摘要:
为更加准确地预测船用柴油机主轴承的润滑特性,运用CMS模态综合法缩减整个机体和曲轴,运用基于质量守恒边界条件的广义Reynolds方程和Greenwood/Tripp接触理论,计入温度影响,建立了基于整个柔性机体下的主轴承热弹性流体动力TEHD混合润滑模型。与单轴承座下的TEHD混合润滑对比,单轴承座计算结果偏于保守,而整机体下参数变化平缓,更接近实际。与整机体模型下的弹性流体动力EHD润滑对比,不计入温度的影响,其计算结果将无法准确反映轴承的整体润滑形貌。相较于另2种模型,基于柔性整机体下的热弹性流体动力混合润滑TEHD模型计算时间增加可以接受。显然,该润滑模型的建模方法具有较高的应用价值。
