Abstract

The invention provides a bi-directional magnetic powder load simulator, and relates to load simulation equipment, which solves the problem in the prior art that an existing load simulator is easily interfered by the motion of a test object. According to the technical scheme of the invention, the magnetic powder loading mode is adopted. In a loading system, the driving members of two magnetic powder clutches rotate, and the driven members of the two magnetic powder clutches are connected with a to-be-tested object. Through changing the electrifying currents of the coils of the two magnetic powder clutches, the torques transmitted to the driven members are changed. The driving members of the two magnetic powder clutches rotate in opposite directions, so that the output torques are in two directions. The torques are loaded onto a to-be-loaded object through a transmission device. At the same time, the torques are acquired by a torque sensor and then are fed back to an industrial control computer, so that the closed-loop control of the system torques can be accurately realized. The bi-directional magnetic powder load simulator is not interfered by to-be-tested objects, and is high in loading accuracy and high in system bandwidth. Meanwhile, the control algorithm of the bi-directional magnetic powder load simulator is simple and reliable. The bi-directional magnetic powder load simulator can be used for testing the performances of motors.

Description

technical field [0001] The invention relates to a load simulation device capable of simulating various load signals, which belongs to the field of servo control and semi-physical simulation. Background technique [0002] At present, in various high-tech fields such as aerospace and weaponry, it is usually necessary to perform dynamic tests on the drive unit or other key components of the product to test its performance to ensure the reliability of the designed product, and to optimize the product to meet Product requirements for performance. To ensure the reliability of the test data, it is necessary to test the tested equipment under the real load environment. However, product testing in a real environment requires a lot of manpower and material resources, and some are even unrealizable, such as seismic fluctuation loads. Therefore, it is necessary to simulate the required load in the laboratory environment, realize the ground half-physical simulation, and conduct dynamic...
