Abstract:
The optimal design technique for minimum power loss in
traction drive continuously variable transmissions is
developed. The mathematical model is developed to
evaluate the traction force and torque in traction drive
contact. Kinematic analysis of general traction drive
contact is conducted to find the best configuration for
minimum power loss. The kinematic analysis and optimal
design problem formulation are performed for two traction
drive configuration as examples of optimal design
procedures. The general forms of objective function and
constraint equations are derived, and the formulated
optimal design problems are implemented to a nonlinear
programming algorithm. The optimal design technique is
summarized from the two optimal examples.
