基于有限元方法的磁流变阻尼器多目标优化设计
|
摘要
在分析了影响磁流变阻尼器阻尼性能的参数基础上,建立了磁流变阻尼器的多目标结构优化设计数学模型。结合磁场与结构耦合分析,利用一阶优化有限元法对其进行了优化计算,优化达到了预期的效果,为磁流变阻尼器多目标结构优化设计提供了参考依据。
On the basis of analysis about performance of magetorheological damper,the multi-optimal mathematical model of MR damper is built up. Combining magnetism-structure coupling analysis and FEM of first-order optimization,the structural parameters of MR damper are optimized,and the results realize the predicted purpose and provide theoretical reference for multi-objective optimal design of MR damper.
