摘要:(摘要内容经过系统自动伪原创处理以避免复制,下载原文正常,内容请直接查看目录。) 本课题起源于年夜连辽渔团体修船坞为三艘俄国渔轮(“特伯里”、“达娜夫”、“霍达卡”号)改换主动员机后的轴系改变振动研究课题。在该项目中,自动力装配轴系改变振动风险水平切实其实定相当主要。对于远洋捕捞功课的船只,俄语论文网站,这直接关系到其平安性、靠得住性及船舶轴系的寿命。本文剖析了我国轴系改变振动研究的情形及与世界先辈程度比拟较的差距;简略引见了改变振动的一些实际和盘算办法。编写了一套可通用于各类型内燃机轴系自在改变振动、强迫改变振动盘算的软件。并以“特伯里”号为实例停止了盘算。用盘算成果数据做校核盘算,俄语论文网站,并与俄罗斯列宁格勒年夜学供给的盘算解释书停止比拟,得出结论。 Abstract: The origin of this topic on the eve of the even Fishery Group dock for three Russian fishing vessel ("Waterbury", "Dana husband", "Huo Dhaka"), change the active engine shafting change vibration research. In this project, the automatic force assembly shaft system changes the risk level of vibration effectively. About ocean fishing lessons ships, which is directly related to the safety, reliability and life of shafting. This paper analyzes the situation of the research on the vibration of the shaft system in our country and the gap between the world's ancestors and the world's advanced level. A set of software which can be used in various types of internal combustion engines to change the vibration and force to change the vibration. And to "Waterbury" as examples to stop thinking. With the calculation results of the data do checking calculation, and calculation and the Russian Leningrad university provides instructions to carry on the comparison, a conclusion is drawn. 目录: 引言 6-7 第一章 船舶轴系简介 7-9 1.1 船舶轴系的组成与布置 7 1.2 船舶轴系的激振力 7-8 1.3 船舶轴系扭转振动的危害 8-9 第二章 扭转振动的基本理论和计算措施 9-18 2.1 扭转振动的基本理论 9-11 2.2 扭转振动的当量转化和计算措施 11-16 2.3 改善扭转振动的方法 16-18 第三章 船舶轴系扭转振动计算程序说明 18-28 3.1 程序流程框图 18-19 3.2 程序变量说明 19-21 3.3 轴系扭转振动程序(部分) 21-28 第四章 实例--PC-300型改装渔船振动特性理论计算 28-50 4.1 原始数据 28-29 4.2 计算结果 29-48 4.3 数据校合与对比略论 48-50 第五章 结论 50-51 附录 “特伯里”号渔轮推进轴系扭转振动测试报告 51-63 参考文献 63-64 致谢 64 |
