External characteristic analysis and stator parameter optimization for a torque converter
Keywords:
flattened HTC, stator, blade, NURBS, optimizationAbstract
The performance of a flattened hydraulic torque
converter is optimized with orthogonal experiment
and response surface method, considering
parameters of its stator blade, defined with nonuniform
rotational B-splines. The optimization
model, with maximum of the stalling torque ratio as
an objective, is determined through an external
characteristic statistical analysis under the new
European Driving Cycle condition. The
optimization results show that the stall torque ratio
is increased by 10.83%, while the highest efficiency
is above 84%.
