摘要
针对齿轮五杆机构的可行域分析问题,将可动性理论与QT creator软件结合,开发一种计算机辅助设计软件,对标准位置下的多参数齿轮五杆机构的分支、分支点进行自动识别及分支纠正。首先利用判别式对齿轮五杆机构进行可动性理论分析;然后,利用QT creator软件搭建界面,设计齿轮五杆机构辅助设计软件。通过特征识别过程,软件自动获取机构的分支点及分支结果,对有运动缺陷的分支可通过调整齿轮机构传动比及初相角进行分支纠正。最后,利用齿轮五杆机构对分支点、分支的识别过程及分支纠正进行实例验证。结果表明,所开发的齿轮五杆机构辅助设计软件可方便快捷地进行机构可行域分析,提高了机械设计效率。
Aiming at the problem of mobility domain analysis of geared five-bar linkage,combining its mobility theory with“QT creator”software,a computer-aided design software is designed.This software can automatically identify correct the branches and branch points of the multi-parameter geared five-bar linkage under the standard position.Firstly,the mobility of the geared five-bar linkage is analyzed by the discriminant formula.Then,using QT creator software to build the interface,the geared five-bar linkage auxiliary design software is designed.Through the feature recognition process,the software automatically obtains the results of the branch points and branch of the linkage,and branches with motion defects can be corrected by adjusting the geared chain transmission ratio n and the initial phase angleβ.Finally,the branch point,branch identification process and branch correction of the geared five-bar linkage is verified by instance.The results show that the computer-aided design software designed can easily and quickly analyze the feasible region of geared five-bar linkage and improve the efficiency of mechanical design.
