Design of High-Speed Rolling Bearing Vibration Control System Based on Partial Differential Equations

Vibration behavior is the main cause of resonant displacement in high-speed rolling bearings. Excessive resonant displacement will reduce bearing sensitivity and affect the rotational accuracy of mechanical components. To suppress this displacement, a high-speed rolling bearing vibration control system based on partial differential equations is designed. In terms of hardware, connect the rolling bearing vibration transducer, bearing amplitude control circuit, and rolling speed measurement device as needed; in terms of algorithms, first set the partial differential boundary domain, calculate the numerical solution of the equation and define its expression, then discretize the vibration signal to determine the parameter range and realize the solution of signal parameters. Meanwhile, build a feedforward compensation controller model, improve the compensation control algorithm for fault-tolerant processing of control vectors, perform compensatory control on bearing vibration, and combine with hardware to complete the system design. Experiments show that the system can control the resonant displacement of high-speed rolling bearings within the range of 0-0.5mm, prevent the decrease of bearing sensitivity due to vibration, and ensure the rotational accuracy of mechanical components.
