The invention provides a hydraulic simulation test system for non-road mechanical working conditions. The hydraulic simulation test system is characterized by comprising a master control upper computer, an engine controller, a hydraulic absorption and adsorption assembly and a walking power absorption assembly, the engine controller is used for controlling the rotating speed and the torque state of an engine of the non-road machine, and the main control upper computer controls the operation sequence of all hydraulic branches of the non-road machine through the hydraulic absorption and adsorption assembly according to a preset control strategy. The main control upper computer simulates the running resistance of the non-road machine through the walking power absorption assembly. According to the non-road mechanical working condition hydraulic simulation test system and the test method, the problems that related tests of hydraulic drive type machinery can only be carried out by adopting an actual field working m
