We provide an ice friction model for vehicle dynamics of a two-man bobsled which can be used for driver evaluation and in a driver-in-the-loop simulator. Longitudinal friction is modeled by combining experimental results with finite element simulations to yield a correlation between contact pressure and friction. To model lateral friction, we collect data from 44 bobsleigh runs using special sensors. Non-linear regression is used to fit a bob-specific one-track vehicle dynamics model to the data. It is applied in driving simulation and enables a novel method for bob driver evaluation. Bob drivers with various levels of experience are investigated. It shows that a similar performance of the top drivers results from different driving styles.

雪橇车辆动力学冰摩擦建模在驾驶员评估和驾驶模拟中的应用

我们为两人雪橇的车辆动力学提供了冰摩擦模型，可用于驾驶员评估和驾驶员在环模拟器中。纵向摩擦通过将实验结果与有限元模拟相结合来建模，以产生接触压力和摩擦之间的相关性。为了模拟横向摩擦，我们使用特殊传感器从 44 次雪橇滑行中收集数据。非线性回归用于将特定于鲍勃的单轨车辆动力学模型拟合到数据中。它应用于驾驶模拟，并为鲍勃驾驶员评估提供了一种新方法。对具有不同经验水平的鲍勃司机进行了调查。它表明，顶级车手的相似表现源于不同的驾驶风格。
