摘要
为了能更好地研究找出一些可能影响YJH265型液力变矩器传动效率的影响因素,从而大幅度加深对流场的传动特性认识,并为下一轮变矩器的技术改进提供依据,以达到改善和提高变矩器的传动性能的主要目的。通过流体力学建模数值计算的理论方法,运用流体力学数值模拟和性能试验研究相结合的计算方法对变矩器内流场中的瞬态速度场和压力场进行分析,并将性能试验结果与之对比。试验结果表明:变矩器内流场数值计算所模拟的原始特性曲线与试验所得的原始特性曲线已经非常吻合,计算结果误差通常在5%以内。因此,基于三维流场的瞬态数值的模拟结果较全面地反映了YJH265型液力变矩器内部真实的流场,为液力变矩器的设计优化提供了可靠的依据。
In order to find out the factors influencing the transmission efficiency of the YJH265 torque converter,the understanding of the flow field characteristics is deepened and the basis for the improvement design of the next torque converter is provided,so as to improve the performance of the torque converter.In this paper,t he transient velocity field and pressure field in the flow field of YJH265 torque converter are analyzed by means of computational fluid mechanics modeling and numerical simulation combined with experimental research,and the results are compared with the results of performance test Comparative analysis.The results show that the original characteristic curve of the numerical simulation of the flow field in the hydraulic torque converter is in good agreement with the original characteristic curve obtained from the experiment,and the calculation error is less than 5%.It can be seen that the transient numerical simulation method based on three-dimensional flow field reflects the real flow field inside YJH265 hydraulic torque converter comprehensively,which provides a reliable basis for the design optimization of the hydraulic torque converter.
