【摘要】 本文针对国内高空作业车的生产技术水平落后于国外的现状,在对国内外高空作业车的关键技术及发展趋势认真分析和对比的基础上,结合客户的实际需求,消化吸收国外先进技术,对TLK21型高空作业车的液压驱动系统、调平系统和微电控制系统展开设计研究。本文首先在分析比较国外同类型的产品的基础上,设计了TLK21型高空作业车主要执行装置和机构的液压驱动系统,其中包括转向装置、回转装置、伸缩臂变幅装置等等。由于系统要求的控制量较多,而且多个控制量要求采用电液比例控制,因此系统采用了负载敏感式比例多路阀对主要执行元件进行控制。然后针对该车的行走液压驱动系统展开深入研究,因为它是该车需要解决的关键技术之一,直接影响到车辆的机动性能。接下来采用MATLAB仿真和机械最优化设计的方法对该车的作业斗调平机构进行设计,通过误差分析证明得到的设计结果是最优的。最后,将CAN总线技术引入到该车微电控制系统中来,设计了该车微电控制系统的硬件网络,并完成了电液控制程序的编写。目前,所设计的全液压驱动自行式高空作业车已经安装、调试完毕,并已交付用户使用。该车在实际生产中达到了预期目标,提高了生产效率,取得了一定的经济效益。更多还原

【Abstract】 Aiming at condition that the internal technical level of aerial work platform is lower than the external one, and based on analysis and comparison of the key technology and the developing tendency of the external aerial work platform, this paper designed hydraulic system, horizontal adjustment system and electric control system of TLC21 type of aerial work platform according to customer’s acquirement and external advance technology.Firstly, based on analysis and comparison of external alike productions this paper detailedly introduce the design of main apparatus and hydraulic drive system including of steering apparatus, turning apparatus, telescopic arm apparatus etc. Because there are many apparatus that must be controlled and some of apparatus need electro-hydraulic proportional control, load-sensing proportional sandwich valves are applied to control main apparatus in this system. And then research of driving hydraulic system is carried out, because this is a key technology that must be solved. Afterward, Horizontal adjustment apparatus is designed with MATLAB simulation and mechanical optimization design methods. Finally, CAN-BUS technology is applied to electric control system, hardware network of electric control is designed and programs of electro-hydraulic control are finished.At present, the entire hydraulic drive engineering aerial work platforms have been provided to customer after assembled and debugged by Tonglian Company. The vehicles have achieved the anticipated goals, improved the producing efficiency and obtained the considerable economic profit.更多还原
