Abstract

This paper presents the results of research on the vibration of the Hyundai Universe bus using an air suspension system and mechanical suspension system when it is run at different speeds on random road surface profiles according to ISO 8608:2016. The research results show that the used air suspension system ensures smooth movement and dynamic safety according to TCVN 6964:2008 (ISO 2631:2003) and VDI 2057:2017 standards. The maximum vehicle speeds on different road classes varied from 105km/h to 65km/h. A vehicle with an air suspension system provided a smaller root mean square of vibration acceleration RMS(Z) than a vehicle with a mechanical suspension system. The root means square of the wheel load RMS(Fz) of a vehicle with an air suspension system is about 99.6% of that of a vehicle with a mechanical suspension system.

空气悬架客车在随机路面上以不同速度行驶时的振动特性研究

本文根据ISO 8608:2016标准，对现代宇宙客车使用空气悬架系统和机械悬架系统在随机路面上以不同速度行驶时的振动进行了研究。研究结果表明，所使用的空气悬架系统确保了TCVN 6964:2008 (ISO 2631:2003)和VDI 2057:2017标准的平稳运行和动态安全。不同道路等级的最高车速从105公里/小时到65公里/小时不等。采用空气悬架系统的车辆的振动加速度均方根RMS(Z)比采用机械悬架系统的车辆要小。采用空气悬架的车辆的轮载RMS(Fz)的均方根约为采用机械悬架的车辆的99.6%。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
