Research of Driving Cycle Construction for Electric Drive Mining Truck Based on Travelling Analysis Method

This paper is concerned with the driving cycle construction for the electric drive mining truck based on travelling analysis method. Firstly, the complete operation data of the dump truck is collected, which is based on the continuous transportation test on an open pit road. Secondly, according to the travelling analysis method, a single duty cycle data separated from the multi-group dump truck duty cycle data, is divided into short travelling kinematic sequences. Next, based on the driving characteristics, ten characteristic parameters are selected. Through the principal component analysis and density peak clustering analysis, the data dimension is reduced to three principal component, and then the classification of the kinematics sequences is obtained. Further, a typical driving cycle for mining truck can be built by extracting kinematic sequences from each category. Finally, compared with the actual data, the typical driving cycle can strongly reflect the operating characteristic of electric drive mining truck on the open pit road.
