1、 1 摘摘 要要 在我国，汽车起重机发展已有六十多年的历史了，由于受到客观条件的限制，一 度发展较慢，进入九十年代发展迅速，但与国际先进水平还相差很远，主要表现在产 品质量的稳定性，自动化，智能化等方面。随着经济建设的迅速发展，我国的基础建 设力度正逐渐加大，道路交通，机场，港口，水利水电，市政建设等基础设施的建设 规模也越来越大，汽车起重机的市场需求也随之增加。 本文是对 QY16U 型汽车起重机的吊臂伸缩机构进行设计，确定吊臂主要尺寸、 质量参数，确定各部件、总成的相互位置关系，利用 Solidworks 完成 QY16U 汽车起 重机吊臂伸缩机构的三维实体装配模型，利用 Ansys 对结

2、构件进行强度校核，对确定 中、小型汽车起重机的设计方案具有很强的现实意义。 关键词：汽车起重机 ；吊臂 ； 伸缩机构 2 ABSTRACT The design and production of the truck crane have more than 50 years history in our country. The development of truck crane, however,has slowed down for some objective reasons. Since 1990s, it was accelerated in our country, but t

3、he products still could not reach the advanced international level in the quality stability, autnation, and intelligent. With the rapid development of economic construction, Chinas infrastructure is gradually improving the intensity. Road traffic, airports, ports, water conservancy and hydropower, m

4、unicipal construction of infrastructure such as the scale of construction is also rapidly growing. Crane truck crane market is also on demand with the increase. The thesis is the study of the type of truck crane QY16U design and the discourse upon choices of Telescopic crane agency. The overall layout and stability, the design of the lifting mechanism and calculation methods. It is also discussed chiefly concerns with how to determine the whole machine size , quality parameters, and how to
