摘要

中文摘要: 为了准确获知车辆减振器内部温度分布状况，进而为其可靠性设计奠定基础，以某车辆减振器对称性结构特点为依据，建立了具有较高精度的节流阀系流体网格模型。应用计算流体动力学(CFD)数值方法并采用CFX仿真软件对其进行谐波激励下的模拟，仿真计算出工作缸管内强迫对流换热的传热过程，进而得出此减振器油液的热量产生过程和温度场分布情况。研究结果表明：应用此仿真方法，可明确车辆减振器的温升过程和生热机理，能为完善减振器温升理论的研究提供参考。

Abstract

Abstract:In order to accurately learn the interior temperature distribution condition of the vehicular shock absorber

and thus lay the foundation for its reliability design

a high accuracy fluid grid model which described the throttle valve was established on the basis of the symmetry structural characteristics of a vehicular shock absorber. By applying the computational fluid dynamics (CFD) numerical method and using the CFX simulation software

it was simulated under a harmonic excitation and the heat transfer process of forced convection in the working cylinder tube was calculated

furthermore the heat generation process and temperature field distribution situation of oil in the shock absorber was obtained. The study results show that by using this simulation method

the temperature rising process and heat generation mechanism of the vehicular shock absorber can be clarified

in addition some references which are used to improve the research on the temperature rising theory of the shock absorber

can be provided from the analysis conclusions.
