Abstract A novel pressure-resistant oil-immersed proportional actuator, with a magnetic grid magnetic-isolated ring on its single-piece sleeve to replace the traditional nonmagnetic material magnetic-isolated ring, was designed to simplify manufacture process and minimize manufacturing costs. Magnetic simulation and experimental study were applied for both magnetic grid magnetic-isolated ring and nonmagnetic material magnetic-isolated ring proportional actuators. The results fit each other well and prove that, the working areas are 2.4 mm and 2.2 mm respectively, the maximum force outputs are 22 N and 15 N respectively, and they both have similar force output response characteristics. Hence, comparing to the traditional actuator, the novel proportional actuator has similar and good static and dynamic characteristics, and its applications to electro-hydraulic proportional valve are acceptable．

新型耐压湿式比例电磁铁的研制与对比试验研究
为了简化加工工艺、减少制造成本,提出一种基于一体式导磁套的新型耐压湿式比例电磁铁结构,采用磁栅隔磁环结构代替传统的非导磁材料隔磁环结构.对此新型电磁铁和传统的非导磁材料隔磁环电磁铁分别进行磁场仿真和试验研究,结果表明：在静态试验中,两者的工作区域分别为2.4 mm和2.2 mm,且其最大力输出分别为22 N和15 N；在动态试验中,两者具有相似的动态力输出响应特性.与传统隔磁环比例电磁铁相比,该新型比例电磁铁具有近似的静动态性能,可以广泛应用于电液比例控制阀.
