摘要 为了判别出矿用巨型卡车在行驶过程中的轻/重车运行状态,提出了一种轻/重车运行状态距离判别分析模型。通过选取矿车行驶过程中的轮胎气压、轮胎温度、速度、加速度和环境温度5个指标作为判别因子,利用97组样本数据作为训练样本,基于距离判别法基本原理,选用马氏距离为判别距离,建立了该判别分析模型。通过训练样本的回代结果以及假设检验结果证明了该模型的合理性。利用该模型,实现了对待判样本的准确判别,说明该模型可以应用到矿用巨型卡车的轻/重车运行状态的判别。

Abstract: In order to discriminate the unloaded/loaded running status of the mine heavy-duty truck in open-pit mine,a distance discrimination analysis model of the unloaded/loaded running status was presented.Five factors including tire pressure,tire temperature,velocity,accelerated velocity and environmental temperature are selected as the discrimination factors,and 97 sets of sample data are considered as training samples.Based on the basic principle of the distance discrimination,the discriminant analysis model is established with Mahalanobis distance as the discriminant distance.The rationality of the model is proved by the back substitution results of the training samples and the hypothesis test results.By using this model,the accurate discrimination of the sample was realized,which shows that the model can be applied to judge the unloaded/loaded running state of the mine heavy-duty truck.
