ABSTRACT
Hydrodynamic torque converter which realizes energy and power transmission function is an important part of transmission system of automobile and construction machinery. There are a lot of evaluation indicators for the performance of hydrodynamic torque converter, for example, launch torque ratio, the maximum efficiency, impeller launch torque coefficient, high efficiency area and so on (Zhu J.C., Liu Z. 2013). Most of the current studies on how to accurately evaluate hydrodynamic torque converter performance just stay in the evaluations method with single or multiple weights. It actually reflects the users’ demand from different aspects.
