液力变矩器早期多凭经验研制。目前国内资料，尚未有较理想、实用和现成的计算方法，人们为完善建立于一元束流理论基础上的设计方法，进行了多方面的研究工作。我们研制开发的ＴＹ２００型液力变矩器，采用理论计算和试验方法相结合，在研究其工作轮几何参数对性能方面取得了重大突破。在改变泵轮、涡轮叶栅的进出口角度差值对提高液力变矩器性能参数的研究取得了可喜的进展，本文将详细介绍这种改善和提高其性能参数的原理、方法和结果
Torque converter more early experience with the development. At present, there is no ideal, practical and ready-made calculation method for the domestic data. People conducted many research work to perfect the design method based on the theory of one-element beam. The TY200 Torque Converter developed by us is a combination of theoretical calculations and test methods. It has made a major breakthrough in the performance study of its working wheel geometry parameters. In the change of the impeller pump, turbine cascade angle of the import and export of torque converter to improve the performance parameters of the study made encouraging progress, this article will detail the improvement and improve its performance parameters of the principles, methods and results
