Abstract
In this paper, the mechanism of metal-belt continuously variable transmission (CVT) in the transitional state is analyzed. The acceleration signal of the CVT system in vehicle transmission test rig is picked up when the system is in operation under different condition. The vibration characteristic of the CVT system in the transitional states is investigated online by the means of three-dimension waterfall at constant interval. The distributing rule in frequency domain and relationship between the speed change ratio and torque are obtained. The method and results obtained from the study are significant to theory and practice.
