Experimental study and numerical analysis for vibration isolation performance on open trench and wave impeding block combined vibration isolation barrier
https://orcid.org/0000-0003-4709-2419
Abstract This paper presents a series of laboratory tests to investigate the vibration isolation performance of open trench and wave impeding block (WIB) combined vibration isolation barrier. To study the vibration isolation performance of open trench-WIB, design the 15 pairs of trials, including comparison with other vibration isolation methods, and the variation of vibration isolation performance with the depth, width, and thickness of open trench-WIB. The experiment is validated by FEM results with vibration isolation performance. The experimental results show that the vibration isolation effect of open trench-WIB combined vibration isolation barrier is better than that of the open trench at various excitation frequencies, and it is most obvious in the low frequency band. In addition, the effects of trench depth, wave barrier depth, barrier thickness, and barrier length on the vibration isolation performance of the open trench-WIB combined vibration isolation barrier are discussed. The research results are of great significance to guide the design of engineering vibration isolation.
Highlights A combined vibration isolation barrier is formed by setting a certain depth of wave barrier below the open trench. The vibration isolation performance of open trench-WIB is studied. The influence of material parameters on the vibration isolation performance of open trench-WIB are discussed.
