Compared to eddy current braking pattern with single magnetic source exciting, hybrid excitation rail eddy current brakes has many advantages, such as controllable, energy saving and various-operating-modes. Aiming at large braking power consumption of high-speed train, a hybrid excitation rail eddy current brake system, which is based on the principle of electromagnetic field, is proposed to fulfill...
In this paper, simulations of railway catenary supporting system have been performed with finite element method (FEM) in different wind and ice-coating disasters with or without a locomotive passing by. The results of stress and displacement indicate that existing catenary supporting structure is capable of meeting the requirement on strength and stiffness in most cases, though, the contact wire will...
Three-dimensional elastic contact model of the automobile gasoline economizer of the one-way gear devices is analyzed on the base of FEM. The work condition is calculated, and the stable stress distribution, strain distribution and the deformation of the outer ratchet, inside core and pawl are obtained. With the FEA analysis results, the intensity reliability of each part is checked based on maximum...
Many stochastic parameters have an effect on the reliability of a steam turbine blade during practical operation. To improve the dynamic strength reliability design of blade, it is necessary to take these stochastic parameters into account. In this paper, a variable-section torsion blade is investigated and a new method which is the combination of finite element method (FEM), response surface method...
This paper presents the design and fabrication of SOI-based MEMS for mechanical memory storage (theoretical analysis and FEM) dedicated to reliability irradiative study. The memory data is the position of a mechanical ldquobi-stablerdquo. The data is written with thermal actuators and read with electrostatic comb electrodes.
