【摘要】：本文首先介绍了凸轮在各个领域的重要性,阐述了计算机辅助设计(CAD)技术在提高设计生产效率等方面发挥的重要作用,分析了目前国内外针对凸轮设计的CAD系统存在的专业性不强等问题,提出开发凸轮连杆组合机构CAD系统的必要性,因此对基于SolidWorks的凸轮连杆参数化设计及CAD系统开发进行了研究。1.凸轮连杆机构数学模型及运动规律分析。针对凸轮连杆组合机构的求解提出分级、分模块设计计算方法,为各类分级后的机构编制程序模块,实现求解程序的通用化,对凸轮连杆机构的运动规律曲线选用原则进行了分析与研究。2.凸轮连杆组合机构CAD系统开发。以SolidWorks为开发平台,Visual Studio2012为开发工具,VC++为编程语言,开发出一款针对凸轮连杆组合机构设计的CAD系统,并在选定适合的参数化方法后,实现对凸轮零件的参数化建模。3.对高速凸轮连杆机构进行动力学分析。讨论高速凸轮的惯性冲击对执行末端精度的影响,理论分析了影响凸轮驱动部分的振动因素,在此基础上就如何控制凸轮机构振动提出建议,并将部分减振措施融入到了开发的凸轮连杆组合机构CAD系统中。
[Abstract]:This paper first introduces the importance of cam in various fields, and expounds the important role of CAD in improving the efficiency of design and production. This paper analyzes the problems existing in the CAD system designed for the cam at home and abroad, and points out the necessity of developing the CAD system of the cam connecting rod combination mechanism. Therefore, the parameterized design of cam linkage based on SolidWorks and the development of CAD system are studied. 1. The mathematical model and motion law of cam linkage mechanism are analyzed. Programming modules are compiled for all kinds of graded mechanisms to realize the generalization of the solution program. This paper analyzes and studies the principle of choosing the curve of cam linkage mechanism. 2. The development of CAD system of cam linkage combination mechanism. Taking SolidWorks as the development platform and Visual Studio2012 as the development tool, VC is used as the programming language. This paper develops a CAD system designed for the cam and connecting rod combination mechanism, and after selecting the suitable parameterization method, The parameterized modeling of cam parts is realized. The dynamic analysis of high-speed cam linkage mechanism is carried out. The influence of inertia impact of high speed cam on the precision of execution end is discussed, and the vibration factors affecting the driving part of cam are analyzed theoretically. On the basis of this, some suggestions on how to control the vibration of cam mechanism are put forward, and some damping measures are integrated into the CAD system of cam linkage combination mechanism developed.
