近年来,随着磁流变液智能材料的研制成功,磁流变液减振器以其响应快、易实现计算机控制等优点得到普遍的关注。磁流变液智能材料在车辆减振与隔振、流体传动与控制的应用日益广泛。运用UG软件对磁流变液减振器进行三维建模;通过Parasolid将减振器模型导入ADAMS软件中,运用多刚体动力学分析软件建立四分之一汽车悬架模型,并分别在无控制阻尼、有控制阻尼的条件下进行仿真试验。仿真试验结果表明,有控制阻尼时车身位移达到稳定所需的时间较小、振动稳定后加速度峰值较大、车身位移的幅值较小,隔振效果明显。
In recent years, with the successful development of magnetorheological fluid intelligent materials, magnetorheological fluid shock absorber has received widespread attention due to its fast response and easy realization of computer control. Magnetorheological fluid intelligent materials in the vehicle vibration and vibration isolation, fluid transmission and control of the increasingly widespread application. UG software was used to make 3D modeling of MR fluid damper. The damper model was imported into ADAMS software by Parasolid. One-quarter automobile suspension model was established by multi-body dynamics analysis software. Damping, with controlled damping under the conditions of simulation test. The simulation results show that the time required for the vehicle body to reach a stable position when the control is damped is small, the acceleration peak is large after the vibration is stabilized, and the amplitude of the displacement of the vehicle body is small, and the vibration isolation effect is obvious.
