中文摘要:
      为了研究人工心脏经皮无线供能系统各电路电量与物理场场量之间的相互关系以及系统生物安全性,提出了一种多物理场仿真研究方法。该方法基于COMSOL仿真软件建立了经皮无线供能系统的电-磁-热多物理场耦合模型,模型包括电路模型和几何模型,电路模型主要包括逆变电路、补偿电路和整流滤波电路,几何模型主要包括发射线圈、接收线圈以及人体皮肤生物组织模型。通过仿真计算获得经皮无线供能系统在谐振和非谐振状态下各电路的电流、电压波形以及生物组织安全性指标比吸收率、场强和温度的数值,并参照国际人体电磁安全和人体生理学标准进行安全性评估,该研究为人工心脏经皮无线供能系统的设计和优化提供了有力的分析工具。
英文摘要:
      In order to analyze the relationship between the circuit current, voltage and physical field quantities in the transcutaneous wireless power supply system of artificial heart, a Multiphysics simulation method is proposed in this paper. An electro-magnetic-thermal Multiphysics coupling model is established for the transcutaneous wireless power supply system based on COMSOL simulation software. The model includes both circuit model and geometric model. The circuit model mainly includes inverter circuit, compensation circuit and rectification and filtering circuit, the geometric model mainly comprises a transmitting coil, a receiving coil and a human skin biological tissue model. The current, voltage waveform and biological safety indexes of absorption rate, field strength and temperature values of the transcutaneous wireless power supply system in resonant and non-resonant states can be obtained by means of simulation. The biosafety assessment can be carried by comparing these indexes with reference values of the international human electromagnetic safety and human physiology standards. The simulation results verify the biosafety of the transcutaneous wireless power supply system. This method provides a powerful analysis tool for the design and optimization of the artificial heart transcutaneous wireless power supply system.
