摘要：
Structural parameters are key factors affecting mechanical performance of rolling lob air spring (RLAS) . Rolling lob air springs with complex piston contours have characteristics of complex structural parameters, strong nonlinear mechanical properties and constantly changing load-bearing capacity with variation of working height. It is an important way to establish a unified model of nonlinear structural parameters of rolling lob air springs with complex contour based on key design parameters for analyzing and optimizing mechanical properties of air spring at design stage. Here, aiming at the problem of structural parametric modeling of rolling lob air spring with complex piston contour composed of straight line and circular arc, the problem of outer diameter dynamic change of rubber airbag with variation of spring height and the problem of nonlinear mechanical performance caused by complex piston contour, taking inner cone angle of straight line segment contour and circular arc contour radius as key design parameters, the unified model of nonlinear structural parameters of rolling lob air spring with complex piston contour was established to reveal effects of key design parameters on structural parameters and stiffness. The results showed that the maximum relative error between structural parameters predicted by the unified model and test results is 10. 98%, relative errors of static stiffness under different pressures are less than 7%, and maximum relative errors of load-bearing capacity are less than 9% to verify the effectiveness of the unified model of structural parameters; the study results provide a theoretical guidance for refined design of piston contour and prediction and optimization of stiffness and load-bearing characteristics of rolling lob air spring. © 2023 Chinese Vibration Engineering Society.
