    基于面心组合的排气歧管响应曲面优化设计 by 刘伟, 张勇, 程天才, 王海燕

    Published 2021-01-01
    “…In order to solve the limitations caused by the engine exhaust manifold structure optimization which usually adopts single factor control variable method or orthogonal test leading to the insignificant parameter interaction,the face centered combination method in the central composite design is used to respond to surface optimization,taking the engine exhaust manifold of a heavy chemical vehicle as the research object,the exhaust 38 groups of manifold structural parameters finish the fast matching,the mathematical model is established and polynomial response regression equation is concluded,fitting out of the exhaust manifold optimum structural parameters and corresponding flow uniformity index,additionally,the results of response surface optimization is verified by the numerical simulation.The results show that when the four branches are combined,the optimal structure fluid flow uniformity index of the exhaust manifold by the response surface method based on the face centered combination way is improved from the original 0.76 to 0.82,which is 6% higher than the initial structure.…”

    RESEARCH ON STRESS SPECTRUM GROUPING METHOD OF HIGH SPEED EMU BOGIE by CHEN DaoYun, LIU DeKun, SUN ShouGuang, LI Qiang

    Published 2018-01-01
    “…The determination of structural dynamic stress spectrum is of great significance in the structural fatigue strength evaluation as well as reliability design.To evaluate structure of fatigue strength accurately,stress history on fatigue key parts of motor bogie framework was obtained through dynamic stress test of high-speed EMU on actual operation line.Fatigue damage values per kilometer of stress spectra with different grouping numbers were calculated using equidistant grouping method and Palmgren-Miner linear cumulative damage theory.Then,the effect of different group number on fatigue damage was analyzed.The results show that when the grouping number is small,it can lead to deviation of fatigue damage.As the grouping number increasing,damage decreasing,and tends to the theoretical value.This phenomenon can be interpreted by the EMU framework dynamic stress characteristic of small stress cycles high concentration.Meanwhile,an unequal distance grouping method was presented which is applicable to framework structure stress spectrum.The study can provide the basis for framework structure design.…”
