Abstract: Abstract. The computation of bolts in pipe flange connections has received significant attention in engineering practice. However, few studies have systematically been done to compute member stiffness in the design of tie ...

Abstract: Large, complex, expensive, and longlived equipment often operate in harsh environments, which leads to the requirements of lifecycle maintenance, repair, and overhaul (MRO). To support the continuous improvement of ...

Abstract: Strengthening titanium alloys and mitigating their wear degradation at various temperatures is the key to industrial applications. In this study, high-performance Ti6Al4V alloy (here, Ti with 6.25 wt% Al and 4.17 wt% V) ...

Abstract: Efficiency and accuracy play an important role in numerical simulation for ball bearings dynamics. In this work, three kinds of contact models are developed in vector form to represent the interactions in ball/raceway, ...

Abstract: Wear is one of the major causes that affect the performance and reliability of tribo-systems. To mitigate its adverse effects, it is necessary to monitor the wear progress so that preventive maintenance can be timely ...

Abstract: Modeling and characterizing high-dimensional aerodynamic pressures, on the elevator in the hoistway, is very challenging. An accurate model is helpful to understand and analyze the pressure characteristics, which is a vital ...

Abstract: Abstract. The variable stator vane (VSV) is a specialized component in aerospace engines, and unclear wear mechanisms in its internal shaft–bushing system could potentially jeopardize flight safety. To explore the tribological ...
