Non-track split-type hydraulic motor train unit experimental platform and a steering control system thereof

The invention relates to a non-track split-type hydraulic motor train unit experimental platform and a steering control system of the non-track split-type hydraulic motor train unit experimental platform. The non-track split-type hydraulic motor train unit experimental platform comprises two or more train bodies which are connected in series, the train body in the first section is called a reference train, the train bodies connected behind the reference train are called a transportation train set, and the transportation train set is composed of one or more train bodies connected in series. The non-track split-type hydraulic motor train unit experimental platform is characterized in that the motor train unit track following control strategy that the reference train plans a path and the transportation train set follows the reference train is adopted and through an similitude experiment, the mode that a power source train in the hydraulic motor train unit is connected with a power transportation train set in series can be simulated. Signals are collected and provided by the reference train, the transportation train set automatically follows the track of the reference train, and therefore single-person driving can be achieved. Theoretically, the number of the train sets can be limitlessly expanded.
