摘要:

Finite strip method (FSM) has been considered as a more efficient computational tool than finite element method in solving problems with rectangular geometry and simple boundary conditions. Success of FSM relies on the availability of appropriate eigenfunctions. Difficulty may arise in case of problems having irregular domain and/or complicated boundary conditions. In this paper, by using the orthogonal collocation in the interpolation function, FSM is extended to the solution of problems involving non‐rectangular domain. The proposed interpolation function can be incorporated in the generalized variational functional in dealing with complicated boundary conditions. Application of the method to the bending of elastic plates is demonstrated.

摘要:

This paper presents a numerical analysis of magnetic field distribution in an air gap with the effects of slot depth and width. A dimensionless parametric approach is utilized to cover wide ranges of parameters that frequently appear in electric machine design. A nonlinear two‐dimensional Maxwell equation is solved by using a finite‐difference successive relaxation technique. Constant fluxes are applied for the investigation of nonlinear effect through the region of study, and average reluctances in the air gap are calculated and compared with the Carter number reported in existing literature. Flux plot with normalized air gapG=0.1; besides, various slot depthD,half slot widthW,the Carter number with parametersG=0.1–0.2,D=0.2–3.0, andW=0–0.8 are presented.

摘要:

A two‐phase testing technique is presented for analog circuit fault diagnosis systems. The proposed technique isolates the faulty linear components in the first phase and then using the computed linear component values obtained by phase 1 to determine the input‐output characteristics of nonlinear components during phase 2. The faulty nonlinear components can thus be located. This two‐phase technique takes great advantage of low computational cost since the complex characteristics of the nonlinear components are not directly involved in the calculation.
