摘要
Fluent作为计算流体动力学(CFD)常用的商用软件,它可以对包含有流体流动和热传导等相关物理现象的系统做出分析,特别适用于极其复杂问题的流场.文中首先根据所设计的减振器建立数学模型,求出阻尼力的计算公式,接着采用GAMBIT软件建立减振器模型,并在Fluent中导入该模型,设置相关的参数及边界条件对该减振器进行数值分析.然后对结果进行分析,进而与理论模型的结果进行比较,最后对该减振器的性能进行了总结,并对其结构提出了几点建议.
Fluent as computational fluid dynamics(CFD) commonly used for commercial software,it can analyse the physical phenomena system which contains fluid flow and heat transfer,especially suitable for extremely complex problems flow field.In this paper,first of all,sets up the mathematical model by the desired damper,founds the formula about damping force,then builts the model of MR damper in GAMBIT,sets up relevant parameters and boundary conditions in Fluent,and analyses it.Finally,compares this results to theoretical,summarizes the performance of its structure,and puts forward some Suggestions.
