Abstract

Vibration is very important to be learned by the student in order to grasp the understanding of how vibration may bring harm to a system and machine and how it can be controlled and surpassed to get the desire condition. The mass-spring-damper simple model made the learning easy as the system and structure is simplified. In this study, the vibration test rig is developed in order to make the teaching and learning simpler and can be understand easier. In order to do that, the test rig will be design from its frame to make it ergonomics and the parameter used in the test rig will be carefully selected so that the test rig experimental test will be the same as theoretical calculation. The gained information from the past studies and research bring a lot of help in developing the vibration test rig. The imbalanced motor is attached at the centre of the beam with both end of beam is attached to the spring to the top of the frame. The rotation of imbalance motor will causing the beam to periodically move up and down from its equilibrium position which is known as vibration. Accelerometer will be used to determine the displacement of the beam. Later, the absorber will be used which will be attached directly under the motor to be compare to the test without absorber. The result will shows that using an absorber will be able to control the unnecessary vibration to prevent harm to the system. The testing result and theoretical calculation will shows almost the same in their graph shape which represent the vibration of the system when forced vibration with and without absorber is tested. The result shows that the test rig is capable to generate such achievement which will help the student to study vibration and applied the knowledge to the system as they learned in class
