| Ringkasan: | One of approaches to protect devices from unpleasant vibrating disturbances is by
employing a vibration absorber. This paper explores the viability of polysiloxane as raw material,
added with rice husk silica fillers to produce a vibration absorbent sheet. The polysiloxane
reinforced with rice husk sheets were made using hot compression moulding technique. The
samples were tested for its density and tensile tests according to related standards. As for vibration
test, a portable hand grinder was used to estimate the vibration exposure experienced by the users.
The polysiloxane sheets were strapped on the tool’s handle and the vibration exposure was
measured. The result shows that by applying the polysiloxane sheets on the tool grinder reduces the
vibration magnitude by a maximum value of 38 percents. The longest vibration time exposure was
recorded for 6.42 hours, improved by 150 percents from the original vibration time exposure of 2.52
hours. The results also demonstrated that polysiloxane with 4 wt. % rice husk silica was the
optimum combination for vibration application since it produced highest vibration magnitude
reduction and longest vibration exposure time of grinder applications. |
