摘 要: | 磁路结构设计的优劣决定了磁流变(MR)阻尼器的性能品质。应用ANSYS的参数化编程语言(APDL)对MR阻尼器的磁路结构进行参数化建模。通过设置磁路结构各尺寸为设计变量、以模型中最大磁感应强度值为约束条件、以阻尼通道间的最大磁感应强度值为目标函数,进行优化分析。分析结果表明:优化后的磁路结构在阻尼通道处的磁感应强度提高了0.32倍,且分布更加均匀;优化后磁路结构的体积减小了7%,使磁路结构更加紧凑。说明APDL优化分析是一种设计磁路结构的切实高效的方法。

Optimization Design of the Magnetic Circuit Structure for Magnetorheological Damper Based on APDL |

Abstract: | The design of magnetic circuit structure determines the performance of magnetorheological ( MR) damper. The mag-netic circuit structure of MR damper was modelled by using ANSYS parametric programming language ( APDL) . By setting its structure size as design variable, the maximum magnetic flux density in the model as constraint condition, and the maximum magnetic flux densi-ty of the damping channel as objective function, the optimization analysis was carried out. The analysis results show that the magnetic flux density of the optimized structure in the damping channel is enhanced to 0. 32 times, and the distribution is more uniform. After optimizated, the volume of the magnetic structure is reduced by 7%, which makes the magnetic circuit structure more compact. So the APDL optimization analysis is an effective method for designing magnetic circuit structure. |
