With the degradation of electrical connector performance, the intermittent failure (IF) may occur in connector when subject to vibration, thermal and humidity stress. Intermittent failure is generally a precursor to a permanent fault (PF). During the whole life cycle of the electrical connector. The dynamic parameters such as frequency and duration of intermittent failure, evolve continuously with...
Contact stress of vane seals is studied by using numerical and FEA method based on the linear elasticity theory. Results show that numerical model is appropriate to predict the distributing curve of contact stress when the maximum normal strain is lower than 10-15%. But, with sealed extrusion, finite element analysis (FEA) would be better due to the complexity of the material properties, local geometry...
In order to solve a series questions at present existing in machining technology of the disc with complex shape such as long process flow, great affects among working procedures and high cost, according to the outline of the part, the drawing process has been finished by one process instead of two, which is on the basic of the finite element numerical simulation and the experiment on simple dies....
A Tokamak is an important research device in controlled nuclear fusion. A toroidal field coil (TFC) system is an important part of a Tokamak, it produces a toroidal field (TF) to confine the plasma, so it is crucial to analyze the force-structure of the TFC in Tokamak design. In order to research the design method of TFC, we analyze the structural force and deformation of the TFC. The results are...
