Abstract: To improve the protective structure design of armored vehicles against intensive blast loadings and ensure the safety of occupants, the dynamic responses of a monolithic beam subjected to impact loading, with occupant safety considered, was studied. First, experiments were carried out to characteriz...
Abstract: Large space membrane antenna has a great prospect in the fields of deep space exploration, space-based early warning and earth observation. Due to the large-size and high-flexibility of the membrane structure, the membrane antenna spacecraft poses challenging dynamic and control issues. Meanwhile, t...
Abstract: The frequent frictional collision between flexible drilling pipe and guide screen as well as drill bit and rock may lead to the failure of flexible drill pipe due to coupling vibration in the side-drilling technology of ultra-short radius horizontal wells, which directly affects drilling safety and ...
Abstract: Aimed at the significant problem of bidirectional random wind vibration responses of large-span asymmetric suspension structures, a strategy was proposed to suppress the vibration of large-span suspension structures with series inerter dampers (SIDs) as the energy damping system (EDS). For the compl...
Abstract: The safety concerns regarding the flammability and explosivity of traditional liquid electrolyte (LE) lithium batteries have spurred the development of all-solid-state lithium batteries with solid-state electrolytes (SSE). However, the issue of lithium dendrite growth remains a critical challenge to...
Abstract: Aimed at the application of heat storage technology in the field of new energy consumption, a molten salt single tank integrating the heat storage and the heat exchange was proposed. The single tank heat storage characteristics and molten salt heat transfer laws during the heat storage process were ...
Abstract: To address the problems of uncoordinated nodal displacements at the intersection of the sparse and dense elements, complicated construction of solving equations, and poor spatial scalability, an element model with variable node numbers and positions was proposed with the base force element method (B...
Abstract: For the numerical modeling of solid materials containing crack-inclusions, the theory of Eshelby's eigenstrain and equivalent inclusion was incorporated into the boundary integral equations (BIEs). A computation model and an iterative algorithm for the eigen crack opening displacement (COD) and eige...
Abstract: The finite time stabilization problem of dynamical directed networks under pinning adaptive event-triggered control was addressed. Unlike the existing results as for finite time stabilization with event-triggered protocol, in view of the difficulties of the control cost and the large node number, a ...
Abstract: The key to whether the WENO scheme can achieve optimal convergence accuracy and maintain essential no-oscillation characteristics near discontinuities lies in the construction of smoothness indicators. The smoothness indicator of the 3rd-order WENO scheme was modified through the construction of a m...
Abstract: A new efficient and compact finite difference scheme was constructed to obtain numerical solutions of the symmetric regularized long wave equation. The classic Crank-Nicolson (C-N) scheme and the extrapolation technique were used for discretization of the 1st-order derivatives in the temporal direct...
