| 摘 要： | 以传统叶片式减振器为基础,设计了具有"失效安全"特性的新型叶片式磁流变减振器。首先基于平板模型和B ingham模型推导了磁流变减振器力矩数学模型,然后分析了初始阻尼力不变情况下的阻尼力可调倍数影响因素,最后应用有限元分析软件ANSOFT对所设计的磁路进行仿真,分析了磁场分布。理论分析及仿真结果表明,叶片式磁流变减振器的阻尼力可调范围能满足重型车辆半主动悬挂系统的需要。

| Abstract: | Based on conventional vane hydraulic damper,a new vane MRF damper with fail-safe capability is designed.Firstly,the mathematical model of damping moment is deduced based on the parallel-plate model and Bingham model of MR fluids.Secondly,by analyzing some influencing factors of damping adjustable multiple,some ways are presented to augment the damping adjustable multiple under the condition of keeping initial damping moment invariable.Finally,the magnetic circuit is designed and magnetic field distribution ... |
