To solve cylinder liner crack problem of a certain large marine diesel engine , the crack was studied and analysed being aimed at the cylinder liner which created the crack by means of colouring crack detection , electron microscope scanning , energy spectrum analysis , chemical composition analysis and so on . also the temperature distribution and the stress condition of the cylinder liner were researched and analysed utilising measurement on board ship and finite element analysis method . finally the main causes of the cylinder liner crack were synthetically analysed and determined 为解决某大型船舶柴油机气缸套裂纹故障问题，利用着色探伤、电子显微镜扫描、能谱分析、化学成分分析等方法对其裂纹进行了研究分析；并利用实船测试、有限元分析等方法对该型缸套的温度分布状况、应力状况，进行了研究分析.确定了缸套开裂的基本原因
The old control system mainly using - and - now ca n ' t meet the high and complicated requirements of modern ship to control its boiler . it is imperative under the situation to use computer for ship control area . and the remarkable plc used currently by industry process control area is the most reliable , simple and convention way to realize computer control on board modern ship . the paper introduce simply the basic principle of plc and the characteristic of simens plc s5 - 115u and a typical boiler system of huge oil tank . on this base , the paper pay more attention to making control programme of s5 - 115u for huge marine fuel oil boiler . and pid control method is singly adopted for water level control and steam pressure control of the fuel oil boiler 以继电? ?接触器为主的老一代控制系统已不能满足现代船舶对其锅炉控制的越来越高、越来越复杂的要求，这一领域的计算机化已势由必行，而应用在当前工业过程控制领域中引入注目的可编程序控制器( plc )又是使其计算机化的最简便和可靠途径。本文主要介绍可编程序控制器( plc )的基本工作原理、德国西门子可编程序控制器s5 - 115u和大型油轮锅炉的典型系统，在此基础上对用西门子s5 - 115u控制大型船舶燃油锅炉进行了编程。
Analyzing the tugboats " number and horsepower marshaling mode in tianjin port , based on the development of throughout in 2005 ( which may be 140 millions ton ) and the requirement of 150 , 000 - ton - shipping putting in and leaving the port ; 2 . how to organize the marshaling structure of tugboat - fleet to adjust the requirement in 2010 , when the throughout of tianjin port will come to 200 millions ton ; 3 . studying the change of the tugboat utilization ratio and the influence of the whole layout of tugboat - fleet , in accordance with the change which shipping putting in or leaving the port will be random and need n ' t concrete operation , along with widening the port - lane and allowing the two - way shipping 同时对天津港的吞吐量发展及大型船舶进出港的趋势进行了分析，并把拖轮营运与港口生产的发展结合起来，对下述问题进行具体分析： 1 、结合天津港2005年吞吐量的发展( 1 . 4亿吨)以及15万吨级船舶进出天津港的需求，分析对港口拖轮的数量和马力配置； 2 、拖轮船队的结构如何适应2010年天津港吞吐量将达2亿吨的要求； 3 、随着天津港航道的不断拓宽，双向航行将被允许，进出港船舶可随时而无须集中进行。
This paper conducts simulation experimental research on channel navigation area using large - scale ships operation simulator , including the ships ' danger under different wind , wave and flow conditions and safety appraisal result , time needed for entering and leaving port , and recommends the reasonable width of waterway , so as to provide reliable basis for engineering structural design and working - out of ships - operation regulations 摘要利用大型船舶操纵模拟器对航道航行水域进行模拟试验研究，包括不同风、浪、流等环境下操船危险度及安全评价结果，进、出港所需时间，并推荐航道的合理宽度，为工程结构设计和操船规程的制定提供可靠依据。
