Radial vibration damper (RVD) mechanism validation for long thin shaft at lathe machine

Abstract

Currently, the metal working in manufacturing industry is growing rapidly, taking in mind that production activities cannot be separated from the use of machinery as a support for its operations. The excessive vibration will reduce the effectiveness of the engine, furthermore the engine will be irreparable. One way to reduce the excessive vibration from rotating shaft system at lathe machine is by using Radial Vibration Damper (RVD). This aims of this study are to reduce the vibration acting on a long thin shaft using RVD and to validate the experiment’s results and simulation’s results using the Independent T-test sample method. The position of RVD which is laid on a long thin shaft was varied. The working frequencies of the lathe machine were 320 rpm, 540 rpm, and 900 rpm. The results show that the simulation results correspond well to the experimental results. The maximum vibration reduction of a long-thin shaft occurred at the working frequency of 900 rpm for both the experimental method and the simulation method. The experimental results presented that the maximum vibration reduction of the shaft in the X-axis direction is 67.51% at point 4 (midspain) and the reduction in the Y-axis is 61.47% at point 3. While, the maximum reduction from simulation method occurred in the X-axis is 65.83% and in the Y-axis is 75.78%.Currently, the metal working in manufacturing industry is growing rapidly, taking in mind that production activities cannot be separated from the use of machinery as a support for its operations.
