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。

In this paper some novel adaptor circuits are proposed to realize the unit element wave switched eapacitor filters driven by two phase clock signals. These circuits are very insensitive to the bottom plate parasitic capacitanees. To realize an adaptor only one unit-gah buffer is needed. The effects of top plate parasitie capacitanees and switch parasitic capacitanees on the adaptor are analyzed. The results show that the effects of the parasitics are small and can be reduced further by changing only one of the capaeitances. These cireuits are adaptable for realizing programmable filters and very useful to the PLC real-time speech synthesis. As an example, a 5th order unit element low-pass filter is given. The experimental results are in good agreement with the theoretical ones.

本文给出了实现单位元波开关电容滤波器适配器的几个新电路。这些新适配器电路仪用一个单位增益器和一个两相时钟信号,而且电路特性对主寄生电容效应极不敏感。文中还分析了次寄生电容(包括电容器上极板对衬底的寄生电容和开关的寄生电容)对电路特性的影响。分析表明,整个次寄生电容效应表现为对反射系数的影响。通过调整一个电容,就可以把这种本来就很小的影响降至更小。另外,本文的电路还非常适合用于实现程控滤波器,可以有效地进行实时语声综合。最后,给出了一个五阶切比雪夫低通滤波器的例子。实验结果与理论相符。
