建立了三相交流电动机一弹性连杆机构系统的耦合动态方程,用多尺度法分析了该系统在电磁力作用下的主共振现象,得到了该系统的主共振特性与电磁力之间的内在联系。最后通过实验证明了理论分析结论与实验结果相符。
The coupling dynamic nonlinear equations for a three-phase AC motor and elastic linkage mechanism system were derived, and primary resonance effected by electromagnetic force was analyzed by using the multi-measure method. The internal relationship between primary resonance and electromagnetic force was obtained. An experiment shows that theoretical analysis results are consistent with the experimental results.
