摘　　要：为全面有效地评估车辆动力系统的燃油经济性,建立考虑不同路面特征的履带车辆循环工况。收集铺面路、砂石路和起伏土路3种路面的实车运行数据作为原始数据样本,并利用小波分析对数据进行滤波处理。基于处理后的实车数据,综合利用主成分分析法、K均值聚类和马尔可夫链构建3种路面下的典型循环工况,并对构建的工况进行相似度分析。研究结果表明:采用新方法能够有效地构建出符合军用履带车辆运行特点的循环工况,3种路面下循环工况的特征均与原始数据有极高的相似度;3种路面车速-加速度联合概率分布与原始数据的均方根误差分别为0.0356、0.0039和0.0196,新构建的工况能够有效反映履带车辆的真实运行情况。A tracked vehicle driving cycle considering road features is established to effectively evaluate the fuel economy of the vehicle powertrain.The operating data of vehicle on paved road,gravel road and undulating dirt road are collected as original data,and the data are filtered by wavelet analysis.Based on the processed vehicle data,the typical driving cycles under the condition of the three road surfaces are constructed by using principal component analysis,K-means clustering and Markov chain,and the similarity analysis of the constructed driving cycle is carried out.The research results show that the proposed method can be used to effectively construct the driving cycle that resembles the operating characteristics of military tracked vehicles,and the characteristics of the driving cycles under the condition of the three road surfaces have high similarity with the original data,the root mean square errors of the joint vehicle speed-acceleration probability distribution with the original data for the three road surfaces are 0.0356,0.0039 and 0.0196,respectively,so the driving cycle constructed in this paper can effectively reflect the real operation of tracked vehicles.
