------------------摘要
后装压缩式垃圾车是用于城镇袋装、桶装、散装生活垃圾物的收集、运输、卸料作业的专用车辆.后装压缩式垃圾车的装载容积和装载质量,取决于车厢的容积和垃圾被压缩的程度,即压缩比.其中压缩装置是整个垃圾车工作装置的关键部分,其性能直接影响到整机的工作性能.
论文的主要工作如下：
1、 通过压缩装置型式的综合分析和方案的优选,确定压缩机构的最终方案；通过计算确定压缩装置的装填角.
2、 根据机构运动相关参数选定液压油缸,根据初始运动条件确定系统压力.
3、对压缩机构装配体进行运动仿真分析,绘制油缸铰接点受力分析表及曲线图,绘制导轨上下表面受力分析表及曲线图,绘制液压油受力分析表及曲线图.并根据所有数据校核关键零部件.
上述工作有助于对后装压缩式垃圾车的工程设计与改进,对产品的研发和提高产品质量有着重要指导意义.

After the truck loaded compressed type is used for urban bags, bottled, bulk living garbage collection, transportation, which special vehicles unloading operations. The truck loaded compressed type after the load capacity and load capacity of the carriage, depending on the quality and junk compressed degree, namely compression ratio. Including compression device is the key part of the garbage truck working device, its performance directly affect the machine work performance.
This paper, the major work is as follows:
1, through the compression device types of comprehensive analysis and scenario selection, determine the ultimate solution; compressed institutions Through the calculate and determine the loading Angle compressed device.
2, according to related parameters selection mechanism motion hydraulic cylinder, according to initial movement condition fixing system pressure.
3, on compression institutions assembly body motion simulation analysis, drawing oil cylinder force analysis tables and hinged points, rendering guide fluctuation surface graph force analysis tables and graphs, drawing hydraulic oil stress analysis tables and graphs. And according to all data check key components.
The above work helps after roll-off garbage trucks loaded compressed to the engineering design and improvement of product research and development and improve the quality of products has important guiding significance.
Keywords: compressed type truck compression institutions optimization design simulation analysis
再问： 谢谢你啊，好人。
再答： 光谢谢我还不够啊，要采纳我的回答为最佳答案啊，坏人。
