Experimental research was carried out to investigate the characteristics of tip vortex cavitation (TVC) caused by in an oscillating hydrofoil. Shanghai Shipping and Research Institute's looped tunnel served as site experiments. The hydrofoil used test NACA (National Advisory Committee for Aeronautics) 63820. Two high-speed cameras, one torque sensor, six hydrophones were employed capture patterns, exerted on hydrofoil, noise, respectively. flow under static angle attack (AoA) dynamic AoA...
This article constructs two adaptive control laws to achieve deformation reduction and attitude tracking for a rotary variable-length crane arm with system parameter uncertainties asymmetric input-output constraints. Two auxiliary systems are given deal the input constraints, an asymmetric-logarithm-barrier Lyapunov function is established achieving output constrains, five constructed handle uncertainties. Besides, design based on partial differential equation model, S-curve acceleration...
Rub-impact is a common nonlinear fault of the rotor system, occurring in rotating machines with radial clearance between and stator, which may lead to serious consequences. Since vibration response rub-impact shown as multicomponent time-varying characteristics undulatory instantaneous frequency, it desired exploit advanced signal processing methods for rub-related feature excavation failure diagnosis under complex noise interferences, crucial significance ensure stable efficient operation...
Francis turbine is a core energy conversion part and low frequency vibrations caused by unsteady vortex rope in the draft tube may damage unit through resonance. Therefore, more comprehensive assessment monitoring of status great significance for stability. In this hydraulic machinery, mechanical impulses excitation are co-existing. The former manifests as narrow band with high kurtosis, while latter represents wide associated rope. Based on that, novel method coined Convkurgram proposed to...
Internal waves are one of the most pronounced oceanic phenomenons to oceanographer. During past decades much effort has been made investigate effect internal on shallow water acoustic propagation. Even though many field observations, such as SWARM '95, have provided fruitful information about relation between and propagation, it is necessary conduct more numerical simulations due their extensive feasibility. In this study, wave environment constructed by using a non‐hydrostatic ocean model,...
Efficient and energy-saving are the development tendencies of pre-bending machine. The new machine is consisted a constant pump driven by servo motor instead common motor, variable proportion valve. advantage this hydraulic system it’s closed-loop which controls system. In order to get different flow, it needs adjust speed control unit. This not only has good performance, but also can significantly reduce energy consumption.
Aiming at solving the problems of unbalanced cloud data center virtual host network link bandwidth utilization and multi QoS (Quality Service) security issues in different services, this paper, a based traffic scheduling model for machines is proposed.In order to achieve global optimal scheduling, uses Shannon information entropy measure balance linear weighted sum method transform objective optimization into single problem.At same time, we put forward algorithm on particle swarm...
Resource allocation is the process of optimizing rare resources. In area security, how to allocate limited resources protect a massive number targets especially challenging. This paper addresses this resource issue by constructing game theoretic model. A defender and an attacker are players interaction formulated as trade-off between protecting consuming The action cost which necessary role resource, considered in proposed Additionally, bounded rational behavior model (Quantal Response, QR),...
