To design a porous titanium alloy structure suitable for cervical spine implants, according to different stress conditions of cervical spine, such as compression, compression-shear, compression-torsion, and compression-bending, four types of unit cell structures, TO-C, TO-CS, TO-CT, and TO-CB, were constructed by combining topology optimization and computer-aided design. The mechanical properties were analyzed by compression simulation. Finally, the quasi-static compression test of porous samples with porosity of 60% prepared by laser powder bed fusion technique was conducted. The results of finite element simulation and compression test show that the compressive properties and elastic moduli of the four porous structures meet the requirements of human bone implants. Among them, the TO-CB structure has the best compressive performance and is suitable for porous titanium alloy cervical spine implants.

为了设计适用于颈椎植入物的多孔钛合金结构，根据颈椎受压缩、压缩-剪切、压缩-扭转、压缩-弯曲等不同受力情况，利用拓扑优化和CAD相结合的方法构建出4种单胞结构TO-C、TO-CS、TO-CT、TO-CB，并通过压缩仿真进行力学性能分析；最后对采用激光粉末床熔融技术制备的孔隙率60%多孔试件进行了准静态压缩试验。有限元仿真和压缩试验结果共同表明，4种多孔结构的抗压性能和弹性模量均满足人体骨植入物的需求，其中，TO-CB结构的抗压性能最优，适用于作为多孔钛合金颈椎植入物。
