The present invention provides a method and device for planning a trajectory for laying fiber composite materials on a cylindrical surface, wherein the method for planning a trajectory for laying includes: S10 obtaining a corresponding flat surface based on the cylindrical surface on which the prepreg tow is to be laid, and Determine a NURBS curve of a prepreg tow laid in the plane rectangular coordinate system according to a preset rule, and the prepreg tow is prepared from fiber composite materials; S20 converts the NURBS curve laid in the plane rectangular coordinate system of the prepreg tow to Cylindrical coordinate system to obtain the laying curve of the prepreg tow on the cylindrical surface; S30, according to the laying curve of the prepreg tow on the cylindrical surface, rotate around the Z axis to sequentially determine the other prepreg tow on the cylindrical surface. Lay the curve to complete the planning of the laying trajectory of the prepreg tow on the cylindrical surface. It effectively solves the technical problems of the existing fiber composite material on the cylindrical surface, such as the complicated steps to obtain and the inability to guarantee the smoothness of the curve.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for laying track planning of a fiber composite material on a cylindrical surface. Background technique [0002] Fiber composite material is a material with 2-phase or more than 2-phase structure compounded by organic polymer matrix material and high-performance fiber-reinforced material through a special molding process. Fiber-reinforced composite material is light in weight, specific With the advantages of high quantity, no reflection of electromagnetic waves, and large degree of design freedom, it is more and more used in daily life and military fields. Due to the characteristics of stable quality and high molding efficiency (about 5 to 20 times the efficiency of manual laying), the automatic lay-up molding technology has been applied in foreign aircraft manufacturing enterprises. The use of fiber-reinforced composite materials can reduce the weight...
