摘　　要：针对在电磁制动与摩擦制动并用的集成制动系统的设计与控制中,确定制动盘磁感应强度存在计算工作量和误差大的问题,根据位势能理论和Maxwell方程,建立了电磁制动器中制动盘某点处的磁感应强度的预测模型。基于此模型,对某一电磁制动器的制动盘在不同磁极长度、磁极宽度和磁极面与制动盘间距下的磁感应强度进行预测。结果表明:当磁极长度为120mm,磁极宽度为40mm,磁极面与制动盘间距为1mm时,磁感应强度达到最大,与传统的理论计算结果基本吻合。In view of the problems in designing and controlling integrated brake system combining electromagnetic brake and friction brake,i.e.the required significant computing efforts with large error in calculating magnetic induction intensity on brake disk,a model for estimating the magnetic induction intensity at certain point on the brake disk of electromagnetic brake is built based on potential theory and Maxwell equations.Based on the model,the magnetic induction intensity on the brake disk of an electromagnetic brake with different lengths and widths of magnetic pole and different gaps between magnetic pole and brake disk is estimated.The results show that the magnetic induction intensity reaches its maximum value with a 120mm length and 40mm width of magnetic pole and a 1mm gap between magnetic pole and brake disk,agreeing well with that of traditional theoretical calculation.
