In this paper, the authors treated the determination of the inertia parameters (virtual mass and virtual moment of inertia) by model tests. The accuracy of the experimental method was first checked by using ellipsoids, the inertia parameters of which were known, the error being about 2%. Then. a body of revolution with a vertical stabilizing fin and rudders at tail has been tested. By conducting such tests, the inertia parameters of the whole body and its components were obtained for different states of...

In this paper, the authors treated the determination of the inertia parameters (virtual mass and virtual moment of inertia) by model tests. The accuracy of the experimental method was first checked by using ellipsoids, the inertia parameters of which were known, the error being about 2%. Then. a body of revolution with a vertical stabilizing fin and rudders at tail has been tested. By conducting such tests, the inertia parameters of the whole body and its components were obtained for different states of motion of the body. The authors also suggested formulas for calculating these inertia parameters. Such formulas have taken into consideration the interferences between the appendage and the main body. Except for the rudder, which needs further investigation, the agree-ment between the calculated values and experimental results is satisfactory. Finally, the effect of the free snrface on the inertia parameters has been considered and denoted by coefficients of decre-ment. Experiments show that the parameters are nearly constant when the depth of immersion of the body is greater than three times the diameter.

在本文中,作者論述了水下运动物体慣性参数(附加质量及附加轉动慣量)的实驗測定。实验方法的精确性,先用慣性参数已知的椭球体检驗之,誤差約在2%左右。然后就回轉体加上垂直鰭及尾舵的組合体进行試驗,测定了此組合体及其各部件在物体各种运动状态时的慣性参数。作者并提出了各部件慣性参数的理論計算公式,考虑了各附件与本体之間的干扰影响。理論值与实验結果之間符合程度,除牵涉到舵外,是令人滿意的。关于舵的部分,还需进一步探讨。本文最后論述了自由表面对慣性参数之影响,并用减額系数表示之。实驗証明,当物体浸水深度超过三倍直徑之后,慣性参数几乎是常值。

Described in this paper is the calculation of hydrodynamic coefficients of submarine horizontal stabilizing fin-rudder assembly by a numerical method of finite elementary solution. Calculation results are basically in agreement with those obtained by experiment. The effects of the aspect ratio, the swept-back, the taper ratio and the area ratio of the rudder itself to the whole assembly on the hydrodynamic coefficients are also studied.

In modern industry,especialy in aviation and astronavigation,curves ofhigh degree give form to the surfaces of many parts,such as those of aircraftwings,missile stabilizing fins and ribbed profiles.Machining these Parts byusing interpolation comparing dot by dot would cause complicated programmingand bring about less accuracy as well.In this paper the mathematical model of direct interpolating curves of highdegree is established on the basis of the pulse interpolation at intervals.Inter-polation is illustrated...

In modern industry,especialy in aviation and astronavigation,curves ofhigh degree give form to the surfaces of many parts,such as those of aircraftwings,missile stabilizing fins and ribbed profiles.Machining these Parts byusing interpolation comparing dot by dot would cause complicated programmingand bring about less accuracy as well.In this paper the mathematical model of direct interpolating curves of highdegree is established on the basis of the pulse interpolation at intervals.Inter-polation is illustrated and its flowcharts are given also presented in the paper isan experimental report on interpolation on numerical-control linear cutting mach-ines controlled by TP801 Z80 microcomputer with a single plate of integratedcircuit.

在现代工业中,特别是在航空、宇航工业中,有很多零件的表面是由高次曲线组成的。如飞机的机翼、导弹的尾翼、肋骨线等。如果在数控机床上用逐点比较插补法加工这类零件,不仅编程烦杂而且插补精度也不高。本文根据脉冲间隔插补法建立了直接插补高次曲线的数学模型、列举出插补实例、拟定出插补流程图。并采用TP801 Z80单板微计算机控制数控线切割机进行了插补实验.
