Abstract
En 中文
Inertial Continuous Variable Transmissions (ICVTs) are relatively unknown transmission systems. Based on a generated computational model, calibrated with real-world data, and analytical equations, a parametric analysis reveals the influence of each parameter in ICVTs operation. This research provides a clearer understanding of ICVTs and offers practical insights for future transmission system research and development. The study concludes that the effects of nearly all parameters on the output speed are dualistic, depending on the dominance of specific phenomena related to the chosen parameter value. This indicates that, for a given parameter, there may be a positive correlation between the output speed and certain ranges of values, and a negative correlation for others, while maintaining the engine at the same operating point. This suggests the relation is non-linear. The research differentiates the behavioural nuances between inertial and traditional kinematic CVTs, emphasising how some parameter values adjustments, which can be negative for kinematic CVTs, potentially enhance output speed and the transmitted torque in inertial CVTs.
