【摘要】：合理确定油槽的结构参数能有效地改善摩擦副间流体的流场特性和油膜剪切摩擦转矩性能。为了揭示摩擦副油槽结构对油膜剪切转矩的影响,以双圆弧油槽为研究对象,建立了集油槽结构参数化设计、流场数值模拟与试验设计方法(DOE)为一体的油槽结构参数影响分析平台。重点分析了液黏离合器摩擦副双圆弧油槽宽度、油槽对数、偏心距与内圈偏心圆直径对油膜剪切转矩的影响,并探究了各个参数的敏感性。结果表明,液黏离合器油膜剪切转矩随着摩擦副油槽宽度、油槽对数及内圈偏心圆直径的增大而增大,随着偏心距的增大而减小。摩擦副油槽宽度与内圈偏心圆直径是影响液黏离合器油膜剪切转矩的敏感参数。
[Abstract]:Reasonably determining the structural parameters of the oil tank can effectively improve the flow field characteristics of the fluid between the friction pairs and the friction torque performance of the oil film shear. In order to reveal the influence of the oil groove structure on the oil film shearing torque, the parametric design of the oil tank structure was established, taking the double circular arc oil groove as the research object. Flow field numerical simulation and experimental design method (DOE) as one of the oil tank structural parameters analysis platform. The effects of the width of double arc oil groove logarithm of oil groove eccentricity and diameter of eccentric circle of inner ring on the oil film shearing torque are analyzed and the sensitivity of each parameter is discussed. The results show that the oil film shearing torque increases with the increase of the width of the oil groove the logarithm of the oil groove and the diameter of the eccentric circle of the inner ring and decreases with the increase of the eccentricity. The width of the oil groove and the diameter of the eccentric circle of the inner ring are the sensitive parameters affecting the oil film shear torque of the fluid adhesion clutch.
