摘要:
矫正鞋垫可通过3D打印技术定制,而支撑鞋垫的拓扑晶格结构可利用有限元分析来探索优化。基于面心立方(FCC)、体心立方(BCC)这2种常规晶格支撑结构建立结构模型,分析寻找最优拓扑结构,并深化构造FCC和BCC复合结构模型,研究结构因子及晶格轮廓对矫正支撑性能的影响。模拟结果显示,相同受力条件下,FCC晶格结构支撑强力较高,同等变形下的抗压力较大; 对于由FCC和BCC组成的复合结构,其有限元分析的参数值随着FCC结构在复合模型中所占比例的降低而增加,且FCC占比每减小25%,应力增大约1.03倍。模拟结果证明,FCC结构在支撑矫正鞋垫时具有理论和实用的一致性,能形成良好的足底压力分布。
Abstract:
3D printing technology can customize the orthotic insole, while the topological lattice structure supporting the insole can be explored for optimization using finite element analysis. A structural model was established based on two conventional lattice support structures, face-centered cubic(FCC)and body-centered cubic(BCC). This paper analyzed and searched for the optimal topology, deepened the construction of the composite structural model of FCC and BCC, and studied the effects of structural factors and lattice profiles on the corrective support performance. Simulation results show that under the same stress conditions, the FCC lattice structure has the higher support strength and the larger compressive force under the same deformation. For the composite structure composed of FCC and BCC, the values of the finite element analysis parameters increase with the decrease of the proportion of the FCC structure in the composite model, and the value of the stress increases by about 1.03 times for each 25% decrease of the FCC proportion. The simulation results prove that the FCC structure has theoretical and practical consistency in supporting the orthotic insole and can form a good plantar pressure distribution.
