| 摘 要： | 磁流变液在零场时,符合牛顿流体的力学特征,在ANSYS中可用流体单元FLUID142模拟.而处于磁场作用下的磁流变液还呈现出一定的类固体特征,在ANSYS中尚无完全合适的单元进行模拟.本文提出一种在ANSYS中模拟磁流变液在屈服前阶段力学行为的方法,即重合单元法,主要思想是采用重合的两种单元分别模拟磁流变液的流体特性和...

| Abstract: | The magnetorheological fluid(MRF) is consistent with the mechanical properties of Newtonian fluid when no external magnetic field is present,at this time it can be modeled using FLUID142 in ANSYS.However,when exposed to a magnetic field,the MRF is also showing some solid-like characteristics,at present,there is no exactly appropriate element type in ANSYS to model MRF.This paper presents a method to simulate the mechanical behavior of magnetorheological fluid subjected to magnetic field in the pre-yield reg... |
