AI Technical Summary
Existing electric drive gearboxes struggle to achieve high robustness and adaptive wide-bandwidth, wide-range vibration suppression under high speed, variable load, and wide operating conditions. Traditional control methods suffer from limited stiffness adjustment range, lag in frequency response, complex structure, or insufficient reliability.
By employing a non-circular gear adjustable superstructure, and by designing the pitch curve parameters and meshing phase of the non-circular gear, combined with electromagnetic or servo drive, nonlinear, wide-range and continuously adjustable stiffness characteristics are achieved. A set of nonlinear vibration differential equations is established and solved by numerical integration method. The non-circular gear superstructure is adjusted to achieve precise control.
It achieves real-time and precise control of electric drive gearbox under complex working conditions, has a wide range of vibration suppression capabilities, high structural integration, low adjustment energy consumption, good programmability and stability, and fills the relevant technological gap.
