Abstract

Dalam kehidupan sehari-hari, sering ditemukan kasus yang berkaitan dengan getaran. Getaran yang terjadi mengakibatkan banyak gangguan pada proses permesinan tersebut, dan juga menurunkan umur mesin. Getaran yang dihasilkan pada saat sistem beresonansi sangat berbahaya bahkan mampu menghancurkan sistem tersebut. Oleh karena itu getaran yang terjadi harus direduksi atau dikurangi. Dengan menggunakan sebuah alat pereduksi getaran yaitu Dynamic Vibration Absorber (DVA). Prinsip kerja dari metode DVA adalah penambahan sistem yang terdiri dari massa, pegas, dan damper tambahan pada sistem utama. Sistem tersebut dapat meredam getaran yang terjadi pada sistem utama Pada penelitian tugas akhir ini dilakukan validasi terhadap studi eksperimen dan simulasi yang telah dilakukan oleh Intan Mahardika [3] dan Nira Asfarina [2]. Dimana pada penelitian yang dilakukan oleh Intan merupakan studi eksperimental, sedangkan Nira melakukan studi simulasi tentang reduksi respon getaran translasi, rolling, dan pitching menggunakan TMVA. Tujuan dari penelitian ini adaah mencari dan memperkecil error menggunakan metode uji-T. Adapun variasi yang diberikan dalam penelitian ini, yaitu variasi jarak penempatan mekanisme TMVA dari pusat plat simulator getaran), dan jumlah variasi Massa Absorber yang digunakan (2 koin, 4 koin, dan 6 koin). Dari penelitian ini diapatkan hasil yang valid antara hasil simulasi dan eksperimen dibuktikan dengan hasil yang mendekati sama dengan error yang didapatkan sangat kecil. Dari hasil validasi arah gerak translasi didapatakan reduksi respon percepatan paling tinggi di node 5, validasi arah gerak rolling didapatakan reduksi respon percepatan paling tinggi di node 6, validasi arah gerak pitching didapatakan reduksi respon percepatan paling tinggi di node 9, dengan rasio massa TMVA terhadap massa utama yang relatif mampu mereduksi getaran baik arah translasi, rolling, dan pitching berdasarkan penelitian ini adalah 1 : 20.

In the use of machines every day, there are often cases related to vibration. The vibrations that occur cause a lot of interference with the machining process, and also reduce engine life. The vibrations produced when the system resonates are very dangerous and even able to destroy the system. Therefore vibrations that occur must be reduced using a vibration reduction device, Dynamic Vibration Absorber (DVA). The working principle of the DVA method is the addition of a system consisting of mass, spring and additional dampers to the main system. The system can reduce vibrations that occur in the main system In this final project, validation of experimental and simulation studies has been carried out by Intan Mahardika [3] and Nira Asfarina [2], wherein the research conducted by Intan was an experimental study, while Nira conducted a simulation study about the reduction of translational, rolling, and pitching vibration responses using TMVA. The aim of this study is to find and minimize errors using the T-test method. The variations given in this study are variations in the placement distance of the TMVA mechanism from the center of the vibration simulator plate, and the number of variations of Mass Absorber used (2 coins, 4 coins, and 6 coins). From this study, valid results were obtained between the simulation results and the experiments proved by the results that were close to the same with the errors obtained were very small. From the results of translational direction validation, the highest acceleration response reduction at node 5 is obtained, rolling direction validation is obtained by reducing the highest acceleration response at node 6, with the TMVA mass ratio to the main mass which is relatively capable of reducing vibrations in both the translation, rolling, and pitching directions equal to 1:20.
