AI Technical Summary
Existing micro-vibration simulation methods suffer from transient overshoot and slow response speed in low-frequency line spectrum disturbances, leading to drive saturation and making it difficult to achieve high-precision micro-vibration environment simulation.
By combining passive vibration isolation with active vibration isolation technology, and through active excitation and feedforward controller design, transient trajectory planning is performed. The amplitude is modulated using a fifth-order polynomial curve, and a closed-loop feedback control system is designed to suppress ground vibration and realize line spectrum vibration environment simulation.
It effectively reduces the overshoot of the control system, improves the accuracy and controllability of micro-vibration simulation, realizes the accurate reproduction of low-frequency line spectrum vibration environment, and provides reliable environmental support for equipment vibration testing.
