Dynamic analysis of air spring vibration isolation systems based on numerical methods
Abstract
Abstract Air springs play a vital role in vehicle suspension systems. This paper investigates their dynamic and static characteristics through experimental and simulation analysis, examining the effects of inflation pressure (0.2–0.6 MPa) and wall thickness (3.5–5.5 mm). A fluid-structure interaction model was established using ABAQUS. Optimisation was achieved through response surface methodology combined with a genetic algorithm, resulting in a 28.6% reduction in transmission rate at 5 Hz and a 23.7% improvement in dynamic stiffness curve flatness. The reliability of the optimised design was validated through 500,000 cycles of load testing.
