Inductively coupled power transfer (ICPT) technology realizes energy transfer across relatively large air gap with magnetic coupling. However, the flexibility of traditional ICPT system is limited because only one-degree freedom is allowed. This paper proposes the design, simulation, and implementation of a novel multi-degree of freedom power pickup mechanism for ICPT system, which can receive power...
This article proposes a new design of a 3D unfolded/tightened mechanism based on the spine structure of golden tree snake, which can realize torsion and bending. Inspired by golden tree snake vertebrae space deformation characteristics, analyzing the anatomy characteristics of the golden tree snake spine bone and muscle distribution characteristics, The bionic mechanism and drive unit can drive the...
In order to research into the fault detection method of bridges, a mathematical model of a simply supported beam with a cracking at mid-span is input with a whitenoise ground motion excitation. The cracking is simulated with gap element, which are able to transfer only longitudinal pressure. Response signals of vertical and longitudinal axial force are analyzed for fault detection purpose, the result...
Brackish water (chlorinity slightly > 250 ppm) in-taking of the Chenhang Reservoir (CHR) from Changjiang Estuary during extremely dry season is an emergency method to ensure the freshwater supply in Shanghai. Mixed with freshwater previously stored inside the reservoir, the chlorinity of output water can below the criterion (250 ppm). In this study, a 3D numerical model was adopted to simulate...
By using shooting method, large deflection bending of the Euler-Bernoulli beam with fixed-free ends subjected to a tip follower force is investigated. Based on geometrically non-linear theory for extensible elastic beams, the governing nonlinear governing equations of elastic beam subjected to a tip-concentrated follower force along the central axis are established. They consist of a boundary value...
Most UAV flight control system simulation was used for evaluating the quality of UAV and designing it, however, the results failed to conform to actual flight laws. According to the need of UAV simulator in actually, a new way which was convenient for engineering computing and appropriated for simulation training was built for simulating flight control system. With the actual flight figures, flight...
