Papers by Keyword: Parallel-Plate Capacitor

Abstract: Parallel-plate capacitor whose plates both fixed to elastic supports is presented and analyzed in this paper, and its cantilevers model is analyzed to study the parameter dependence of pull-in voltage. The whole process of voltage calculation is based on material mechanics theories and analytical methods, and the results are verified by simulation of MEMS software, which is mainly aiming at the effects of plate dimensions on pull-in voltage. It is concluded that the longer are the supporting beams, the smaller are the effects of plate’s parameters on voltage, besides, the effect extent of longitudinal length of plate is little larger than that of transverse length.

Abstract: Process Parameter of slub yarn determine style of its fabric. A new method of measuring process parameter of slub yarn was put forward to improve precision and efficient . The basic principal of parallel-plate capacitor was introduced in this paper. And sample yarns were tested with test system of slubby yarn developed by ourselves. Time sequence for slub length and slub space of slubby yarn can be gotten. And distribution of slub length , slub space and slub scaling factor can also be obtained. The agreement can be attained compared with those original setting. Some error was analyzed also. Consequently this testing system is effectively, and can be adopted in practice.
