Abstract:

Automation equipment was typically a strongly coupled, nonlinear, and flexible complex mechanical system, which made it challenging to establish an accurate kinematics model. A kinematics modeling method was proposed that integrated geometric deviations and gravity deformations for a large gantry automatic fiber placement machine. A theoretical kinematics model was developed based on multi-body system theory, the geometric deviations were analyzed in model coordinate conversion, and the gravity deformation-sensitive parts of the gantry fiber placement machines were studied. The gravity deformation matrix was obtained through mechanics abstraction and parameter extraction. The geometric deviations and gravity deformations were incorporated into the theoretical kinematics model to establish a comprehensive kinematics model of the gantry fiber placement machines. Parametric calibration was achieved through objective function establishment, measurement point selection, and parameter identification. Experimental results demonstrate that the proposed method may significantly improve the precision of the kinematics model, the position errors of the gantry fiber placement machines are reduced by over 74%.

Key words: gantry fiber placement machine, kinematics modeling, geometric deviation, gravity deformation, parameter identification

摘要:

自动化设备通常是一个强耦合、非线性且具备一定柔性的复杂机械系统,这使得建立该系统精确的运动学模型具有较大的难度。为此,针对一台大型龙门自动铺丝机提出一种综合几何偏差和重力变形的运动学建模方法。基于多体系统理论建立理论运动学模型,分析模型坐标转换中存在的几何偏差,研究龙门铺丝机重力变形敏感部位,通过力学抽象和参数提取得到重力变形矩阵,将几何偏差与重力变形有机引入理论运动学模型,建立龙门铺丝机综合运动学模型。利用目标函数建立、测量点选择、参数辨识等手段实现模型中的参数标定。实验结果表明,所提方法可有效提高龙门铺丝机运动学模型的精度,采用该方法后龙门铺丝机位置误差降低了74%以上。
