摘要
针对现有假肢接受腔大多依赖于人工手法取型的现状,提出了利用受力仿真软件生成接受腔模型并通过增材制造技术直接制造接受腔的智能制造方案。为避免残肢界面应力集中导致皮肤破损,设计了一种仿真取型法,通过对残肢压力耐受部位加压修型,得到残肢接受腔之间均匀受力的全接触小腿假肢接受腔,并通过仿真试验验证了该方法的可行性。
Currently,prosthetic receiving cavities mostly rely on the artificial mode.In this article,the intelligent manufacturing scheme which adopts the force simulation software to set up the model of receiving cavity and directly manufactures receiving cavities by means of the additive manufacturing technology is proposed.In order to avoid skin damage caused by stress concentration at the residual limb interface,a simulation method is developed to obtain the full-contact calf prosthesis receiving cavity with uniform force between the residual limb’s receiving cavities,by a series of pressure and shape operations on the pressure-resistant sections of the residual limb.Finally,the simulation experiment proves that the method is feasible.
