摘 要
我所设计的ZL15装载机既保留了传统装载机的优点，而有具有新的性能和优点。
本次设计主要进行的工作装置的设计。装载机采掘和卸载货物的作业是通过工作装置的运动实现的。装载机的工作装置由铲斗，动臂、摇臂、连杆及液压系统等组成。铲斗以铲装物料；动臂和动臂油缸的作用是提升铲斗并使之与车架连接；转斗油缸通过摇臂，连杆使铲斗转动。动臂的升降和铲斗的转动采用液压操作。
先对装载机的发展概况几设计的指导思想、特点、任务进行概述，然后确定方案，在技术设计部分罗列了ZL15装载机的主要技术性能和参数，进行了牵引特性计算，工作装置设计。工作装置设计中有工作装置运动分析，对铲斗、动臂、连杆机构进行设计等几部分组成。
在工艺设计中叙述了工艺工程。应用程序计算了受力分析。总之，整个设计是有序地完成的。
在整个设计的过程中，在老师及其他老师的指导下顺利完成的，通过这次设计，我学到很多东西，在实践中把大学中所学的知识综合运用复习了一次，同时也学到很多新的东西，受益非浅。在此，本人表示衷心感谢！并真诚希望各位老师对我提出宝贵的意见。
Abstract
This type of ZL15 loader that I have designed has the common virtues of the traditional loaders.And it has some new-improved virtues and function.
In my design progress,I put emphasis on the working-device.
The ZL15 loader also has some traditional virtues like the articulited wheel-type loader.The loader digging and unload the goods by the working-device.The working-device has many
Parts and it is connected to the machine.Some parts of the device’s turning by liquid press realize.
At first,I introduce the developing trend of the loaders,and explained the main designing idea, designing characteristic and designing task.The second part is the whole designing prgram.In the technical designing part,the main technological parameters and technological features of the ZL15 loader are listed.The following part is the calculation part of the tractive features and the designing of the working device.
The necessary computer progress is placed in the end of my designing progress,all the computer program was composed with C language .In a word,the whole designing progress is designed carefully and step by step.I wish my design could clearly explained my designing idea.
With the kind help of Mr.LiFeng and other teachers,I finished my design successfully.Through designing this type of ZL15 loader,I have attained a lot which was new to me.Here,I want to express my heartful gratitude to those teachers.At the same time ,the shortcomings in my design need to be poingted out by the teachers.thank you all.
