高空作业车改装设计

摘要

高空作业车是目前最常见的专用汽车之一。由于高空作业车近几年的快速发展，高空作业行业出现了部分车型产量过剩苗头的同时，也存在着部分车型供不应求、生产能力不足的现象，因此，结构性过剩是当前汽车工业产能过剩的基本特点，也是当前汽车工业发展存在的主要问题。高空作业车是汽车工业的一部分，它的发展中也会出现同样的问题，因此研究高空作业车的改装技术，不仅可以推动高空作业车行业的发展，而且对于推动专用汽车行业的发展，调整企业产品开发战略无疑具有重要意义。在这次的设计工作中,我主要设计了一种折叠臂的高空作业车,主要以上、下臂，转台，液压部分为研究对象。

本设计主要设计的是作业高度为10米的高空作业车，在满足作业高度的前提下，对高空作业臂，转台，液压部分进行设计：首先根据使用要求选择作业臂材料的类型；其次根据最大作业高度确定上、下臂的长度；再经过受力分析利用强度来确定臂的截面尺寸及油缸的铰接位置；再进行强度、刚度、稳定性的校核，查看作业臂的尺寸是否符合要求；转台和液压部分同样原理也要进行计算与校核。

ABSTRACT

Operating vehicle height is the most common one of the special vehicle.In recent years,because the aerial work vehicle the rapid development,aerial work industry appeared part models yield,but also excess symptom exist in demand,production capacity part models,therefore,the phenomenon of insufficient structural surplus is the auto industry excess capacity,but also the present the basic characteristics are the main developing automobile industry.Aloft work vehicle is part of the auto industry,and its development will also be the same problem,so the aloft work vehicle modified technique,not only can promote the development of the car industry aerial work,and to promote the development of specialized automobile industry,adjust enterprise product development strategy of great significance.In this design work,I design a folding arm of the high-altitude vehicles.Main above,upper and lower arm,turntable,hydraulic parts as the research object.

This design main is the height of10meters aloft work vehicle,to meet the high operating on the premise that for aloft work arm,turntable,hydraulic parts design:First choice under the requirements of the use of operating arm of the types of materials;Second, based on the height of the largest operations to determine the upper and lower arm length; After Analysis to determine the intensity of use of the arm section size and fuel tanks articulated position;further strength,stiffness,Stability of Verification,check the operating arm size whether it meets the requirements;Turntable and hydraulic parts also principles want to calculate and checking.

Key words:Aloft work vehicle；Aloft work arm；Turntable；Hydraulic system；
