly initiated and propagated along the diamond-shaped diagonal-braced surfaces, with the middle column segment being the most vulnerable region. Strain analysis indicated that foam concrete dominated the early-stage axial resistance, w...

Current standards use simplified approaches to predict the resistance of aluminum structural elements, but these often fail to capture strain hardening, instabilities and heat‐affected properties. This paper presents investigations toward an alternative design method for aluminum open cross‐sections, based on the Overa...

The camshaft is a critical component in multi-cylinder engines, responsible for controlling the timing and
operation of intake and exhaust valves.
This study focuses on the design and evaluation of a camshaft using two different materials: forged steel and aluminum
alloy. The objective is to compare their performance i...

The performance and durability of an internal combustion engine are critically dependent on the design and the material selection of its camshaft. Traditional cast iron camshafts, while robust, are heavy and can limit engine efficiency. This study employs finite element analysis to evaluate and compare the structural p...

Tapered steel members offer advantages in structural applications due to their material efficiency and their ability to align with nonuniform internal force distributions. However, their fire performance remains insufficiently studied, and design standards provides limited design guidance. This presented research inves...
