    摘要:

    以提高磁粉離合器轉(zhuǎn)矩容量為目的，在深入研究其工作機(jī)理的基礎(chǔ)上，利用虛位移電磁力計(jì)算理論推導(dǎo)得出了轉(zhuǎn)矩傳遞公式；以麥克斯韋方程為磁場(chǎng)分析的理論基礎(chǔ)，建立了磁粉離合器二維有限元分析模型并進(jìn)行了計(jì)算，仿真結(jié)果與試驗(yàn)結(jié)果吻合；根據(jù)仿真分析結(jié)果，對(duì)其進(jìn)行了改進(jìn)設(shè)計(jì)，改進(jìn)后的磁粉離合器轉(zhuǎn)矩性能提高了45%。

    Abstract:

    To increase the torque capacity, the torque-transferring formula was deduced from electromagnetic force theory of virtual displacement according to working mechanism of magnetic particle clutch. The FEM model was established based on theory of Maxwell equation for analysis magnetic field and its simulation results conformed to the test results. According to the simulation results, improved design was made on magnetic particle clutch. The results showed that the improved magnetic particle clutch had a remarkable effect on the torque performance, and its torque performance increased by 45%.
