Taking a tailings dam in Hebei as the research object, the dynamic response of the dam under action of flood and earthquake is simulated by using a finite element software, and the seismic dynamic response of the dam with respect to acceleration, stress, displacement, liquefaction area and stability are analysed. The results show that, the vertical acceleration increases with the height of the dam,...
A novel structure of VPM machine is presented as an effective option for high torque density direct-driven applications. The novel machine has PMs on both sides of rotor and stator. The PMs on the stator are designed as cylinder and can be rotated by an external driven system. Field can be regulated by the rotation of stator PMs. The structure and operation principle are introduced and the performance...
Glass molding press (GMP) is a kind of mass production method to manufacture infrared aspheric lenses made from chalcogenide. However, it's hard to determine the molding parameters during the GMP process because the lens forming is conducted under the high-temperature conditions. In this paper, the finite element method (FEM) is used to simulate the GMP process based on the general Maxwell viscoelastic...
Proper design of the iron cores is crucial for a saturated iron core superconducting fault current limiter. An optimized design requires guaranteeing sufficient magnetic saturation on the iron cores holding the AC coils, ensuring the efficiency of current limiting, minimizing the use of materials, as well as satisfying the safety and stability obligations. One of the key tasks in the design is the...
