This paper presents a one-dimensional oscillatory vehicle model with three degrees of freedom (DOF) for analyzing vertical oscillations and their impact on passenger comfort. The model is validated through experimental measurements on three types of roads: a used urban asphalt road, a gravel road, and a newly paved asphalt road. The road profile was generated according to ISO 8608, while passenger comfort was assessed using ISO 2631. The results showed a high correlation between numerical simulations and experimental data, with a maximum deviation of 0.02 m/s2. This study is significant as there have been no precise investigations using low-degree-of-freedom models, demonstrating that such an approach can provide accurate and reliable results in passenger comfort analysis.

摘要

This paper presents a one-dimensional oscillatory vehicle model with three degrees of freedom (DOF) for analyzing vertical oscillations and their impact on passenger comfort. The model is validated through experimental measurements on three types of roads: a used urban asphalt road, a gravel road, and a newly paved asphalt road. The road profile was generated according to ISO 8608, while passenger comfort was assessed using ISO 2631. The results showed a high correlation between numerical simulations and experimental data, with a maximum deviation of 0.02 m/s2. This study is significant as there have been no precise investigations using low-degree-of-freedom models, demonstrating that such an approach can provide accurate and reliable results in passenger comfort analysis.
