【摘要】：以大间隙磁力传动系统的电磁体为研究对象,研究了电磁体铁芯材料与结构参数对系统驱动能力的影响,确定了电磁体铁芯采用Z10-T25取向硅钢片可提高系统驱动能力;根据所建立的系统启动过程动力学模型,研究了实现轴流式血泵快速平稳启动的加速控制方法,并将实验数据与理论仿真解析结果进行了对比:在电磁线圈通电脉冲频率从0Hz到150Hz的启动过程中,血泵转速从0r/min加速到9 000r/min,血泵出口压力p和流量Q的实验值均与理论仿真值变化趋势一致。研究表明驱动系统可在4s以内使轴流式血泵的输出压力和流量达到控制目标值。
[Abstract]:Taking the electromagnet of the magnetic drive system with large gap as the research object, the influence of the core material and structure parameters of the electromagnet on the driving ability of the system is studied. It is determined that the driving ability of the system can be improved by adopting the Z10-T25 oriented silicon steel sheet in the electromagnet core. According to the dynamic model of the system start-up process, the acceleration control method to realize the fast and steady start of the axial flow blood pump is studied. The experimental data are compared with the theoretical simulation results: during the start-up of the electromagnetic coil from 0Hz to 150Hz, the speed of the blood pump accelerates from 0r/min to 9 000 r / min. The experimental values of blood pump outlet pressure p and flow Q are consistent with the theoretical simulation values. The results show that the output pressure and flow rate of the axial flow blood pump can reach the control target value within 4 s.
