【正文】 r try to show the working principle of Hydraulic system vividly and finally try to provide a product which is easy to use for learns of this course. In this paper, the hydraulic circuit of truck crane Q28 was choosed. The author firstly simply intrduce some basic information of the truck crane Q28. Then analyzed the situation of every part of hydraulic circuit of all functional circuits. Luffing loop and lifting loop was choosed to be analyzed in detail , The autor give out the static and dynamic analysis of the two circuits ahead. And then choose the right hydraulic ponents of the circuits according to the design manual. In this way, the simulation work bee more close to real application, the author also consolidate the mastery of this course at the same time. Finally, the author introduce the method to make the animation bine the process that i make this animation. Key words : Q2 truck crane、 hydraulic circuit、 analysis、 Flash、 simulation 目錄 目錄 摘 要 ..............................................................................................................................
