摘要： 先导溢流阀是阻尼连续可变减振器的关键部件,使减振器具有阻尼连续可调能力,而圆环型弹性阀片是影响先导溢流阀的开度、压力等参数的关键零件。为查明圆环型弹性阀片变形规律与先导溢流阀开度的映射机制,推导了圆环型弹性阀片变形的数学模型,在先导阀开度为0~0.25 mm,阀片厚度为0.1~0.3 mm的情况下进行计算分析,验证了变形模型的准确性,并揭示了先导溢流阀开阀压力、入口压力、溢流阀阀口内外压差和溢流阀开度的变化规律,获取了溢流阀开阀压力、压差、开度与圆环型弹性阀片厚度的关系曲线,为先导溢流阀的高精密设计及减振器阻尼匹配、优化提供理论指导。

Abstract: The pilot relief valve enabling the shock absorber to have continuous damping adjustability,is a crucial component of the continuously variable damping shock absorber. And the annular elastic valve plate is a key component that affecting the opening degree,pressure and other parameters of the pilot relief valve. To find out the deformation regularity of the annular elastic valve plate and its mechanism of mapping to the opening degree of the pilot relief valve,a mathematical model for the deformation of the annular elastic valve plate,which is conducted by calculating and analyzing under the conditions on the pilot valve opening degree′s range of 0~0.25 mm and the valve plate thickness range of 0.1~0.3 mm,was derived. The accuracy of the deformation model was verified,and the changing regularities of the valve opening pressure,inlet pressure,differential pressure for valve hole of pilot relief valve,and opening degree of relief valve were revealed. The curves of relief valve opening pressure,differential pressure,and opening degree versus the thickness of annular elastic valve plate were obtained.This provides theoretical guidance for the highly precise design of pilot relief valves and the matching and optimizing of shock absorbers′ damping.

Key words: pilot relief valve, annular elastic valve plate, characteristic of opening degree, computational fluid dynamics, shock absorber
