- The control of beam halo - chaos becomes a critical problem in the development of high intensity accelerator . efforts to remove the halo by collimation have been largely unsuccessful since the halos almost always regenerate . the mechanisms of halos are complex , such as nonlinear resonances and chaotic behavior etc . considering this , professor fang jin - qing who works in china institute of atomic energy pointed out that the theory of chaos control can be used to control beam halos . he presented the method to control halos by using nonlinear functions , which means nonlinear function g is added to the right of ion radial self - edlctric force equation and some nonlinear function are selected to control beam halos in simulations . in paper [ 69 ] , controllerg = - 0 . 15sin ( rmax - am ) 2 was used and the halo intensity was decreased to 0 . 1078 , the halos are removed partly
束暈?混沌的控制是新一代強(qiáng)流加速器研制的關(guān)鍵問題，隨著強(qiáng)流離子束應(yīng)用前景的日趨廣闊而日益成為研究的熱點(diǎn)。傳統(tǒng)機(jī)械限束器因無法解決束暈的再生而收效甚微，因?yàn)槭鴷灥男纬捎兄鋬?nèi)在動(dòng)力學(xué)機(jī)制?非線性共振以及混沌等?；诖耍袊?guó)原子能科學(xué)院研究員方錦清將混沌控制的理論和方法開創(chuàng)性的運(yùn)用于束暈?混沌的控制上，提出了控制束暈?混沌的非線性控制策略，即在粒子徑向所受束自生場(chǎng)力方程的右邊加上非線性控制函數(shù)g ：并選取一些非線性函數(shù)如等進(jìn)行了控制的模擬研究，將束暈強(qiáng)度控制在0 . 1078左右，取得了初步的控制效果。 - In this paper , we give a summary of controlling chaos and a review of the mechanism of beam halo and its nonlinear control . then delayed self - controlling feedback method is presented to control beam halo - chaos . this method , not only can control beam halo - chaos well , but also is easy to work out because of the linearity and the simpleness of its controller . considering the advantage in technology realizing and cost saving , this method is recommended to the development of high intensity accelerator
本文在綜述混沌控制和回顧束暈?混沌形成機(jī)制及其非線性控制的基礎(chǔ)上，提出了應(yīng)用延遲反饋控制束暈?混沌的方法。該法不僅控制效果顯著，而且由于采用線性控制律，控制器形式簡(jiǎn)單，施加的反饋較小，因此該法非常有利于工程技術(shù)實(shí)現(xiàn)和降低控制代價(jià)，可為實(shí)用強(qiáng)流加速器的研制提供有價(jià)值的參考。 - It can be seen from the results that the control beam had good plastic property in the static failure experiment after two million fatigue loading circles . all specimens with corroded main bars were failure under the fatigue loads within one million fatigue circles . fatigue lifespan of reinforced concrete beam was sharply shortened after main bars corroded in it and the beam was destroyed bristly without any prediction
試驗(yàn)結(jié)果表明,振動(dòng)測(cè)試不能夠?qū)︿P蝕鋼筋混凝土梁的疲勞破壞做出可靠的預(yù)測(cè);對(duì)比梁在經(jīng)過200萬次疲勞循環(huán)加載后的靜力試驗(yàn)中仍表現(xiàn)出良好的延性破壞特征;銹蝕梁在100萬次疲勞循環(huán)內(nèi)均因主筋疲勞斷裂而破壞;主筋銹蝕使得梁的疲勞壽命急劇縮短;梁發(fā)生脆性破壞而沒有征兆。
