The paper obtains motor pressure, flow and speed and the engine speed curves with time by theoretically analyzing closed hydraulic system of wheel walk engineering machinery and establishes a mathematical model of the system and AMESim simulation model. The simulation curves show that in some cases the external loads react against motor and drive motor speeding and then motor outlet flow increase that leads to the pressure of low-pressure side increasing and the pressure of high-pressure side reducing. The mutation of system pressure drives bump and engine speeding that equates to the engine speed is lower than the speed corresponding to the motor flow, which is engine stall problem. The simulation results show that the basic reason of engine stall is walking condition mutation leads to motor speeding and system pressure mutation and then motor reacts against bump and engine.
