摘要: 螺旋桨曲面为高阶自由曲面,故以四丝束碳纤维螺旋桨曲面铺放装置为平台,进行了碳纤维铺放成形轨迹规划的研究。依据船用定距桨桨叶曲面轨迹规划的要求,针对传统曲面网格和轨迹铺放法的低精度缺陷,提出了基于拉普拉斯网格优化、等弧长曲面分层的轨迹优化铺放算法,并完成了算法仿真和实物验证。结果表明,该轨迹规划方法能满足碳纤维螺旋桨的铺放要求。

Abstract: Because the propeller surfaces are high-order free form surfaces, trajectory planning of carbon fiber placement and formation was carried out with four-wire carbon fiber screw propeller surface placement device as platform. According to the requirements of surface trajectory planning of marine fixed pitch paddle blades, a trajectory optimization placement algorithm, aiming at low-precision defects of traditional curved mesh trajectory and placement method, was proposed based on Laplacian mesh optimization and equal-arc length surface stratification, and the algorithm simulation and physical verification were completed. Results show that the trajectory planning method may meet the placement requirements of carbon fiber screw propellers.

Key words: carbon fiber, screw propeller, grid optimization, trajectory planning
