The hyperelastic shell structures composed of rubber materials have the ability to work in a wide range temperatures, resulting abundant vibration behaviors. Therefore, considering both geometric and material nonlinearities, some different parameter analyzes on nonlinear responses thermo-hyperelastic cylindrical shells containing flowing-fluid (THCSs-FF) are investigated for first time. theory, model, velocity potential energy variational method used establish dynamic model THCSs-FF. To...
This paper presents a passivity-based twisting sliding mode control (PBSMC) approach for series elastic actuators (SEAs). To address the time-varying position trajectory tracking problem in SEAs, fourth-order dynamic model is developed to accurately characterize system. The framework comprises an internal loop and external controller, each designed ensure precise tracking. controller manages second derivative of joint error, while focuses on error itself. Both controllers are based PBSMC...
This paper is concerned with the stability and dynamics of a weak viscoelastic system nonlinear time-varying delay. By imposing appropriate assumptions on memory sub-linear delay operator, we prove global well-posedness which generates gradient system. The possesses finite fractal dimensional exponential attractors unstable manifold structure. Moreover, effect balance between damping are also presented.
The paper investigates a modified adaptive super-twisting sliding mode control (ASTSMC) for robotic manipulators with input saturation. To avoid singular perturbation while increasing the convergence rate, surface (SMS) is developed in this method. Using proposed SMS, an ASTSMC robot manipulators, which not only achieves strong robustness but also ensures finite-time convergence. boundary of lumped uncertainties cannot be easily obtained. A law such that boundaries time-varying disturbance...
Some significant behaviors on strongly nonlinear vibrations are examined for a thin-walled cylindrical shell composed of the classical incompressible Mooney–Rivlin material and subjected to single radial harmonic excitation at inner surface. First, with aid Donnell’s shallow-shell theory, Lagrange’s equations assumption small strains, system differential large deflection vibration is obtained. Second, based condensation method, reduced Duffing equation parameter. Finally, by appropriate...
Water shortage and water environment deterioration are becoming the bottleneck of continuous socioeconomic growth China in 21st Century. Based on development utilisation natural matter cycle rule, authors argued that fundamental approach to resolve crises achieve sustainable resource is establish a healthy cycle. The key strategy this advanced wastewater treatment recycling entire cities. successional researches practices restoration Dalian, Shenzhen, Beijing north-east region were...
This paper is concerned with a multi-domain spectral method, based on an interior penalty discontinuous Galerkin (IPDG) formulation, for the exterior Helmholtz problem truncated via exact circular or spherical Dirichlet-to-Neumann (DtN) boundary condition.An effective iterative approach proposed to localize global DtN condition, which facilitates implementation of methods, and treatment complex geometry scatterers.Under method allows use polynomial basis functions different degree...
In order to scientifically evaluate the water resources carrying capacity of Shandong Province, this paper constructs an evaluation framework nine key indicators, including supply coefficient and per capita GDP, from three dimensions: hydrological resource status, economic social development level ecological environmental protection. Then, entropy weight method combined with TOPSIS model was used carry out in-depth analysis quantitative Shandong's capacity. The results show that: 2015 2020,...
