摘要
研究了从CATIA数字模型中获取凸轮轮廓曲线上离散点坐标的方法,并以这些离散点及凸轮机构基本尺寸为依据,提出了反求机构从动件的运动规律的方法。利用CATIA提供的COM功能,结合其自带的V5AutomationAPI函数开发了反求从动件的运动规律算法及程序,并对反求所得结果与理论结果进行了误差分析,研究表明提出方法是准确的和适用的。
The method to obtain the coordinate values of discrete point on the cam profile from the numerical model of CATIA are studied, The method for the motion regulation of the cam follower are provided on inverse design by use of given discrete point and the basic size of cam, The COM technology of CATIA and V5 Automation API function are provided, the program of the cam follower anti - resolve Kinematics analysis procedure are developed, The error between the measure results and the theoretic results are analyzed, The result shows accuracy and applicability.
