A model based on experimental data for high speed steel belt CVT

Knowing that modern small engines can run at speeds exceeding 7000 RPM, a CVT model for high rotating speed applications is proposed. The experimental results show that significant differences lie between the 0–2000 RPM models and the experimental 0–7000 RPM data, even in steady state. Dependencies on rotating speed arise even if the actuation forces are compensated for centrifugal effect. The proposed model is validated for rotating speeds from 0 to 7000 RPM at the input of the variator.
