Dynamic Performance of an Underground Trackless Rubber Tyred Vehicle Driven by Flameproof Diesel Engine

Original scientific papers The trackless rubber tyred vehicle (TRTV) is an important transporting equipment of underground coal mine auxiliary transportation system in the world. Presently, most TRTVs are driven by flameproof diesel engine. However, few researches were focused on their dynamic performance in the past. In this paper, the characterizing parameters and influencing factors of the dynamic performance of a flameproof diesel engine driven TRTV were summarized and discussed firstly. Then the basic dynamic equations of the TRTV were established. Finally, the dynamic performances of the WCQ-3B type TRTV were simulated by ADVISOR. And some important dynamic performance parameters such as maximum speed, acceleration time and maximum gradability were discussed by simulation. What is more, the fuel economy and emission performance of the vehicle were also analysed. It is shown that the dynamic performance of WCQ-3B type TRTV can satisfy the design and usage requirements of underground coal mine.
