摘　　要：根据企业对液力变矩器不同工况下流场特性对比分析的需求,结合变矩器工作特点,对变矩器速比在0～1范围内11个均布工况进行CFD数值计算,重点针对几个典型工况的流场分布展开深入分析,寻找这些工况下流场分布规律,最终获得该液力变矩器全流道瞬态特性曲线,并进行特性测试试验,验证该数值模拟方法的正确性,这为企业今后关于变矩器参数改进、性能改良、结构优化、设备配套选型等研究提供有力的理论依据。According to the enterprise＇s demand that the comparison and analysis of the flow field under different working conditions for torque converter, this paper mainly made the CFD numerical calculation for the flow field under 11 uniformly distributed conditions whose transmission ratio was in the range of 0～1, and launched an depth analysis for several field under typical working conditions to find the flow field distribution law of the conditions above. Finally the transient characteristics curve of the whole flow passage of the torque converter obtained and verified to be correct through the characteristic test. It provides strong theoretical basis for enterprise further research about parameters improvement, performance improvement, structure optimization, equipment selection for torque converter.
