基于瞬态流场分析的YJ系列液力变矩器性能预测
|
摘要
为了分析液力变矩器的流场特性,文章对YJ某型液力变矩器进行建模和数值模拟。模型采用多叶排全流道的瞬态几何模型,仿真得出的数据和实测力矩数据进行对比,结果表明应用多叶排流道全流道的几何模型具有较高的准确性和可靠性。
本文的主要内容有:
1)介绍了液力变矩器的发展历史、应用范围、传动原理及研究现状。
2)分析计算流体力学的基本流动方程以及湍流的模型理论。
3)用PROE软件对液力变矩器进行三维实体造型,获得液力变矩器各个工作轮流场模型,然后使用GAMBIT进行网格划分前处理,得到理想的离散网格。
4)对流道进行一些假设,在FLUENT中设置边界条件,选择合适的湍流模型以及解算模型,设置收敛条件,调整松弛因子,并进行了各个工况下的流场的数值计算。
5)据FLUENT计算结果,分析在二个典型工况下,各个工作轮流道的速度和压力分布、进口面流线特征。针对其分布特点,分别对泵轮、涡轮、导轮提出一些改进方案。并且对变矩器流场进行了综合分析。
6)数值模拟液力变矩器内流场,并与试验结果相对照,验证分析数值模拟准确性,深刻揭示液力变矩器内流场特征形态及工作机理;
7)全文进行总结:
本课题的研究突破了原有一元束流设计理论,可以缩短设计周期、减少试验次数、提高设计精度、改善产品的传动效率,对新产品设计开发和现有产品改型提供强有力的技术支撑。
