It is necessary to perform structure buckling load interval analysis because the uncertainty of structural own parameters should be considered. Critical buckling load of supercavitating projectiles is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each uncertainty variable are deduced  and the interval of structure critical buckling load is calculated by interval analysis and convex model methods. Numerical results show that the nominal value  lower and upper bounds of critical buckling load increase with the increment of the ratio of base diameter to cavitator diameter. And the uncertainty degree of basic variables should be controlled as far as possible in the project for high reliability. 2011 IEEE.   Structure buckling reliability analysis of supercavitating projectile (EI CONFERENCE) 会议论文  OAI收割 2nd Annual Conference on Electrical and Control Engineering, ICECE 2011, September 16, 2011 - September 18, 2011, Yichang, China 作者:  Zhou L. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 Because the underwater velocity of supercavitating projectile is very high  its structure undergo high longitudinal force. It is necessary to perform structure buckling reliability analysis because the randomicity of structural own parameters and flow parameters should be considered. Critical buckling load of supercavitating projectile is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each random variable are deduced  and structural buckling reliability index is calculated by limit step length iteration method. Numerical results show that the critical buckling load and structural buckling reliability index increase with the increase of the ratio of base diameter to cavitator diameter. And structural buckling reliability index increase with the decrease of velocity coefficient. 2011 IEEE.   An evidence of the shadowing effects to the perturbative QCD evolution process 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2000, 卷号: 24, 页码: 991-997 作者:  Ruan, JH;  Zhu, W;  Li, GL   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/16 longitudinal structure function  shadowing correction  QCD evolution equation   An evidence of the shadowing effects to the perturbative QCD evolution process 期刊论文  OAI收割 HIGH ENERGY PHYSICS AND NUCLEAR PHYSICS-CHINESE EDITION, 2000, 卷号: 24, 期号: 11, 页码: 991-997 作者:  Ruan JH(阮建红);  Li GL(厉光烈);  Ruan, JH;  Zhu, W;  Li, GL 收藏  |  浏览/下载：12/0  |  提交时间：2016/06/29 longitudinal structure function  shadowing correction  QCD evolution equation
