AI Technical Summary
When faced with sudden load impacts and structural steady-state resonance, the conventional rigid synchronous control strategy of existing gantry crane multi-machine hoisting systems cannot effectively dissipate strain energy, which makes the main beam and related nodes prone to fatigue damage. Furthermore, the existing yield control mechanism lacks multi-dimensional load dynamic transfer and distribution under anti-overturning constraints and low-level electrical rapid response means.
Data is collected by the state perception module, the dynamic impedance yield weight matrix is calculated, and the constraint optimization model of the control solution module and the frequency converter of the torque execution module are combined to realize controlled micro-yield displacement dissipation of high-frequency fatigue strain energy. First-order differential logic unit and fast Fourier transform logic unit are used to process transient impact and steady-state resonance characteristics in parallel. Space load transfer prediction unit and global energy interlocking unit are configured for safety control.
This improves the real-time performance of the system's response to multidimensional alternating stress states, avoids computational delays and the risk of load overturning under traditional control methods, effectively dissipates the fatigue strain energy of the main beam, and ensures the stability and safety of the system.
