建立了磁流变液测试系统的分数阶模型并进行了模拟,在自制的流变仪上针对不同的磁流变液进行了正弦波电流加载验。结果表明:分数阶模型下的计算数据能够较好地拟合试验数据,且磁流变液的粘弹性可由模型参数获得;分数阶系统模型可以从系统角度观察磁流变液的阻尼特性。
The fractional-order model for testing system of magnetorheological fluid was built up and used to make simulation, a self-made rheometer was used for loading sine wave currents on different magnetorheologieal fluids. The results show that the computational data in the fractional-order model could fit the experimental data well, and the viscoelasticity of magnetorheological fluid could be got from the model parameters and the fractional- order system model could describe the damping characteristics of magnetorheological fluid from systematic viewpoint.
