Abstract


This paper presents some results on the survey of the impact of silica and black carbide on the mechanical – physical properties and vibration resistance of the rubber blended on natural rubber (NR) and synthetic styrene butadiene rubber (SBR), for application in manufacturing diesel engine mounts. Based on this research, the article also introduces some results in building up anti-vibration rubber and the process of diesel engine mounts manufacture. Development of the method to test the vibration resistance of the diesel engine mounts has initially resulted in some good results such as the natural frequencies are lower than 20 Hz and the damping factor is higher than 10.


Keywords


anti-vibration rubber, engine mounts.
