| Abstract: | Transmission ratio regulation law is one of the basis of continously variable transmission(CVT) control. Based on this,CVT may exert its eminent performance.This paper researches the optimal elonomy, optimal power operafion curve,and the operational ratio regulation law of CVT mounted on tractor which is based on the experimental data of diesel engine of tractor.A ratio controller for both ratio regulation laws is designed.Ratio regulation law and control are validated by simulation with Matlab/Simulink. |
