山东交通学院 2014届毕业生毕业论文（设计） 题目：我国挖掘机发展简史 院（部）别 专 业 级 机升121 学 号 姓 名 指导教师 张铁 二○一四年六月 摘 要 本文主要介绍了我国工程机械行业的一些基本状况，特别是挖掘机的发展简史。其中重点叙述了挖掘机的结构、分类以及应用领域，还有挖掘机的发展历程等，并对挖掘机的未来发展道路做出了预测。 1954年，我国第一台机械式单斗挖掘机在抚顺挖掘机厂问世，从此打破了我国无挖掘机的市场。从那以后，我国挖掘机行业的发展大致经历了测绘仿制、自主研制开发和发展提高等三个阶段。在这几十年的风雨历程中，我国的挖掘机行业不断的发展壮大，到了20世纪80年代末，已经拥有了30多家生产厂家。改革开放以后，我国又积极的引进国外的先进技术，吸收精华，使得我们的科技力量更加的雄厚。到了21世纪，我国的挖掘机行业已经走入世界领先阵营，成为了令国人骄傲的一大产业。 任何事物的发展离不开刻苦奋斗的精神，也离不开长期积累的文化底蕴。希望我国的工程机械行业在国际上发展的越开越强大，以最精湛的高科技水准呈现给世界。 关键字：挖掘机、发展、工程机械 Abstract This paper describes some of the basic situation of Chinas construction machinery industry, especially the development of a brief history of the excavator. Which focuses on narrative structure of the excavator, classification，application fields, the development of excavator and the future development path excavator made ??a prediction. In 1954, Chinas first mechanical shovel excavator plant in Fushun advent of breaking free from the excavator market. Since then, the development of Chinas mining industry has gone through and mapping imitation, independent research and development to improve the three stages of development and so on. In these decades of ups and downs in our excavator industry continues to grow and develop, to the late 1980s, already has more than 30 manufacturers. After the reform and opening up, China has been actively introducing foreign advanced technology, absorb the essence, making us more strong scientific and technological strength. In the 21st century, Chinas excavator industry has entered a world leader in the camp, became the pride of a large industry. Inseparable from the development of anything spirit of hard struggle, but also inseparable from the long-term accumulation of cultural heritage. I hope Chinas construction machinery industry in the international development of the more open the more powerful, the most exquisite high-tech standards prese
