【摘要】：針對(duì)永磁調(diào)速器(permanent magnet device,PMD)在三維磁場(chǎng)的仿真計(jì)算忽略了導(dǎo)體盤(pán)渦流生熱對(duì)性能的影響,提出一種基于電磁-熱耦合的有限元分析方法。利用Ansoft Maxwell和Ansys Workbench軟件搭建永磁調(diào)速器的電磁場(chǎng)和溫度場(chǎng)耦合仿真模型,分析渦流生熱對(duì)導(dǎo)體盤(pán)及永磁體性能參數(shù)的影響,將渦流熱功率作為熱源載荷導(dǎo)入溫度場(chǎng),并在Transient Thermal模塊中進(jìn)行溫度場(chǎng)仿真,將溫度場(chǎng)仿真結(jié)果用于修正永磁調(diào)速器的性能參數(shù),最終通過(guò)磁場(chǎng)仿真計(jì)算輸出轉(zhuǎn)矩。仿真結(jié)果表明:基于電磁-熱耦合計(jì)算的轉(zhuǎn)矩結(jié)果較改進(jìn)前相比與實(shí)測(cè)值誤差更小,適用于工程計(jì)算。
[Abstract]:A finite element analysis method based on electromagnetic-thermal coupling is proposed for permanent magnet governor permanent magnet device (PMD), in which the effect of eddy current heat generation on the performance of the conductor disk is neglected in the simulation of the three-dimensional magnetic field. The coupling simulation model of electromagnetic field and temperature field of permanent magnet governor is built by using Ansoft Maxwell and Ansys Workbench software. The influence of eddy current heat generation on the performance parameters of conductor disk and permanent magnet is analyzed. The eddy current heat power is introduced into the temperature field as a heat source load. The temperature field is simulated in the Transient Thermal module. The temperature field simulation results are used to modify the performance parameters of the permanent magnet governor. Finally, the output torque is calculated by magnetic field simulation. The simulation results show that the torque results based on electromagnetic and thermal coupling are smaller than those measured before, and are suitable for engineering calculation.
