A study on the development of the high thrust force linear valve actuator with multi-pole

首先，使用磁场的有限元分析来分析操作常规比例阀的比例螺线管的特性。结果，很明显，磁路中的三角形形式使得线圈电流与螺线管的推力之间成比例关系。在额定电流为1A时，该比例电磁铁可获得120N的推力。其次，利用PC机、AD和DA转换器，研制了一套传统比例电磁铁和新型比例电磁铁磁特性的自动测试系统。利用该测量系统对比例电磁阀的特性进行了测量，测量值与分析值基本一致。因此，本研究中与比例电磁铁及量测系统相关之有限元素分析，可供验证。 ...更多信息 设计了4个矩形凸极的耳驱动器。并对该驱动器进行了制作和测试。同时对所设计的驱动器进行了磁场分析。结果表明，作动器推力实测值与理论分析值吻合较好。结果表明，在额定电流下，样机的驱动力约为传统比例电磁铁的3倍。最后，设计了一种新结构的驱动器，并尝试扩大驱动器的工作范围。此外，通过改变磁极的形状，齿之间的间隔小得多，和驱动器的长度最小化。对新设计的作动器进行了推力特性测试。因此，致动器的工作范围大约是第一个原型的两倍。此外，很明显，该致动器的长度比市场上类似的电磁阀短，而市场上类似的电磁阀的推力和到阀体的安装面积相同。少

First, characteristics of a proportional solenoid which operates conventional proportion valve was analyzed by using Finite Element Analysis of magnetic field. As a result, it became clear that a triangular form in the magnetic path made proportional relation between coil current and the thrust of the solenoid. And, this proportional solenoid on the market was obtained the thrust about 120N when the coil rated current was 1A.Next, a automatically measuring system of magnetic characteristics of a conventional proportion solenoid and a new actuator was made by using personal computer, AD and DA converters. And then, characteristics of the proportion solenoid was measured by this measuring system, this measuring value agreed with the above mentioned analysis value. Therefore, the Finite Element Analysis related to the proportional solenoid and this measuring system in this study could be verified.After that, for obtaining design data of high thrust linear valve actuator, a cylindrical lin … More ear actuator with 4 numbers rectangular convex pole was designed. And this actuator was made and tested. At the same time, magnetic field analysis of the designed actuator was done. As a result, measured value of the actuator thrust agreed well with analysis one. And, it became clear that the force of the prototype actuator was approximately three times more than that of the conventional proportion solenoid at the rated current.Finally, a new structural actuator was designed and it was attempted that the working range of the actuator was enlarged. Furthermore, the interval between the teeth was much smaller by changing the magnetic pole shape, and the actuator length was minimized. The thrust characteristics of the newly designed actuator were measured. As a result, the working range of the actuator was approximately two times more than that of the first prototype. Also, it became clear that the length of this actuator was shorter than that of a comparable solenoid on the market whose thrust and installation area to the valve body are the same. Less
