Frequency-Dependent Characteristics of Air Spring

摘要

摘要: 为了研究空气弹簧不同物理参数对空气弹簧动态特性的影响,基于TPL-ASN空气弹簧模型的仿真软件ASDS建立了与试验工况一致的1/4车模型.利用该模型仿真分析节流孔直径、连接管路直径和长度、附加空气室体积、本体体积对空气弹簧频变特性的影响规律,并与试验结果进行对比分析.研究结果表明: TPL-ASN模型较准确地模拟不同物理参数的空气弹簧在不同激振频率下的动态特性;节流孔和连接管路对空气弹簧动态特性的影响主要体现在中频段,在低频段和高频段对空气弹簧动态特性影响较小;附加空气室对空气弹簧动态特性的影响主要体现在中低频段,在高频段对空气弹簧动态特性影响较小;空气弹簧本体对空气弹簧动态特性的影响主要体现在中高频段,在低频段对空气弹簧动态特性影响较小.

Abstract: In order to study the influence of different physical parameters of an air spring on its dynamic characteristics, a quarter-car model consistent with experimental conditions was set up using the simulation software ASDS that is based on the TPL-ASN air spring model. With the model, influence laws of orifice diameter, connecting pipe diameter and length, auxiliary reservoir volume, and air spring bellow volume on frequency-dependent characteristics was simulated and analyzed. The simulation results were compared with the experimental results. The results show that the TPL-ASN model can accurately simulate the nonlinear characteristics of an air spring with different physical parameters at different excitation frequencies. The influence of the orifice and connecting pipe on dynamic characteristics of air spring is mainly reflected in the middle frequency range, and is less affected in low and high frequency ranges. The influence of the auxiliary reservoir volume on dynamic characteristics of air spring is mainly reflected in low and middle frequency ranges, and is less affected in the high frequency range. The influence of the air spring bellow volume on dynamic characteristics is mainly reflected in middle and high frequency ranges, and is less affected in the low frequency range.
