Modeling and Dynamic Simulation of Conical Blood Pump Virtualprototyping Based on Pro/E and Adams

介绍了运用Pro/E软件对磁悬浮锥形螺旋叶轮血泵的结构设计与建模,通过PRO/E与ADAMS两个软件之间的专用接口程序Mechanism/Pro生成刚体和定义简单约束后,把锥形螺旋叶轮血泵模型传递到机械系统动力学仿真分析软件ADAMS中,添加复杂约束和力,特别是为了模拟磁悬浮力的作用,将其简化为等效的弹簧力的作用,然后进行锥形螺旋叶轮血泵系统的运动学和动力学仿真分析,得到血泵系统不同运行时段的力、位移、速度和加速的曲线。仿真分析表明所设计的血泵理论上可以满足人工心脏要求的设计指标,研究方法为缩短血泵的设计开发周期提供了强有力的手段。

This paper introduces the structural design and modeling of conical blood pump by the use of Pro/E software, through the interface module Mechanism/Pro of Pro/E and ADAMS which defines rigid bodies and simple constraints, then the conical blood pump model is introduced into ADAMS in which complex constraints and forces are added, specially to simulate the role of magnetic levitation forces, the magnetic levitation forces are simplified and equivalent to the role of spring forces, following to kinematic and dynamic simulation analysis of conical blood pump,the force,displacement, velocity and acceleration curves of blood pump system are gained in different periods. Simulation analysis shows that the designed blood pump theoretically meets the specifications of artificial heart requirements.and the research method provides a powerful tool for shortening the design and the development of the cycle of blood pump.
