基于MATLAB柴油机供油凸轮型线设计

摘要

In this paper,the design method of diesel engine high pressure pump cam profile was studied,the cam profile design theory was written through the MATLAB software,and the simulation calculation was established based on MATLAB GUI interface.In this paper,cam profile design is divided into two parts,including main parameter design and cam profile design.Cam profile design is divided into five steps,in order to adjust the key parameters of the cam profile,and verifying the reasonability of the cam profile.The method can also be further expanded in engine high pressure pump design in the later work.%对柴油机凸轮型线的设计方法进行了研究,通过MATLAB软件编写了凸轮型线的设计程序,并利用MATLAB的GUI功能建立了仿真计算的交互界面.型线设计分为主要参数设计、型线设计两部分,型线设计又分成5个步骤,以方便调整凸轮型线设计的关键参数,以及验证型线设计是否合理.该方法可在以后的工作中进一步拓展,以方便发动机供油系统的设计.
