Abstract: This paper describes how optimal shapes for axisymmetric pressure vessels can be established based on maximizing limit pressure. This type of problem has been rarely examined in the literature ...

Abstract: The body of knowledge on design for maintainability (DfM) is increasing. However, there is currently no systematic analysis of the diversified DfM-related issues and research. Through a systematic review of selected papers ...

Abstract: To effectively evaluate the contact characteristics of a particle system, an aggregate contact-slip tester was developed in this investigation on the microscopic level. Contact indexes, including the maximum slip force, ...

Abstract: Asphalt binder is very sensitive to temperature and exhibits bonding or lubrication effects at different temperatures. The bonding/lubrication properties of asphalt affect the mixing, compaction, and service performance ...

Abstract: Electric vehicles use lithium-ion batteries as their power source; however, many researchers have expressed concern about the safety of these batteries. In this study, a new method was used to establish an accurate model ...

Abstract: Lithium-ion batteries are currently the most suitable power source for new energy vehicles. Thermal runaway is the biggest potential safety hazard. To achieve safer battery and battery design, it is necessary to fully ...

Abstract: In recent years, the use of drones has becomes more common in commercial applications as well as among hobbyists. However, the characteristic loud buzz emanating from their use has been an issue, causing a nuisance to the ...

Abstract: Aiming at raising the efficiency of multidisciplinary optimization of UAV rotor aerodynamics and aeroacoustics, this paper established a low-order method of rotor aerodynamics and noise prediction based on lifting line ...
