(中國核電工程有限公司,北京 100840)[摘要]目前,沒有一種計算方法可以妥善解決殼體結(jié)構(gòu)的穩(wěn)定計算問題。對冷卻塔穩(wěn)定性分析常用的幾種方法及其理論進行了介紹,并以某超大型冷卻塔為例,采用ANSYS軟件,對其穩(wěn)定性進行驗算與分析,得到該超大型冷卻塔穩(wěn)定性分布規(guī)律,提出冷卻塔殼體厚度取值的建議。[關(guān)鍵詞]超大型冷卻塔; 穩(wěn)定性; ANSYS中圖分類號:TU33+2 文獻標(biāo)識碼:A 文章編號:1002-848X(2014)21-0082-04Analysis on stability of super-large cooling towersLiu Yan, Liu Min, Yang Jianhua(China Nuclear Power Engineering Co., Ltd., Beijing 100840, China)Abstract: Recently, there is no calculation method to solve the problem of the stability of shell structures properly. Some common methods and theories of stability analysis for cooling towers were introduced. Taking a super-large cooling tower as an example, the stability was calculated and analyzed using ANSYS software. The distribution of the stability of the super-large cooling tower was got, and some suggestions for the thickness of shell of cooling towers were given.Keywords:super-large cooling tower; stability; ANSYS作者簡介:劉焰,學(xué)士,高級工程師,Email:bysj-ly@163.com。參考文獻[1]GB/T 50102—2003 工業(yè)循環(huán)水冷卻設(shè)計規(guī)范[S].北京:中國計劃出版社,2003.[2]張軍鋒,葛耀君.現(xiàn)行規(guī)范中雙曲殼體冷卻塔靜風(fēng)局部穩(wěn)定公式來源[J].建筑結(jié)構(gòu),2011,41(3):100-109.[3]張軍鋒,葛耀君,趙林.基于風(fēng)洞試驗的雙曲冷卻塔靜風(fēng)整體穩(wěn)定研究[J].工程力學(xué),2012,29(5):68-77.[4]王新敏.ANSYS工程結(jié)構(gòu)數(shù)值分析[M].北京:人民交通出版社,2007.
