Mechatronic transmission design and implementation for dump truck BelAZ-90

The article describes design, investigation and introduction of a new engineering solution for a mechatronic alternating current transmission for dump truck BelAZ-90. The power system of the transmission contains a Diesel combustion engine connected via a shaft with a rotor of an electromagnetically driven traction alternator. Two three-phase stator windings of the traction alternator are connected with two diode bridges which generate a 12-pulse rectification circuit for DC link supply. Asynchronous tractive motors of the left and right driving powerwheels are connected to the outlets of the appropriate self-excited inverters on fifth-generation IGBT transistors FF1800R17IP5. The controls of the power converters of the tractive motors generate the momentum signals for each power-wheel and the mode select lights (hold, cruise control, service modes). DC link voltage control includes adjustment of the alternator drive current using the three-flow regulation system with the DC link current and voltage feedback and with the alternator output voltage feedback. The mechatronic transmission implements anti-slipping and anti-locking functions, as well as the modes of holding the dump truck at zero velocity and speed stabilization (cruise control). The information and diagnosis system performs continuous logging of the main operating parameters and stores the accident pre-history on a SD card. The mechatronic transmission testing at Safonovsky Electric Machine Building Plant and the commercial operation of dump truck BelAZ 75583 at Berezovsky open pit mine, Stroiservis JSC proved high performance capabilities of the design.
