在设计磁粉离合器时,根据运转动态下工作间隙中磁粉的磁化曲线(B_δ~H_δ关系曲线)建立电和磁的关系,根据运转动态下工作间隙中剪切力特性曲线(B_δ~τδ关系曲线)建立磁和力的关系,从而完整的建立起电-磁-力的关系。我所在80年完成磁粉静态磁性能的测试并用于设计,但静态磁粉的分布和运转动态下磁粉的分布情况很不相同。存在一定误差。有的单位也曾进行过运转动态下工作间隙中磁粉的B_(?)、H_δ和τδ值的研究,但H_δ值是计算出来的(我所也于1979年做出结果)试验数据反常,当磁场升高到一定限度时,随着磁场的增大,μ值反而升高,致使作出的磁化曲线结果(B_δ~H_δ关系曲线)作为磁粉离合器设计的依据是很不够的。
In the design of magnetic clutch, the relationship between electric and magnetic is established according to the magnetization curve (B_δ ~ H_δ curve) of the magnetic powder in the working clearance under the running dynamic state. According to the shear force characteristic curve (B_δ ~ τδ curve) The establishment of the relationship between magnetic and force, so as to establish the complete electric-magnetic-force relationship. My 80 years to complete the static magnetic properties of magnetic particle testing and used in the design, but the static magnetic powder distribution and dynamic distribution of magnetic powder is very different. There is a certain error. Some units have also carried out studies on the B _ (?), H_δ and τδ values of magnetic particles in the working clearance under running dynamics. However, the H_δ values are calculated (I also made the results in 1979). The experimental data are abnormal. As the magnetic field increases to a certain limit, the value of μ increases with the increase of the magnetic field. As a result, the result of the magnetization curve (B_δ ~ H_δ relation curve) is not sufficient as the basis for the design of the magnetic powder clutch.
