Abstract
The laminated rubber metal spring (LR-MS) is an equipment used on the mass structure such as building, railway, and huge machining. LR-MS act as an isolator of the structure and help to reduce vibration receive from external force, for preventing form damage on the structure. LR-MS consist of interlayer of rubber layer and stainless-steel layer which is repeatable arranged to form a LR-MS isolator. The stainless-steel layer is a metal plate used to provide strengthens for the LR-MS to withstand heavy structure. This study is done to determine the damping ratio of stainless-steel circular plate which is interlayer with rubber in the LR-MS. The damping ratio of the circular plate will be determined by using two methods are Logarithmic Decrement method and Half-Power Bandwidth method, and the data compute from the DeweTrans software of the experiment will be acquired from the dynamic properties experiment on the circular plate. The analyzed result will be compare to determine the percentage of error occur in this experiment. The result of damping ratio of the experiment on the cantilever beam shows the difference on both theoretical value and experimental value with the 21.13% percent of percentage of error. The experiment consist error during the experiment work was carried out, the error in this experiment are random error, and systematic error that cause the data taken was inaccurate and the experiment categories as unsuccessful test. The propagation of maximum amplitude in 10 cycles in each experiment done, all the peak amplitude is damped constantly varies with time. For maintaining the precision of the result, the experiment has been repeated three times and the average result among the total experiment was taken and recorded in the table. Both methods successfully proving the reliable data and result for determining the damping ratio for stainless-steel circular plate during this study.
