摘要 摘要 液压传动在机械传动中可以说是一门新技术，但是假如从1650年帕斯卡提 出的静压传递原理后开始计算的话，也有几百年的历史了。而经过这么多年的发 展液压传动在某些领域相对于机械传动已经占有了压倒性的优势，因此液压传动 在传动领域占到的比例，已经成为反映一个国家工业水平的重要特征之一。 我国的液压工业起步较晚，但从20世纪80年代开始国家已经开始加速对国 外先进技术的引进、学习、吸收和国产化的过程，这就扩大了国家对液压人才的 需求，而各个高校也展开了 《液压传动》这门课程的教学。QCS003液压教学试 验台就是在那时被各大高校引进的，并从此开始成为了液压教学中理论与实践结 合的一种常用方式。 本文通过对液压缸的设计计算，利用液压缸的的具体参数来对整体系统中的 管道、油箱的设计计算，从而对各个液压元件来进行选型，最后利用原实验台进 行液压泵的性能实验，并画出相应的曲线图。 关键词：液压缸、溢流阀、电磁换向阀 I Abstract Abstract Hydraulic transmission in mechanical transmission can be said to be a new technology,but if the static pressure transfer principle from the 1650 Pascal after the beginning of the calculation, there are several hundred years of history.And after so many years of development of hydraulic transmission in some areas with respect to the mechanical transmission has occupied the overwhelming advantage, so the hydraulic transmission in the field oftransmission accounted for theproportion ofhas becomereflect acountryslevel ofindustrial isone ofthe important characteristics. China hydraulic industry started relatively late, but from the 80s of the 20th century began to countries have begun to accelerate the introduction of foreign advanced technology, learning, absorption and localization process, which expanded the national demand for hydraulic talents, and various colleges and universities also launched a hydraulic transmission in the course of teaching. QCS003 hydraulic teaching test bench wasintroduced at that time by themajor universities,andbegan to become a combination of theory and practice in the teaching of the theory and practiceofacommon way. In this paper, the calculation of the hydraulic cylinder design, the use of hydraulic cylinders of specific parameters to calculate t
