Abstract

The oil palm fronds chopping machine is one of the most important mechanism in agriculture sector in Malaysia. The machine was used widely over the world in order to provide high quality livestock feed, thus the vibration issue is a main concern for the industry since a high level of vibration on the machine may affect the production and give some negative effects to the labour. The main factor that contribute to the vibration of the chopping machine is on the development of the machine itself. Also, the vibration behaviour of the machine should be recognize or identify first in order to analyse the performance of the machine during run the operation. Oil palm fronds chopping machine have been assembling well with all of their compartment to ensure that the chopping process could be done smoothly. The specimen were freshly collected from field and prepared within the dimension before starting the chopping process. Once the vibration sensor have been attached to the machine at the certain points, the oil palm fronds were ready to be chopped. During run the operation, the data on the overall vibration of the machine at the bearing and the body have been recorded and analysed by the sensor. From the results obtained, the vibration level (ms-2) produce on the bearing during the chopping process by the machine that implemented with four axial blade is 17.6 compared to seven axial blade which is 23.9. While, the vibration level (ms-2) produce on the body for four axial blade is 28.6 compared to seven axial blade which is 44.5. The result gained from the experiments conclude that the most efficient implement should be applied to the machine is the knife with four axial blade as it produce the minimum vibration level on the machine.
