Abstract: The vibration isolation and absorption technologies for ship mechanical systems were reviewed, such as the concept, the application background, and the research status of floating raft vibration isolation systems and dynamic vibration absorbers. Meanwhile, the concept and development of passive cont...
Abstract: Based on the symplectic superposition method (SSM) pioneered by the authors, the buckling problem of typical non-Lévy-type orthotropic cylindrical shells was solved analytically, which is difficult to handle with conventional analytical methods. The Hamiltonian system-based governing equations for b...
Abstract: To analyze the overall overturning and sliding stability of girder bridges with bearing failures, the stiffness matrix of the 7-DOF curved beam element was derived, and the constraint equations for the bearing detachment and slippage failures were presented. The finite element equation with the cons...
Abstract: Under complex loads, the distributed dislocation technique (DDT) was used to discuss the bifurcating crack problem in a semi-infinite plane, and its correctness was verified. Based on the criterion for the equivalent stress intensity factor, the cause for crack bifurcation was preliminarily explaine...
Abstract: To study the mutual law between the vertical shaft wall fracture and the internal strain, a physical model for the shaft wall was built to simulate the process and state of the shaft wall stress fracture. The distributed optical fiber technology was used to monitor the internal strain of the shaft w...
Abstract: The coupling effects of mobile manipulators on the motion characteristics of mobile platforms during the dynamic operation process, would increase the complexity and nonlinearity of the whole system and then bring great challenges to the system modelling. A new hierarchical aggregation modelling met...
Abstract: Seawater desalination is one of the most promising solutions to fresh water shortage all over the world. The rapid development of nanotechnology led to the boom of nanoporous membranes for water purification. Recent theoretical and experimental studies reported ultra-high water permeability and salt...
Abstract: The infiltration-runoff processes of slopes during rainfall were of significance in the mechanism study of rainfall-induced landslides, debris flows, and other geological disasters. To realize the numerical simulation of the whole rainfall infiltration-runoff process and further improve the computat...
Abstract: The coupled level set and volume of fluid (CLSVOF) method was used to simulate the collision process of glass bead droplets with the same diameter, with the physical mechanism during the collision-separation behavior of glass bead droplets mainly studied. Based on the comparative verification with n...
Abstract: The wellbore hole simulator as a high-temperature high-pressure thick-walled container, is an experimental device used to simulate the high-temperature high-pressure downhole environment of oilfield. Based on thermodynamics and the large eddy simulation (LES) theory, a physical equation was establis...
