摘要
本文以汽车减振器工作状态为基础原型 ,用高级有限元分析软件ANSYS建立了双节流孔闭式油路稳态模型 ,分析了不同阀振速度下减振器模型内部流场、压力场、剪应力场分布的变化规律 ,为复杂闭式油路边界形状设计提供理论依据 ;同时也分析计算了此模型中节流孔壁剪应力与减振速度的函数关系以及壁压力与节流孔长度的关系 。
In this paper,a closed dual section fluid orifice oil flow steady model has been developed by FEM analysis software of ANSYS system,in which,the prototype is the automotive shock absorber.The purpose of the research is to analyze continuously variable rule of the fluid field,the pressure field and the wall shear stress field distribution in shock absorber model.The result indicated that,the pressure distribution at the compression phase (positive damper velocity)and rebound phase(negative damper velocity)are extremely similar which provided theoretic foundation for closed oil flow boundary shape design,and simultaneously calculated section flow orifice relationships between wall shear stresses and velocities,wall pressures and orifice length.
