The paper begins with a theoretical analysis of potential flow for the two-di- mensional conduit inlet,and after the boundary curve of constant pressure is obtained, it is transformed to the case of axial symmetry.It is hoped that the pressure along the new boundary,be nearly constant.The method of transformation is mainly that for equal distance ratios(i.e.,distance divided by entrance width in the two-dimen- sional case and that divided by entrance diameter in the axially symmetrical case), area ratios(i.e.sectional area divided by entrance area in both cases)are equal. The pressure distribution along the curved wall of an axially symmetric inlet so obtained was calculated by the relaxation method,and that of another was measured from an air-flow model test.The results as given in Figures 10 and 13 of the paper show that although the pressure along the wall is not constant,the variation is not great.The paper finally suggests that as for to reduce the possibility of cavitation, the forms of the axially symmetric inlets given by Equations(5)and(6)of the paper may be considered as adequate for practical cngineering use,with the restriction that the value of k which appears in the two equations not be greater than 0.05,in order to prevent the possible separation of flow from the inlet wall.

文中给出了隧洞进水口曲线为等压的二元分析结果,然后将此二元进水口的曲线形式转变为轴对称进水口的曲面形式。所用的转变方法是:当 x/D=(x_1)/B时,d/D=(b/B)~(1/2),其中 d、x和 D 分别为轴对称进水口段中某断面的直径,由起始断面至该断面的距离和起始断面的直径;b、x 和 B 分别为相应二元情形的某断面的宽度,由起始断面至该断面的距离和起始断面的宽度。对用这种方法得到的一个轴对称进水口曲面上压力分布,进行了松弛法计算,还对另一个进行了气流模型试验。结果如文中图10及图13指明,曲面上压力虽然不是等值的,但变化不大。文中建议,就减蚀的意义而言,式(5)和式(6)所给轴对称进水口曲面的形式是可以考虑来作为实际工程上应用的,但为了避免可能发生水流从边壁上脱离的现象,式中 k 值应取小于或等于0.05。

It is known that in plane finite element calculation the bearing load must be transformed into force of nodal. Currently used methods of transformation are: 1) integral average method, 2) average integral method, and 3) trapezoid method. Since some approximation is made in these methods, the calculation results are approximately nonnumerical.Based on the equivalent theory of statics this paper presents an accurate numerical method and accurate numerical formulas for calculating...

It is known that in plane finite element calculation the bearing load must be transformed into force of nodal. Currently used methods of transformation are: 1) integral average method, 2) average integral method, and 3) trapezoid method. Since some approximation is made in these methods, the calculation results are approximately nonnumerical.Based on the equivalent theory of statics this paper presents an accurate numerical method and accurate numerical formulas for calculating the bearing load distributed by cosine curve law are derived.The method developed in this paper can increase the accuracy of calculated results and be used to draw up a universal computer program for the finite element method.

在平面有限元计算中,必须把轴承负荷转为节点力。现有方法:①积分平均法,②平均积分法,③梯形法。这些方法都作了一些近似假定,所以是近似的非数值解法。 本文根据静力学完全等效原理提出一种精确数值解法,并对余弦分布的轴承负荷转为节点力的解法作了具体的数学推导,得出了精确数值计算公式。 本文提出的解法可以提高平面有限元计算的精确性,便于编制平面有限元计算的通用程序。
