The paper employs the theory of the layout, design and function of the automatization manufacturing system and studies on the practice and process of cylinder of automobile in the Chang An Corp. author improve on the process the JL472Q, JL 474Q and 1L475Q cylinder to make a flexible manufacture line for the three kinds cylinder. The line composes nine facility (five horizontal machine center, two specific machine), two automatic lines. The FMIL have high utilizable ratio, stable throughput, and good reliability and solve the bottleneck in the process the cylinder of automobile. It contends Chang An corporation for enlarging production and entering into the WTO with quickstep.

本文针对长安汽车集团公司JL72Q、JL474Q、JL475Q三种汽车气缸体的加工工艺特点并结合工厂生产实际，对缸体的加工工艺进行了系统的研究改进，依据现代自动化制造系统的规划、设计和运行原理对三种气缸缸体的机械加工柔性自动线进行了总体设计，规划出了一条缸体机械加工柔性自动线，该自动线采用了9台加工设备(其中5台卧式加工中心，2台专用机床)，2条自动线的设计方案，整个柔性加工线设备利用率高、生产能力稳定、可靠性好，解决了企业生产中的发动机气缸体加工的瓶颈问题，适合长安汽车集团企业扩大生产与率先进入WTO战略的需要。

To validate the FEM calculations of the cylinder block of a six-cylinder in-line diesel engine,the dynamic strain-stress and temperatures of the main bearing wall s and caps were measured on engine testbed with strain-gauge and resistance thermometer.

为评估某直列6缸柴油机缸体有限元强度分析结果，采用应变电测法实测了该发动机缸体上可能的危险部位主轴承座、主轴承盖动态应力以及这些部位的温度。

The paper introduces the state of hydraulic cylinder voidance ,by contrast adoptting bore enlarge repair cylinder.

介绍了液压缸体的失效状况，通过对比采用扩镗方法修复缸体，并介绍了液压缸体扩镗的工艺过程，对其进行强度验算。

The invention discloses an apparatus of high pressure collecting hardened concrete solution in hole which is consisted of a cylinder body, a piston moving up-and -down in the cylinder body, under the piston, sealing gasket cooperating hermetically with the cylinder body, a brace table under the cylinder body, and a endless displacement tank on the edge of the cylinder body formed by which and the brace table, which linking to solution in hole collecting device by tubing guide.

本发明公开了一种高压收集硬化混凝土孔溶液的装置，包括一个缸体和一个可在缸体内上下运动的活塞，在所述活塞下方设有与所述缸体密封配合的密封垫片，所述缸体下方设有一支撑台，所述缸体与所述支撑台在所述缸体内径边缘形成一环状排液槽，所述环状排液槽通过导流管与孔溶液收集装置相连。

Introduces the technical process of hydraulic support cylinder bore enlarge,and give checking strength for it.

介绍了液压缸体的失效状况，通过对比采用扩镗方法修复缸体，并介绍了液压缸体扩镗的工艺过程，对其进行强度验算。

The end linking the timing gears cap, the side wall of cylinder and the skirt section of the engineblock are the sound radiation resources of the two engineblock sides. Except that, this thesis calculates sound power level of radiated noise from the engineblock with MATV method. It is found that the noise radiated from the engineblock is slightly loud.

此外本文还应用MATV法计算了气缸体辐射噪声的声功率级，通过声功率级的计算发现：气缸体的辐射噪声偏高，达到了108.84dBA，并且在850Hz时，由于气缸体的激励频率与其第八阶固有频率相等，气缸体发生了共振，因而在该频率时，气缸体的辐射噪声最大，所占气缸体表面辐射噪声总能量比重也最高，该频率应该是本文噪声控制关心的重点。

According to analysis the speciality of HR engine block and compare machine process from difference maker,this paper decides the technology specification of the machine line and give the machine process,it introduces how choose machine equipment specification and what new technology are used.
