这个模型的力学特性可以通过使用有限元分析。数学模型可以被假定为肘关节。假设10 N力量应用于前臂手工作负载。肱骨30度不同的夹角150度看肘关节运动如以下图所示。根据这些数据做了一个模拟的新设计使用快速原型技术提高假体植入的肘关节。这是作为有限元分析。关节臂的有限元模型是描述在下面图。一些属性的材料用于肘关节设计和开发有皮质骨(杨氏模量= 17.3的绩点,泊松比= 0.3,密度= 1.9 x103公斤/立方米),人工关节(杨氏模量= 230 GPa,泊松比= 0.321,密度= 8.2 x103公斤/立方米),和韧带(杨氏模量= 0.1的绩点,泊松比= 0.49,密度= 1.0 x103公斤/ m3)。从分析可以得出结论,反应力会随着角度的增加,有肘关节的植入物的设计制造使用快速原型技术,因为相应的角度可以设置,妥善。
The mechanical characteristics of this model can be done using finite element analysis. The mathematical model can be assumed as for the elbow joint. Assume that 10 N forces are applied to the forearm hand as workload. The angle between the humerus varies from 30 degree to 150 degree to see the elbow joint movement as shown in below figure. Based on this data a simulation was done to see how the new design using rapid prototype technology enhances the prosthetic elbow joint for implant. This was done as Finite Element Analysis. The finite element model for joint and arm is described in below figure. Some of the properties of the material used for the elbow joint design and development are given as Cortical Bone (Young’s modulus =17.3 GPa, Poisson’s ratio = 0.3, Density = 1.9×103 Kg/m3), Artificial Joint (Young’s modulus =230 GPa, Poisson’s ratio = 0.321, Density = 8.2×103 Kg/m3), and Ligament (Young’s modulus =0.1 GPa, Poisson’s ratio = 0.49, Density = 1.0×103 Kg/m3). From the analysis it can be concluded that the reaction forces decreases as increase in angle, there the design of implant of elbow joint is manufactured using Rapid Prototype technology, because the angle can be set accordingly and properly.
