摘要
为研究横向互联空气悬架系统中互联管路部件的共振问题,在Solid Works中建立三维模型,并采用ANSYS Workbench对互联管路部件进行模态分析,计算了互联管路部件在气体预应力作用下和流固耦合作用下的固有频率及振型,并分析了电磁阀安装位置及管夹布置位置对互联管路系统模态分析结果的影响。结果表明:考虑流固耦合作用力下的横向互联管路部件的各阶固有频率均高于考虑气体预应力作用下的各阶固有频率,其中一阶固有频率提高率达到156.43%;改变电磁阀安装位置互联管路部件的各阶固有频率变化率为0.93%~30.88%,在适当位置安装管夹固定互联管路系统其一阶固有频率可提高30%以上。研究结果为后续互联管路部件在试验与实车中的应用奠定基础。
In order to study the resonance of interconnected pipeline in a transverse interconnected air suspension system,a three-dimensional model is built with Solid Works,and the modal analysis of interconnected pipeline system is carried out by using ANSYS Workbench. The natural frequency and vibration modes of the interconnected pipeline system under the pre-stress and fluid-solid coupling are compared. The influence of the installation position of the solenoid valve and the position of the clamps on the modal of the interconnected pipeline system is also analyzed. The results show that the natural frequencies of the transverse interconnected pipeline system are increased by the fluid-solid coupling effect,and the first-order natural frequency increase rate is156. 43%. To change the installation position of the solenoid valve,the natural frequency of theinterconnected pipeline is varied,and the rate of change is 0. 93% ～ 30. 88%. The first-order natural frequency can be increased more than 30% by installing the clamp to fixed the pipeline system in the appropriate place. The research results establish the foundation for the following application of the interconnected pipeline system in the test and the actual vehicle.
