摘要
以汽车空调吹脚风门为研究对象,首先通过对空调系统CFD的仿真分析,得到吹脚风门的速度矢量图、静压图和温度分布图,为吹脚风门的改进设计提供依据。然后,对吹脚风门的导流面、控制风门开度的机构以及连动机构进行改进设计,并对改进后的结构进行刚度校核。结果表明,在满足刚度要求的情况下,吹脚风门质量明显减轻。最后通过风门扭矩试验得到原始吹脚风门和改进后吹脚风门的负载扭矩曲线,将二者进行比较分析,从而验证改进方案的有效性和准确性。
Taking the automotive air conditioning blowing foot throttle as the goal, the blowing foot throttle of velocity vector, static pressure and temperature distribution diagram are obtained through the air conditioning system of CFD simulation analysis ,which provide a basis for improved design. And then, guide surface, control mechanisms and transmission mechanisms of the blow foot throttle are improved design, and stiffness analysis is finished for the improved structural. The results show that, the weight de- creased obviously under meeting the requirements of stiffness. Finally, load torque curves are obtained by throttle torque test of the original blow foot throttle and improved throttle blowing foot,which verify the validity and accuracy improvement program accord- ing to the comparison and analysis.
