摘要

为研究磁流变液在不同磁场作用下的挤压与拉伸力学性能

建立了用于测试磁流变液挤压与拉伸特性的实验装置

并通过ANSYS/Multiphysics对此实验装置磁路的磁感应强度分布进行了仿真分析。利用此装置研究了磁流变液在不同外加磁场强度下的挤压和拉伸特性

并建立了拉伸屈服应力与剪切屈服应力之间的关系。挤压实验表明

磁流变液在挤压应变约为0.15时具有最小的压缩弹性模量;当挤压应变大于0.15时

挤压应力和挤压弹性模量与挤压应变表现为指数关系

且指数随着外加磁场的增大呈上升趋势。拉伸屈服应力约为剪切屈服应力的4倍

据此计算得到的剪切屈服应变角在13.8~16.9

验证了物理模型对磁流变液剪切应力描述的合理性。

Abstract

The compressive and tensive characteristics of Magnetorheological(MR) fluid were investigated with a magnetic field. A experiment setup was designed and fabricated to test the compressive and tensive properties and the magnetic behavior of the equipment was analysed by using the ANSYS/Multiphysics. The compressive and tensive resistance of the MR fluid was then measured for different field strengths

and the relation between tensile yield stress and shear yield stress for the same magnetic field was developed. The compressing tests show that the MR fluid has a smaller compressive modulus when a compressive strain is about 0.15. The compressive stress and compressive modulus have an exponential relationship with the compressive strain when they are higher than 0.15.Moreover

the exponent increases with the enhancement of the applied magnetic field. The tensile yield stress is about four times of shear yield stress. According to the results above

The shear yield angle is calculated to be 13.8-16.9. Obtained results prove the retionability of the physical model for describing the shere stress of MR fluid.
