Description

technical field [0001] The invention belongs to the field of earthquake simulation experiment devices, and relates to a vertical earthquake simulation experiment platform based on fuzzy control. Specifically, it is a hydraulically driven, electro-hydraulic servo control system based on fuzzy control, which is used to simulate vertical earthquake test equipment. It is mainly used for the performance test of the hydraulic cylinder type vertical vibration isolation device. Background technique [0002] Domestic and foreign research on earthquake simulation test benches is mostly limited to mechanical and electrical technology, which is a large-scale equipment with complex structure, large volume, high cost, and low response accuracy, which cannot truly simulate seismic waves. The unique advantages of hydraulic technology, high frequency response, easy control of flow and pressure, and reasonable design can simulate seismic signals very well. At present, hydraulic technology is...
