Error Analysis of Scribing Trajectory for Parallel Scribing Device Based on Monte-Carlo Simulation

  • 摘要: 提出了一种基于并联机构的划线装置。按运动学方程微分法和误差独立原理,建立单一影响因素下末端划线头的位置综合误差模型,并利用蒙特卡洛法对两种误差模型进行了模拟分析。结果表明:装置划线综合位置误差范围为0~7.5×10-3 mm,其中,仅考虑杆长误差时,综合位置误差范围为0~4×10-4 mm;仅考虑转动副间隙误差时,综合位置误差范围为6×10-5 mm~9.5×10-5 mm。划线综合位置误差受多个因素影响,但以驱动杆杆长误差影响较大,且并非简单地为各个因素的叠加;同时两种误差建模方法相结合的分析方法可全面系统地分析机构末端的综合误差。
