Method for optimizing track of complex revolved body and system

Abstract

The invention discloses a method for optimizing a track of a complex revolved body and a system capable of realizing the method. According to the method, an initial track is generated according to a component laying angle and a material curvature requirement, then an offset track is generated by adopting equidistant offset, and the track is optimized by adopting an automatic fiber laying path optimization method adopting local adjustment and global optimization. According to the method, the variable curvature algorithm is fully utilized to generate the initial trajectory, the advantage of highefficiency of the equidistant bias algorithm is fully utilized on the basis of considering the structural design requirement and the fiber placement manufacturability requirement, the bottleneck thatthe manufacturability of the complex revolving body fiber placement trajectory is difficult to meet the design requirement is broken through, therefore, high-performance, high-efficiency and high-precision laying forming of the complex revolved body continuous fiber reinforced composite material can be achieved. Based on the optimized track, the manufacturability requirement and the structural requirement are met, and the comprehensive mechanical property of the component can be remarkably improved.
