Experimental Investigation of Static and Dynamic Properties of Steel–Rubber, Cast Iron–Rubber and Epoxy Granite–Rubber as IC Engine Mount

摘要

The effective way of reducing the vibration transmitted from the engine to the supporting structures is use of mounts. The mounts are used not only to isolate the vibration but also to withstand the static and dynamic loads of the engine. In this work, the mount structural materials are prepared from steel, cast iron and epoxy granite and tested for the structural properties and damping ratio. The mounts manufactured using these materials and natural rubber are tested using the experimental setup for the dynamic behavior with harmonic excitations. The results of the reaction forces exerted and the respective phase angles during the harmonic excitations showed that the epoxy granite–rubber mount has improved natural frequency and vibration isolation.
