优秀设计
摘要
一台较为先进的柴油机,不仅要有先进的性能指标,而且还要有足够的寿命和可靠性。6110型柴油机就是针对配备大型货车而进行开发和研制的同时也可用于发电机组、工程机械和船舶。该机型噪音低,排放好,功率大,结构紧凑,启动好,烟度小,经济性好,燃油消耗率低。原机型主要用于城市间的长距离运输,对于城市交通路况需要重新设定参数,以改善燃油经济性和排放性能。柴油机的总体布置和各附件的布置对内燃机的外形尺寸和工作可靠性、使用方便性都有很大的影响。应在保证拆装、维修方便的前提下,尽可能直接可靠地固定在机体和气缸盖上,并且不使任何附件过于突出。尽量不用外接的机油管和冷却液管,而采用在零件上开通道代替,以减少泄露的可能。减少零件数不仅改善了其可靠性,而且有利于降低成本。本课题对活塞进行了详细设计和分析验算,并给出了合理的设计方案。

Abstrac
A more advanced diesel engines, not only have a state-of-the-art performance, but also to have the life and reliability. X6110 type diesel generator set, construction machinery and ships can also be used for research and development, with large trucks. The model has low noise, emissions, power, compact, good start, smoke a small, good economy, low fuel consumption. The original model is mainly used for long-distance inter-city transportation, the need to re-set the parameters for urban traffic conditions, in order to improve fuel economy and emissions performance. The overall layout of the diesel engine and attachment size and shape of the layout of the bustion engine reliability, ease of use are greatly affected. Should ensure that under the premise of convenient disassembly, repair, and as directly as possible to reliably fixed in the body and the cylinder cover, and any attachments are too. As far as possible without external oil pipe and the coolant tube, while the use of open channel instead of on the part to reduce the possibility of leakage. Reduce the number of parts not only to improve its reliability, but also help to reduce costs. This topic on the piston of the detailed design and analysis of checking, and gives a reasonable design.
Key words: 6110, six cylinder, diesel engine crankshaft, piston design, design
前言
选题背景和意义
柴油机的发展,已经有八十多年的历史。通过这一长时期的不断改进和提高,已经发展到了比较完善的程度。由于他的热效率高、适应性好、功率范围广,已经广发应用于农业、工业、交通运输业和国防建设事业。因此,柴油机工业的发展对国民经济和国防建设都具有十分重要的意义。
就当前各国动力机械的发展情况来看,在现有各种原动机中,包括蒸汽轮机、燃气轮机、水轮机柴油机、汽油机、煤气机以及核动力装置等,其中蒸汽轮机和核动力装置主要用于大型固定式电站、大型远洋航轮和军用舰艇上。水轮机多限于水
