在本文中,作者叙述了所拟制的用于操舵,舵柱力矩测量以及自动控制船模的仪表结构。这种仪表是露天水池中进行试验时用在独立自航船模上的。其制造简单,采用它可以减轻露天水池中船模试验的设备。本文亦说明了试验的方法,并简略地叙述了求得船舶设计时所需各种试验资料的可能性。采用这种简单的仪表于船模试验就有可能求得船舶灵活性和舵机需用功率的资料,并借以合理地选择舵的尺寸,位置和补偿系数。亦有可能研究所设计的船舶的操纵性能,(包括倒航的操纵性能在内)。熟识本文,可能对船舶制造工程师,首先是设计师是有益的,本文着重指出为了要顺利的设计船舶,举行各种船模试验是有很大的实际意义。

In order to make the scope and size of port facilities,e.g., the channels, wharves, waterareas, etc. in portdesign andmanagement satisfactory to the accommodation requirementsof different types and tonnages of ships, it is convenient toclassify all kinds of ships into several design tonnage classes.

In order to make the scope and size of port facilities,e.g., the channels, wharves, waterareas, etc. in portdesign andmanagement satisfactory to the accommodation requirementsof different types and tonnages of ships, it is convenient toclassify all kinds of ships into several design tonnage classes. In this paper, data of nearly 10,000 ships of 3,000~100,000 DWT of both home and foreign fleets were collected. Theywere divided into four categories of general, bulk, oil andcontainer ships and analyzed according to their differenttonnages. Accumulated curves with respect to their differentL. B. T. (length, breadth and loaded draught) were also plotted.The rate of concentration and the draft difference at thelinear inflection point on the curves, together with differencein cost and amount of construction work were taken as themain controlling factors in classifying the tonnage class ofships. It was finally decided that a draft difference of 0.5mwas taken as the interval of grouping the design tonnageclass and their accumulated curves of tonnage were plottedcorrespondingly. In this paper, the classification of tonnage class weredecided by method of analysing and reasoning, with conside-cation of ship characteristics and mainly from an engineeringpoint of view. And a guaranteed rate of 85% by the methodof probability was chosen as the valuation standard ofrepresentative ship dimensions of the design tonnage class.Comparison with what are used in our present ports andwharves and those of foreign countries, shows that theycheck quite closely which means the figures suggested inthis paper may be good for reference.

港口要接纳不同类型和载重吨位的船舶,为了便于港口设计和管理,需将各类船舶划分为一些设计吨级,以使其港口航道、码头和水域等设施的规模和尺度适应设计船舶吨级的需要。本文收集了国内外近万艘3,000~100,000吨的船舶资料,按杂、散、油、集四个船种,作了不同载重吨的资料整理分析,并分别绘制它们的L、B、T(船长、型宽、满载吃水)尺度的保证率曲线。设计船舶吨级的划分是以载重吨保证率曲线疏密程度及其线型拐点处的吃水差作为划分吨级的主要控制因素,结合港口航道、码头工程建设费用和工程量的差别程度,最后确定以吃水差为0.5米作为载重吨合并同一设计船舶吨级控制条件,并相应作出吨级的保证率曲线。本文着重从工程观点出发,考虑船舶特点,以分析和论证方法给出了设计吨级的划分;甲概率方法,确定设计吨级的代表尺度,选用保证率为85%作为取值标准。文中还对我国现有港口码头所选用的船型以及国外一些有关或定型的船舶尺度与本文选用吨级尺度进行比较,基本能概括和接近这些船舶尺度,说明本文所划分的吨级和代表尺度可作为设计船舶吨级尺度的参考。

The main research object of the methodical series presented here is the Yang-Tze River passenger-cargo liner with twin screws. The series is also suitable for the short voyage ships in the Yang-Tze River and other inland water way vessels of similar ship form. The ranges of form parameter of this series are as follows: δ:0.52~0.64 L/B:4.6~7.0 B/T:3.6~6.0 Design charts on ship form and resistance are presented. The resistance charts are shown in the form of residual resis tance coefficient C_R ( F_n=0.2~0.32)....

The main research object of the methodical series presented here is the Yang-Tze River passenger-cargo liner with twin screws. The series is also suitable for the short voyage ships in the Yang-Tze River and other inland water way vessels of similar ship form. The ranges of form parameter of this series are as follows: δ:0.52~0.64 L/B:4.6~7.0 B/T:3.6~6.0 Design charts on ship form and resistance are presented. The resistance charts are shown in the form of residual resis tance coefficient C_R ( F_n=0.2~0.32). This paper also presents the offsets correction and the correction chart of resistance when the waterline coefficient of design ship is different from that of the series. In addition, the correction curves of resitance for varying draught conditions are given. In the resistance charts, the friction resistance is calculated by using I957 ITTC correlation line. A method is given for converting the series resistance into the one when using Prandtl-Schlichting frictional resistance coefficient formula. This series resistance is compared with that of Taylor series and other fine full-scale ships. An example given in this paper shows how to use the design charts.

长江客货船船模系列试验的主要对象是长江干线双桨客货船。对长江短途区间班轮和船型类似的内河船舶,也可参考使用。其船型参数范围如下: δ:0.52~0.64 L/B:4.6~7.0 B/T:3.6~6.0 文章给出了船型和阻力两套主要图谱。阻力图谱在F_n=0.20~0.32的范围内,以剩余阻力系数C_R形式给出。此外,还给出了当设计船舶的水线面系数和系列船型的水线面系数不同时的型值修正值和阻力修正图谱,以及变化吃水状态的阻力修正曲线。所有阻力图谱均用ITTC相关线计算摩擦阻力。文中也给出了将系列船型的阻力值转换到用柏兰特-许立汀(Prandtl-Schlichting)摩擦公式的转换方法。文章还介绍了系列船型与优良实船以及泰勒(Taylor)系列的阻力比较。最后通过一个计算实例介绍了图谱的使用方法。
