综合课程设计说明书题 目： WY100 履带式液压挖掘机 斗杆油缸液压系统设计 专 业： 交通建设与装备 班 级： 装备 1101 班 姓 名：******学 号：************指导老师：******精品文档---下载后可任意编辑摘 要液压挖掘机应用面广、使用量大，在工程机械市场占有很重要的地位。目前已成为工程机械第一主力机械。对于液压式挖掘机而言，其设计核心就是对液压系统的设计，由于工程作业环境条件恶劣，要求实现的动作复杂，于是它对液压系统的设计提出了很高的要求，其液压系统也是工程机械液压系统中较为复杂的。因此，对挖掘机的液压系统的分析设计对推动我国挖掘机进展具有十分重要的意义。本次课程设计是在基于工程机械液压传动、机械原理、机械设计等方面的理论知识上针对WY100 型液压挖掘机工作装置斗杆油缸部分的液压系统进行设计，同时采纳伺服先导操纵系统、结合人机关系原理，使其具有造型美观、操作舒适、性能稳定可靠、具备多种作业功能的特点。关键词：液压挖掘机，斗杆油缸，WY100ABSTRACTHydraulic excavator,a wide range of applications,the use of a large quantity,a very important position in the market engineering machinery,has now become the first main machines of mechanical engineering.For the hydraulic excavator,the core of designing excavator is hydraulic technique.Because of the bad working condition and complicated working movements of the excavator, it has high requirements for its hydraulic system.Since the excavator’s hydraulic system is the pretty complicated one in all constructional machine, the analysis and research of its hydraulic system make very important to promote the development of excavator.The task of curriculum design based on the theoretical knowledge of Hydraulic Transmission of Engineering Machinery, Theory of Machines, Mechanical Designing, etc, is the design of dipper cylinder hydraulic system for WY100 type hydraulic excavator. At the same time,adopting the servo pilot control system and combining with human-technology relationships make the exca...
