Abstract

This paper describes the design and construction of a prosthetic knee external four-bar mechanism for pelvic limb amputations to transfemoral level . Making process from design and calculations of the software taking biomechanical parameters of a healthy knee ; verifying and comparing the curves obtained with existing jobs. The mechanism was established to support the weight of a person to range between one hundred kilograms , using a finite element analysis it was possible to obtain a safety factor in the prosthesis that will provide peace of mind to the user on a fracture of the device. The construction of the device was using three materials: 6063 aluminum, 304 stainless steel and bronze, making the weight of the prosthesis is not exceeded and make it at the level of the most commercial. Based on the above, there has developed a prosthesis that mimics the motion of the knee, with great stability and at the same time it has a low cost. The device is intended to be incorporated into a modular prosthesis pelvic limb and work in an optimal control mechanism to regulate the acceleration walk.

带有四杆连杆机构的外膝关节假体

本文介绍了一种用于骨盆肢体截肢至经股水平的假膝外置四杆机构的设计和构造。采用健康膝关节的生物力学参数对软件进行设计和计算;将得到的曲线与现有作业进行验证和比较。该机构的建立是为了支持一个人的体重在100公斤之间，使用有限元分析可以获得假体的安全系数，这将为用户在设备骨折时提供安心。该装置的结构采用了6063铝、304不锈钢和青铜三种材料，使得假体的重量不超过，使其处于最商业化的水平。在此基础上，开发出一种模拟膝关节运动的假体，稳定性好，同时成本低。该装置将被整合到一个模块化的骨盆假肢中，并在一个最佳控制机制中工作，以调节加速行走。
