中文摘要:针对现有的位置直接反馈式二维(2D)伺服阀的液压伺服螺旋结构复杂和加工昂贵的不足,提出一种具有反馈机能的浆翼式力矩马达,将其作为电—机械转换接口与阀芯相连而构成结构简单、加工成本低的力反馈式二维(2D)伺服阀。加工了3种不同浆翼倾角的马达样机并搭建了实验台架,分别采用磁路解析、有限元模拟和实验研究的方法研究了该马达的反馈力矩与衔铁轴向位移之间的特性关系。实验结果和模拟结果基本相符,显示该马达的反馈力矩—位移特性曲线呈线性关系,且幅值随着衔铁位移增加而增大;对比不同倾角的特性曲线可以得知,增大浆翼倾角是增加反馈力矩的有效手段。

Abstract:Hydraulic valves were designed with two dimensional (2D) concept uniquely integrated pilot stage and power stage into single spool by taking advantage of both translational and rotary degrees of freedom. It was featured with simple structure, excellent anti-pollution capability, high ratio of power to weight and fast dynamic response, which attracted considerable attention in several areas of modern industry. In order to solve the problem that hydraulic servo screw of direct position feedback 2D servo valve had deficiency of complicated structure and high manufacturing cost,a novel paddle wing torque motor with feedback function was proposed. The motor could be used as electro mechanical converter and directly connected with spool to constitute a novel force feedback 2D servo valve with simple structure and low manufacturing cost, which was suitable for civil servo valve application. Three types of prototype motors with different inclined angles of paddle wing were manufactured and the test rig was built. The relationships between feedback torque and armature displacement were studied by using methods of magnetic circuit analysis, FEM simulation and experiments. The experimental results were agreed with the simulated results. It was indicated the characteristics between feedback torque and armature displacement were close to linear relationship and its amplitude was raised with the increase of displacement, whose magnitudes reached about 0.098N·m, 0.132N·m and 0.16N·m with paddle wing’s inclined angles of 9°, 12°and 15°, respectively. It was proved that increasing inclined angle was an effective approach to increase feedback torque.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
