摘要
电磁激振器作为科里奥利质量流量计(CMF)的关键部件之一,其性能影响CMF测量精度。为了提高科氏质量流量计的测量精度,对电磁激振器进行了优化设计。首先,通过理论分析建立了电磁激振器的数学模型。然后,通过Solidworks建立了电磁激振器的三维模型,并结合COMSOL Multiphysics仿真软件参数化分析了磁铁、磁轭、工作气隙和线圈匝数对激振器电磁力的影响。基于参数分析,优化设计了电磁激振器的结构尺寸,使优化后的激振器能够保持较低的能耗。最后,将实验与仿真结果对比进行验证。结果表明:仿真与实验趋势具有较好的一致性,且仿真与实验所得电磁激振器在不同电流下平均效率的相对偏差均在±2.47%内,证明了所设计的电磁激振器结构的合理性,满足所设计科氏质量流量计的要求。该研究通过数值模拟方法及实验,对电磁激振器进行了优化设计和验证,节省了设计时间和试错成本,为设计适用于其他口径科氏质量流量计的电磁激振器提供参考。
As one of the key components of Coriolis mass flowmeter,the performance of electromagnetic actuator is closely related to the measurement accuracy.In order to improve the measuring accuracy of Coriolis mass flowmeter,the electromagnetic actuator was optimized.Firstly,the mathematical model of electromagnetic actuator was established through theoretical analysis.Then,the three-dimensional model of the electromagnetic actuator was established by Solidworks,and the effects of magnet,yoke,working air gap and coil turns on the electromagnetic force of the actuator were parameterized by COMSOL Multiphysics simulation software.Based on the parameter analysis,the structure size of the electromagnetic actuator was optimized,so that the optimized actuator can keep low energy consumption.Finally,the experimental results were compared with the simulation results to verify.The results show that there is a good agreement between the simulation and the experiment trend,and the relative deviation of the average efficiency of the actuator under different current is within±2.47%,which proves the rationality of the designed actuator structure and meets the requirements of the designed Coriolis mass flowmeter.Through numerical simulation method and experimental means,the electromagnetic actuator is optimized and verified,which saves the design time and trial and error cost,and provides reference for designing the electromagnetic actuator suitable for other calibers Coriolis mass flowmeters.
