摘　　要：以直动平底从动件盘形凸轮机构为例,根据选定的从动件运动规律,建立凸轮轮廓曲线的参数方程。在Lab VIEW软件环境中编写计算程序,输入相应的凸轮运动参数,运行程序并将计算凸轮轮廓曲线的结果显示在程序界面上,同时生成曲线坐标点的数据文件。将数据点坐标导入至Solid Works环境中,建立凸轮三维模型,并利用Solid Works Motion模块进行凸轮机构传动的运动仿真。运动仿真的结果表明从动件能够按照预期的运动规律运动,凸轮轮廓曲线的设计满足设计要求。与传统设计凸轮轮廓曲线方法相比,此设计方法能够大大提高计算精度与设计效率,并且具有操作简单高效,可定制性高,交互界面直观清晰等特点。Taking the direct-acting flat-bottom follower disc cam mechanism as an example in this study.Setting up the parametric equation of the cam profile curve according to the motion law of selected follower.Write the calculation program in the LabVIEW software environment and input the corresponding cam motion parameters.Then run the program and made the result of calculating the cam profile curve displayed on the program interface,at the same time generating the file of the data points coordinates.The data are introduced into SolidWorks environment to establish the 3D model of the cam and the motion simulation of cam mechanism is carried out by using the SolidWorks Motion module.The result shows that the follower can move in accordance with the expected law of motion and the design of the curve meets the design requirements.Compared with traditional design methods,this design method can greatly improve calculation accuracy and design efficiency and it has simple and efficient operation,high customizability,intuitive and clear interface and other features.
