摘要
用边界元法计算受内压小偏心圆筒的最大和最小环向正应力。结果是用无量纲形式表达的,不同内外径比的圆筒在不同偏心率影响下最大和最小环向应力的正曲线,可供计算小偏心液压缸承载能力之用。
This paper uses the BEM to determine the hoop maximun and minimum stresses of the eccentic cylinder. The dimensionless in diagrames which describes the influence of eccentricities can be used for determina.tion of the load carrying of the cylinder.
