摘　　要：计算机仿真技术在机械工程、自动化控制工程、国防建设等领域得到广泛的应用,已成为研究、设计和分析复杂问题的重要工具。文中首次将计算机仿真技术引入超硬材料加工技术,从运动学和几何学原理出发,建立了双摇杆机构的数学模型,得出了双摇杆机构中工件中心点的运动轨迹方程,并用VisualBasic语言编制了相应的计算机仿真软件,以图形的形式显示出了运动轨迹曲线。并对各杆的长度及相角度等设计参数进行了优化,并将其成功地应用于立方氮化硼等超硬材料的抛光技术。As an important tool to research, design and analyze the complicated problems, the computer simulation technology has been employed in many fields such as mechanical engineering, automatic control engineering and national defense construction. The computer simulation technology was applied firstly in the precision machining process of superhard materials. On the basis of kinematics and geometry principle, the mathematical model for the double rocker arm mechanism was established. The movement path equation of the workpiece center point on the double rocker arm was derived. The computer simulation software was developed and the path curve was figured by using Visual Basic language. Before the double rocker arm mechanism was applied in the machining process, the length of varies arms and their correlative angles were optimized. The best parameters combinations which can fulfill the application requirement were found. The optimal mechanism was applied in the polishing process of superhard material.
