In calculating the strength of V-shaped bottom structure of a planing craft, there occurs a problem of how to calculate the virtual moment of inertia of V-shaped plating.The determination of scantlings of bottom structure largely depends upon the accuracy of the calculated virtual moment of inertia.In the present time, the formulas given by Papkovich, Shimanski and Kurdumov are generally used by naval architects.However, for a given structure, by applying the above three methods, we have obtained quite different...

In calculating the strength of V-shaped bottom structure of a planing craft, there occurs a problem of how to calculate the virtual moment of inertia of V-shaped plating.The determination of scantlings of bottom structure largely depends upon the accuracy of the calculated virtual moment of inertia.In the present time, the formulas given by Papkovich, Shimanski and Kurdumov are generally used by naval architects.However, for a given structure, by applying the above three methods, we have obtained quite different results, and there are also some defects in the assumptions used in each method. A method mostly applied to calculate the strength of materials and the bending theory of beams (including deflections due to shear) have been used by Papkovich to solve the problem of virtual moment of inertia of V-shaped plate.Based on the plane problem of theory of elasticity, Shimanski assumed the plate to he infinite width, and obtained formula for calculating the virtual moment of inertia under two boundary conditions, i.e.the keelson is either simply supported or fixed.By using the theory of beams on an elastic foundation, Kurdumov has taken account of the plane stress condition of the bottom plate and also the case of a keelson having different end fixity only without consideration of the influence of the deformation in bulkheads.An effort has been made by authors in order to make the results more accessible to practical condition.Three V-shaped bottom structure models of different angle of rise, plate width, under different boundary conditions were tested, experimental results are compared with theoretical ones obtained by the authors' method.On the basis of experiments the authors propose a method for calculating the virtual moment of inertia of the V-shaped bottom structure.

在对带斜升的艇底板架板架进行强度验算时,会遇到斜升底板虚惯性矩的计算问题。虚惯性矩计算精确与否,与决定船底各构件的尺度及其分布有很大的关系。目前在设计单位所采用的计算公式多系苏联学者所提出的:如伯潑考维奇法,施孟斯基法以及库尔求莫夫法等。对同一结构在决定其虚惯性矩时,用此三者的计算方法,所得的结果相差很大。且各人的假定还有其不足之处。伯潑考维奇将斜底板以计及剪切变形梁弯曲基本理论为出发点,应用材料力学方法求介虚惯性矩。施孟斯基则以弹性理论平面问题为基础,设底板为无限宽,得到二个极端情现下虚惯性矩计算公式:即龙骨处于自由支持或绝对刚性固定的边界条件。库尔求莫夫别以弹性基础梁的理盐,又计及底板的平面应力与龙骨二端处于不同的边界条件。却未考虑到仓壁变形对虚惯性矩的影响。鉴于上述原因,为了使计算方法能更符合实际情况,对以上的计算方法提出改进的意见。并通过对三种不同斜升角、宽度以及不同的边界条件斜升底板的模型试验,来校验所改进计算方法的精确程度。把试验结果与理论计算比较。在试验基础上提出对斜升废板虚惯性矩计算方法的建议。

This paper consists of three parts. In the first part the 16-dish E-W interferometer of the Mi-Yun Station,Pe- king Observatory(working frequency 146 MHZ)is decribed.Measured instrumental parameters are compared with theoretical ones.Thus the measured beamwidth was 5′.4(5′.3 theoretical),the first sidelobe level amounted to 5%(4.5% theoretical)and the locations of grating lobes in the celestial sphere were very close to the theoretical positions.These show that the surveying of baseline,the installation of antennas and the adjustment of transmission lines are reasonably accurate in our case. The observations of the quiet sun and the slowly varying component are described in the second part.In contrast to the results obtained by some authors(e.g.by O'Ob- rien),we found that the apparent diameter of the meter-wave sun had not varied during the descending phase of the solar cycle. In the third part of this paper the results of measurements of type-Ⅰ sources are analyzed.According to the rate of occurence of type-Ⅰ bursts,the sources are classified into four classes.It is found that(1),the average height above photosphere of so- urces of all classes as measured at the central region of the solar disc was 0.24-R_⊙;(2), the E-W distribution of sources was asymmetric with respect to the solar meridian,in agreement with the result of Fokker;(3),the frequency distributions over the solar disc were different for sources of different classes.The sources containing more type- I bursts decreased more rapidly than the continuum sources with respect to the height;(4),the correlation between the commencement of noise storms with the appearance of optical flares seemed to be rather weak.This differed from the result of Mallinge; and(5),the occurence of noise storm sources was closely connected with the mean flare index of the plage region.As shown in fig.10,for all plage regions asso- ciated with large sunspots and strong magnetic fields,the mean flare index had an average value of 14.33(light solid line,fig.10),among these regions for those also containing meterwave sources,this value rose up to 27.15(heavy solid line,fig.10), while for those which did not possess meter-wave sources,the average index was 7.32 (Chain line).

全文分三部分:第一部分描述了北京天文台密云工作站的东-西16面天线干涉仪系统(工作频率146兆赫),并将仪器参数的实测结果与理论予期值相比较.第一旁瓣5%,瓣宽5.4.方向瓣在天球上的位置也都与理论预期相差不大.第二部分描述了宁静太阳及其缓变成分的观测.在太阳活动下降期没有发现米波太阳视直径的变化.第三部分分析了 I 型源的观测结果.米波源的高度我们测定在过日心径时为光球之上0.24R☉.检查不同类型噪暴源按日心径的分布,得出随着高度的增加 I 型源的噪暴成分比起连续的增强辐射下降得要迅速.在与光学现象的对应上,噪暴的起始似乎与耀斑的发生的相关性不强.噪暴源却与谱斑区的平均耀斑指数有密切关系.
