[0032] In order to better illustrate the technical solution of the present invention, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0033] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and propose an improved continuum structure topology optimization post-processing method, which uses less grid division numbers, that is, the finite element analysis unit size is greater than the default value 1, When performing topology optimization on the target model, it can effectively avoid the fine columnar structure caused by too many grids; perform binarization on the optimized model, analyze the optimized model and extract the zigzag boundary line, and obtain the target discrete corner point set through numerical calculation , using it as a sample point for curve fitting, effectively avoiding a large deviation between the post...
