摘要
针对气浮悬挂装置运动过程中的气压波动和惯性力补偿问题,提出一种电磁力补偿装置,通过钕铁硼磁体产生磁场,设计了合理的磁路。应用Maxwell对该装置进行磁场仿真,通过对比及分析,优化了导磁材料的尺寸和结构,使有效行程内气隙中磁感应强度保持恒定,控制线圈回路中的电流产生需要的电磁力,补偿气压力与目标力的差值和惯性力。
Aiming at air pressure fluctuation and redundant inertia force caused by the motion of air floating suspension system, this article proposes a electromagnetic force compensation device. NdFeB magnet was used for designing a proper magnetic circuit to generate magnetic field. Maxwell was used for simulating and analyzing the magnetic circuit of this mechanism. By comparison and analysis, the structures and sizes of magnetic conductive material was optimized, which can keep the same value of magnetic induction in the air gap within the effective stroke. This system can compensate the force difference between air pressure and desired firce and inertia force by controlling the current flowing though the coils.
