Embodiment

[0024] According to the motion angle θ of the loaded object and the direction of the torque spectrum command T, the working modes of the loading device can be divided into four types. Specifies to be loaded the object actuator ( figure 1 The center is the drum) as a reference, looking from right to left, the direction of movement direction θ and the direction of loading spectrum command T is positive in the counterclockwise direction.

[0025] Such as figure 1 As shown, when the direction of motion of the loaded object and the direction of the torque spectrum command are both positive, it is called working mode 1, the chamber A of the loading actuator works in the flow mode, and the chamber B works in the pressure mode; when the loaded object moves When the direction is positive and the direction of the torque spectrum command is negative, it is called working mode 2. The loading actuator A cavity works in the pressure mode, and the B cavity works in the flow mode; when the d...

Abstract

The invention belongs to the technical field of simulation, and particularly relates to a cartridge valve based high-power load simulation system and a using method. The system comprises a loading actuator, a tachometer, a torque sensor, a loading controller, a proportional pressure reducing valve I, a proportional pressure reducing valve II, a proportional pressure reducing valve III, a proportional pressure reducing valve IV, a two-position two-way electromagnetic reversing valve I, a cartridge valve I, a cartridge valve II, a cartridge valve III, a cartridge valve IV, a two-position two-wayelectromagnetic reversing valve II, a one-way valve, a one-way variable hydraulic pump, an oil tank, a torque feedback signal differentiator, a loading shaft axial rigidity proportion unit, an angular velocity instruction calculation unit, a loaded object angle feedback signal differentiator and an angular velocity servo controller. A loading device is simple in structure and low in cost, cavitydivision coordination control over the flow state and the pressure state of the loading actuator is achieved, forced flow caused by active movement of a loaded object is eliminated, the redundant force restraining effect is good, and the load simulation precision is high.

Description

technical field [0001] The invention belongs to the technical field of simulation, and specifically relates to a high-power load simulation system based on a cartridge valve and a use method thereof. Background technique [0002] The load simulator is widely used in aerospace, vehicles, ships and other fields. It is mainly used in the half-physical simulation test. It can track the load spectrum given by the computer in real time and simulate the load on the loaded object in the real environment. Detect the technical performance indicators of the loaded object system. The load simulator simulates the moment load on the hoist, and can test the hoist's load performance, control accuracy, and the stability and reliability of the hoist's gate control system under laboratory conditions. [0003] In the occasions where high-power mine hoists are typical representatives of loading technology requiring large flow and large torque, the traditional load simulation system is restricte...
