Abstract

The invention relates to the technical field of medical instruments, in particular to a reverse optimization method for porous structure material design. According to the method, a series of mechanical property researches are carried out on a specific material and a specific porous structure in advance aiming at an irregular-shaped porous structure workpiece or a customized porous structure workpiece to obtain basic research data of mechanical properties under different wire diameters, and then uniform porous structure design is firstly carried out on the workpiece to be designed. The stress distribution condition of the workpiece in the corresponding stress environment is simulated in a finite element analysis mode, then the porous structure workpiece is correspondingly adjusted again, the wire diameter of the area with large stress is properly increased, the wire diameter of the area with small stress can be properly reduced, and therefore reverse optimization of the porous structure design is achieved.

Description

Technical field[0001]The present invention relates to the field of medical devices, in particular, to a reverse optimization method for a porous structural material design.Background technique[0002]The porous structure is currently widely used in aerospace, medical equipment, etc., by designing the workpiece to a porous structure, can minimize workpiece quality, in the field of medical equipment, in the field of medical equipment, and implant The porous structure can not only reduce the elastic modulus of the implant, reduce the stress shielding effect, but also provide an attachment and growth of bone cells, and achieve the bone growth effect, so that the implant is formed with human natural bone. Organic overall.[0003]The current porous structural design is often uniformly distributed. The researchers tend to optimize the multi-well structural workpiece based on porous structural or material properties, and the porous structural products designed in this way often encounter a bott...
