A Trajectory Planning Method for Automatic Placement of Carbon n Fiber Screw Propellers

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. © 2020, China Mechanical Engineering Magazine Office. All right reserved.
