北京理工大学珠海学院 2020 届本科生毕业设计液压高频换向阀的设计液压高频换向阀的设计摘 要线性摩擦焊技术在国内外是较为先进的一种固相连接技术。焊机主要组成部分之一就是往复振动运动部件。液压往复振动的综合性能尤为出色。高频换向阀是为实现液压往复振动的关键部件。目前市面上的换向阀的设计多种多样,但都缺乏新意,能参考的案例较少,而且阀门的类型并没有太大的改变。为解决液压高频换向阀换向的问题,本人查阅了相关文献资料,并列举了换向阀的多种类型,并进行逐步剔除,以此择优选出换向阀的设计思路与设计方向。论文为在原有的液压高频换向阀设计基础上进行优化改进。其中参考了转管武器加特林的运动原理,在将其进行分析后,对加特林各组成部分进行拆解与组合,优化原有的设计思路,设计出更合理的液压高频换向阀。关键字:线性摩擦焊;转管武器;高频换向阀北京理工大学珠海学院 2020 届本科生毕业设计北京理工大学珠海学院 2020 届本科生毕业设计Design of hydraulic high frequency directional valveAbstractLinear friction welding technology is a relatively advanced solid-phase connection technology at home and abroad.One of the key parts of the welding machine is the reciprocating vibration moving parts.The comprehensive performance of hydraulic reciprocating vibration is particularly excellent.The high frequency directional valve is a key component to realize hydraulic reciprocating vibration.There are many designs of directional valves on the market,but they lack new ideas.There are few cases that can be referenced,and the type of valve has not changed much.In order to solve the problem of hydraulic high-frequency reversing valve reversing,I consulted relevant literature and listed various types of reversing valves,and gradually eliminated them,in order to select and optimize the design idea and direction of the reversing valve.The thesis is to optimize and improve on the basis of the original hydraulic high-frequency directional valve design.Which refers to the movem...
