Abstract

The invention discloses a prefabricated body texture pattern generation method and a device, electronic equipment and a storage medium. The method comprises the steps of acquiring initial structure information of the prefabricated body to be prepared; generating an initial texture drawing of the to-be-prepared prefabricated body according to the initial structure information; wherein the pixel values of the pixel points in the initial texture pattern comprise a first pixel value and a second pixel value, when the warp yarns corresponding to the pixel points are above the corresponding weft yarns, the pixel values of the pixel points are the first pixel value, and when the warp yarns corresponding to the pixel points are below the corresponding weft yarns, the pixel values of the pixel points are the second pixel value; obtaining yarn reduction information of a to-be-prepared prefabricated body; wherein the yarn reduction information comprises the actual warp layer number and the yarn reduction position information at the interweaving point of each column of warp and each column of weft in the to-be-prepared prefabricated body; and adjusting the initial texture drawing according tothe yarn reduction information to obtain a texture drawing of the to-be-prepared prefabricated body. By implementing the method, the texture pattern of the to-be-prepared prefabricated body can be automatically generated with relatively high efficiency and relatively high accuracy.

Description

technical field [0001] The invention relates to the field of manufacturing technology, in particular to a method, a device, an electronic device and a storage medium for generating a texture pattern of a preform. Background technology [0002] Three dimensional woven structure composites are more and more popular because of their high specific strength, low density and good formability. They have been successfully used in aircraft and automotive engineering. At present, for large variable thickness preforms with complex structure and surface, net forming manufacturing is usually realized by increasing or decreasing yarn based on electronic jacquard system. However, due to the large number of yarn reduction points in the variable thickness preform with complex structure and shape surface, there is no certain law in the yarn reduction position and the number of yarn reduction layers. For example, the number of yarn reduction points of aeroengine fan blade is up to thousands of poin...
