The fatigue reliability analysis for the 16V240ZJB diesel engine crankshaft inserving DF4B internal-combustion locomotive were carried out in thisdissertation.Firstly,according to the fatigue loads of the crankshaft,the bendstress and torsion stress at danger zone in rated operation modes werecalculated respectively.The stress randomicity of the crankshaft was analyzedrelating operation modes of acceptance,and the probability distribution ofstresses were obtained with statistical analysis.

运用本文所提出的疲劳可靠性分析模型(干涉模型-Miner准则综合法及弯扭复合模型)和经分析简化得到的材料p-S-N曲线和p-Sa-Sm-N曲面，分别按一维、二维疲劳应力及弯扭复合应力三种情况对东风4B型内燃机车16V240ZJB柴油机曲轴进行了疲劳可靠性分析。

Overcoming the inability of Forcing Decoupling method, this paper presents a new method-To-Step-Additional-Stiffness method to calculate the translation-torsion coupling seismic response of tile symmetric structures with asymmetrically viscous dampers.

摘要克服强行解耦法不能求解对称结构由于不对称安装粘滞消能器而产生平扭耦合地震作用的不足，提出了一种求解该种情况下的平扭耦合地震反应的新方法－两步附加刚度法。
