项目摘要

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

首先，利用磁场有限元分析方法分析了一种工作在常规比例阀上的比例电磁阀的特性。结果，很明显，磁路中的三角形使线圈电流与螺线管的推力成比例关系。市场上的这种比例电磁铁在线圈额定电流为1A时获得了约120N的推力。其次，利用PC机、AD和DA转换器组成了一种常规比例电磁铁和一种新型执行机构的磁特性自动测试系统。然后，利用该测量系统对比例电磁阀的特性进行了测量，测量值与上述分析值基本吻合。在此基础上，为获得大推力直线气门执行器的设计数据，设计了圆柱型直线气门…设计了4个矩形凸极的多耳执行器。并对该执行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，执行器推力的实测值与分析值吻合较好。在额定电流下，样机的作用力约为传统比例电磁铁的3倍。最后，设计了一种新的结构作动器，并尝试扩大了作动器的工作范围。此外，通过改变磁极形状使齿间距变得更小，并最小化了驱动器的长度。对新设计的执行器进行了推力特性测试。结果，该执行器的工作范围大约是第一个原型的两倍。此外，很明显，这种执行器的长度比市场上类似的螺线管的长度要短，后者的推力和阀体的安装面积相同。较少
