Abstract

The invention relates to a load stimulation device of a servo system and a performance testing device of the servo system and belongs to the field of detection technology and automation technology. The devices integrate three modes of inertia loading, servo motor loading and spring loading, can realize independent loading of three loading modes, two combination loading or simultaneous loading, and can stimulate various loading conditions, such as inertia load, elastic loading, unbalanced load, impact load, time change load and the combination of various loads. Acquired signals of a tested servo system, a torsion rotational speed sensor and an angle sensor are sent to a computer for processing so as to realize the static and dynamic performance test under different loading conditions.

Description

technical field [0001] The invention relates to a servo system load simulation device and a servo system performance test device, which belong to the field of detection technology and automation technology. Background technique [0002] The servo system load simulator is an important equipment for simulation experiments. Its main function is to simulate the actual working environment under laboratory conditions, and apply a load corresponding to the actual working conditions to the system under test, so as to truly reflect the actual performance of the servo system. . Servo systems used under different working conditions are subjected to very complex loads, including inertial loads, elastic loads, unbalanced loads, time-varying loads, and impact loads. [0003] At present, the loading methods generally adopted by the load simulation device are: mechanical loading, electro-hydraulic servo loading, electromagnetic loading and motor loading, etc. The main advantages of mechan...
