  • According to the geometrical characteristic of the arch dam shape, and based on the parameter design language of ansys software ( apdl ), the subp method and the stochastic search method are adopted together to optimize design of hyperbolic arch dam with variable thicknesses of the circle
    摘要根據(jù)拱壩體形的幾何特征,基于ansys軟件的參數(shù)化設(shè)計(jì)語(yǔ)言(apdl),將零階近似方法和隨機(jī)搜索法結(jié)合起來(lái)對(duì)單圓心變厚度雙曲拱壩進(jìn)行了優(yōu)化設(shè)計(jì)。
  • A new waveguide made of changing a wide wall of a rectangular waveguide to a uniform curved wall is called conformal waveguide . a kind of expression of approximate solution for domain mode of the new waveguide, including symmetric, unsymmetric arc, parabolic arch, hyperbolic arch, elliptic arch, etc ., is constructed by using boundary condition of mental waveguide, variational method and boundary element method . by using the equivalence principle, an approximate calculating formula for equivalent resonant conductance of a narrow longitudinal halfwavelength slot cut in the curved wall of the unsymmetric arcrectangular waveguide is derived, and the result is shown . although this solution is approximate, it can solve the problem in designing the slotted antenna of such conformal waveguide
    把矩形波導(dǎo)一個(gè)寬面外突成均勻曲面構(gòu)成的新波導(dǎo)統(tǒng)稱為共形波導(dǎo).利用金屬波導(dǎo)邊界條件、變分法、邊界元素法構(gòu)造這種新波導(dǎo)中主模場(chǎng)的一種近似解表達(dá)式,包括曲面橫截線為對(duì)稱、非對(duì)稱圓弧,拋物線弧,雙曲線弧,橢圓弧等.然后根據(jù)等效原理,推導(dǎo)非對(duì)稱圓弧矩形波導(dǎo)曲面上窄的縱向半波長(zhǎng)縫隙的等效諧振電導(dǎo)的近似計(jì)算公式,給出計(jì)算曲線.這種解雖然是近似的,但卻能解決這類共形波導(dǎo)縫隙天線的工程設(shè)計(jì)
