摘　　要：血液在高转速下可能出现溶血的现象,利用章动原理设计了一款新型的心室辅助泵,有效地降低了设计转速。首先对微型章动心室辅助泵进行三维建模,之后对泵体内部流场开展实时仿真,获得心室辅助泵内部的流动特性,最后对微型章动心室辅助泵进行实物加工,开展水介质的性能实验,验证了微型心室辅助泵的可行性。Due to the hemolysis of blood at high rotational speed,a new type of ventricular assist pump is designed based on the nutation principle.It can be used to greatly reduce the design speed.3D modeling of the miniature nutation ventricular assist pump is implemented firstly,then,the dynamic real-time simulation of flow field inside the pump body is done,in order to obtain the flow characteristics.And then,this assist pump is made and the water-medium experiment is conducted to verify its feasibility.
