摘要:
为探究空气弹簧动刚度特性,基于计算流体力学并采用流固耦合方式分析计算,即在ABAQUS 有限元软件中建立带附加气室空气弹簧固体部分的有限元模型,并在STAR-CCM+ 流体分析软件中建立空气弹簧内部气体部分模型,通过SIMULIA 耦合引擎使得ABAQUS 和STAR-CCM+ 之间进行数据即时交换,最后仿真计算得到空气弹簧动刚度。结果表明:激振频率从1~10 Hz 变化,空气弹簧动刚度变化很大;相同频率下,载荷内压越大,空气弹簧动刚度越大;激振振幅越大,空气弹簧动刚度越大;无论频率高低,激振振幅对空气弹簧的动刚度的影响均较大。
Abstract:
To explore the dynamic stiffness characteristics of air spring, based on the CFD and the fluid-structure coupling method, the finite element solid model of the air spring with an auxiliary chamber was constructed in the ABAQUS, and internal gas part of the air spring was established in STAR-CCM+, and data timely exchange by SIMULIA between ABAQUS and STAR-CCM +, and eventually the dynamic stiffness of the air spring was obtained. The study results show that: when the excitation frequency change from 1 Hz to 10 Hz, dynamic stiffness of the air spring vary markedly; at the same frequency, the greater the load pressure is, the greater the air spring dynamic stiffness is; the greater the excitation amplitude is, the greater the dynamic stiffness of air spring is; the amplitude of vibration has great influences on the dynamic stiffness of air spring.
