基于复杂类回转体90°纤维轨迹规划算法研究

RESEARCH ON 90-DEGREE FIBER TRAJECTORY PLANNING ALGORITHM BASED ON COMPLEX ROTARY SURFACE

铺放轨迹设计是控制自动铺丝工艺质量的关键,为进一步提高复杂类回转体复合材料构件轨迹铺放质量,提出以类回转构件的形心曲线为基准参考线,综合考虑角度偏差、轨迹间距及轨迹测地曲率的多目标轨迹规划算法。根据丝束宽度、丝束数量等工艺参数生成满足工艺要求的基准轨迹,通过对基准轨迹偏移生成偏移轨迹并对其进行局部调整和全局优化,设计其他轨迹。最后以Visual Studio 2010为开发平台,利用CATIA Automation技术开发了复杂类回转体铺放软件,并在复杂类回转体曲面上进行了验证,结果证明了该算法的有效性。

The design of the automated fiber placement trajectory is the key to control the quality of the trajectory laying process.In order to further improve the laying quality of complex rotary surface,a multi-objective trajectory planning algorithm,which takes the centroid curve of the similar rotating component as the reference line and considers the laying angle,trajectory spacing and trajectory curvature comprehensively,was proposed.The reference trajectory,which meets the process requirements such as the width and the number of the tows,is designed.The other trajectories are designed by locally adjusting the offset trajectory and globally optimizing.Finally,the CATIA secondary development technology is used to realize the software of trajectory planning for complex rotary surface on Visual Studio 2010 platform.It is verified on the complex rotary surface and proves the effectiveness of the algorithm.
