| 초록 |
This paper presents a reduced order model of a multi-axle suspension system for medical purpose vehicles concerning unbalanced distribution of the axle loads during various road driving conditions. A twin-rear axle suspension as the load balancing system for limiting the occurring overloads is presented in this study. The modeled twin rear axle suspension has leaf-springs whose center are fixed to the body of vehicle, and each rigid axle is connected to both sides of the spring. The reduced-order model for the target vehicle is developed by combining the conventional bounce model with beam elements. The model is consequently verified by comparing the actual vehicle driving data with the model simulation results. |
