Abstract: Q345R steel is the most commonly used material in fabrication of the pressure vessels and boilers in China, due to its excellent properties. In 2010, ASME code case 2642 accepted Q345R steel for use in construction of ...

Abstract: The wear of multiple joints with clearance is one of the main impacts on the life of mechanical systems while very limited study has been done on this subject. To be different with many existed researches focused on the ...

Abstract: The finiteelement approach of absolute nodal coordinate formulation (ANCF) is a possible way to simulate the deployment dynamics of a largescale mesh reflector of satellite antenna. However, the large number of finite ...

Abstract: Mesh reflectors with large apertures have been used in many communication satellites. The performance of antenna reflectors crucially depends on the faceting error of the reflective surface, which is approximated by using ...

Abstract: The brittle fracture prevention model is of great importance to the safety of pressure vessels. Compared to the semi-empirical approach adopted in various pressure vessel standards, a model based on Master Curve technique ...

Abstract: The recent advancements in structural health monitoring technology are truly remarkable [1,2], with the utilization of sophisticated methods, such as finite element analysis [3], mathematical statistics [4], and artificial ...

Abstract: The fuel optimization of the spacecraft is significant for its service life. In this paper, a fuel optimization method is proposed to solve the fuel optimization problem of the pursuer in the spacecraft pursuit-evasion ...

Abstract: The krill herd (KH) algorithm is widely used for optimizing truss structures as no gradient information is necessary, and only a few parameters require adjustment. However, when the truss structure becomes discrete and ...
