空气弹簧静态性能与动态行为分析
Analysis of Dynamic Behavior and Static Performance of Air Spring
摘要
Abstract
Air springs have significant application prospects in quasi zero stiffness system,and their stiffness characteristics are the key to analyzing their performance.A single-convolution bellows type air spring is studied as the research object,and its static and dynamic characteristics are systematically investigated through a combination of theoretical analysis,numerical simulation,and experimental research.A stiffness calculation model for the single-convolution bellows type air spring is established based on gas dynamics theory,and expressions for vertical stiffness and natural frequency are derived.A finite element model of the G40/60 type air spring is constructed by ABAQUS software,and the influence of initial internal pressure on stiffness characteristics is analyzed.Static tests are conducted on a WDW-100 testing machine,where force-displacement characteristic curves under different air pressures are obtained.Load-bearing capacity and static stiffness expressions are derived through polynomial fitting.Dynamic tests are performed on an MTS 831 testing machine,and the effects of air pressure,frequency,and amplitude on stiffness and damping characteristics are studied.Theoretical foundations and design bases are provided for the application of air springs in quasi zero stiffness system.关键词
