Overview

Simulation study demonstrates reduced vibration and structural mass in industrial washing machines under extreme loads, indicating improved dynamic performance and component durability.

Key Points

To resolve excessive vibration during dehydration and balance structural lightweighting with dynamic reliability in industrial washing machines subjected to extreme working loads.
Formulated the vibration isolation dynamic model using the Lagrange method and constructed a rigid-flexible coupling model for the cabinet alongside a refined finite element model for the inner cylinder.
Applied Kriging surrogate models to fit nonlinear correlations between structural design parameters and mechanical stress and frequency responses.
Conducted multi-objective optimization to tune suspension spring stiffness and damping coefficients while reducing structural mass under maximum stress and fundamental frequency constraints.
Cabinet weight decreased by 11.0% and inner cylinder mass decreased by 9.8% without exceeding baseline stress or fundamental frequency limits.
Resonance peak vibration amplitude at the center of mass of the inner cylinder decreased by 58% following suspension parameter optimization.
