【摘要】 对万匹机曲轴分别进行了弯曲、扭转的三维光弹性分析 ,得到了曲轴的弧形凹角和油孔处的最大应力和应力集中系数分布曲线 ,并计算了疲劳安全系数 ,为曲轴的强度计算提供了依据更多还原

【Abstract】 The 3D photoelasticity analysis of the crankshaft of the model of the ten thousand horsepower diesel engine while bended and twisted was described. The distributions curves of the maximum stress and theoretical stress concentration factors in circular shoulder fillet and oil hole of the crankshaft were got. The fatigue safety factor was calculated. These results provide the foundation for calculating crankshaft strength.更多还原
