Implication

Computational modeling demonstrates enhanced vibration suppression in rotor systems using an optimized magnetic dry friction damper, indicating a reliable design framework for aerospace actuators.

Key Points

To resolve tradeoffs among force output, response speed, and actuator volume in active magnetic dry friction dampers using a multi-objective global optimization framework.
Formulated a parametric analytical model mapping electromechanical couplings, validated with ANSYS finite element simulations.
Developed an improved genetic algorithm with adaptive mutation and random immigration to generate explicit bi-objective and tri-objective Pareto fronts.
Conducted system-level transient dynamic validation on a benchmark rotor platform under sudden unbalance excitation.
Optimized actuator parameters (300 N force, 2 ms response time) reduced initial peak vibration amplitude by 20.39% relative to nonoptimized configurations.
Actuator optimization curtailed dynamic vibration settling time by 73.58% following sudden rotor unbalance.
