摘要科技的进步推动内燃机行业的持续发展。连杆组作为内燃机运动机件中一个 重要组成部分在运动机件中有着承上启下的作用,它的好坏也将直接决定内燃机 的可靠性、寿命、经济性等。运用三维建模软件能对某中速柴油机连杆组进行建 模,这样可以更好的了解连杆组的各个组成以及其内外部结构。连杆组也由多个 零件组成包括连杆轴瓦、衬套、螺钉、等。对其建模时也要考虑它们之间的装配 关系。利用 UG 对其进行建模装配,从而更直观立体的了解连杆,熟悉其工作原 理,了解其运动方式。对其进行强度分析,在连杆的材料选择上是非常重要的, 这直接决定着你整个强度校核的正确性与可行性。连杆大头连接曲柄,小头连接 活塞由此在缸内做循环运动带动整个动力系统。在其结构强度分析上需考虑其运 动规律,从而分析出受力,继而对连杆的强度做出准确的判断。84810 毕业论文关键词: 中速柴油机;连杆组; UG 建模;强度分析 Abstract The development of the internal-combustion engine industry is promoted by technological advances。The connecting rod group as a part of the moving parts plays a very important role,which determines the reliability,life and economy of internal-combustion engine。Using of 3D modeling software,The connecting rod group of one medium speed diesel engine can be modelled。It can be understood the structure and composition of the connecting rod group better。The connecting rod group is made up of many parts,such as connecting rod bearing shell,liner bushing,bolt and so on。We need to consider the relationship of the parts。Using UG assemble connecting rod group,It can be understood more intuitively,familiar with its working principle and movement。It is very important to select the material of the connecting rod when it is analyzed the strength of the connecting rod group,which determines if strength analysis is right and doable。The large end of connecting rod connect crank,the small end of connecting rod connect piston,it does cycle moving for Driving the whole power system。When it is analyzed the strength of the connecting rod group,It should be considered its movement law,then analysis the stress and make the right judgment。 Keywords:Medium speed diesel engine,Connecting rod group,UG modeling,strength analysis 目录 第一章 绪论 1 1。 1 本研究课题的目的和意义 1 1。3 主要研究内容 5 第二章 连杆组简述与三维建模 6 2。1 连杆组的构成及其功用 6 2。2 连杆组的三维建模 7 2。2。1 连杆组的连杆主体绘制 7 2。2。2 连杆组其他零件绘制及其装配 15 第三章 连杆的强度校核 20 3。1 连杆运动学与动力学 20 3。2 连杆的强度校核 25 3。2。1 连杆小头强度校核 26 3。2。2 连杆杆身强度校核 29 3。2。3 连杆大头强度校核 30 3。2。4 连杆强度校核结论 32 结语 33 致谢 34 参考文献 (责任编辑:qin) |
