Abstract

The invention relates to a MATLAB-based suit cutting and splicing calculation method for silicon steel sheets, and belongs to the technical field of design and manufacturing of transformers. According to the technical solution, the method comprises the steps of introducing a matrix thought to substitute application of loop statements in a basic language, and compiling a splicing algorithm based on an exhaustive method program to program artificial splicing experience, thus improving the utilization rate of a raw material; compiling a condition algorithm in combination with artificial calculation experience, and performing logic calculation to reduce the exhaustive range and the cycle index; comparing the merits of artificial calculation and program calculation, and formulating a calibration method. The method has the advantages of substituting artificial calculation, reducing the workload of staffs, ensuring the calculation accuracy and reducing personal errors; compared with a cyclic algorithm, the matrix-based calculation method remarkably improves the calculation speed and improves the calculation efficiency; and the purpose of material saving calculation is not necessarily to calculate the optimal solution, but to improve the calculation speed as much as possible while ensuring the utilization rate, thereby ensuring the working efficiency.

Description

technical field [0001] The invention relates to a MATLAB-based calculation method for cutting and piecing together silicon steel sheet sleeves, and belongs to the technical field of transformer design and manufacture. Background technique [0002] Large-scale power transformer cores are made of silicon steel sheets. It is necessary to cut the silicon steel sheets from the raw materials into finished products for stacking. Two methods are generally used to improve the utilization rate of the raw materials. Method 1: Combination cutting of the original required size, this method is to cut the original packaging material into strips according to the required width, and seek the least waste combination method. Method 2: Changing the original size into pieces, that is, under the premise of ensuring the product performance, change the required size with a larger original width into two smaller width sizes to splicing and stacking, so as to improve the overall utilization rate of t...
