Intelligent System for Gearbox Fault Detection & Diagnosis Based on Vibration Analysis using Bayesian Networks

Abstract

Moving energy from one machine to another and functioning to reduce speed while increasing torque is the ability of the gearbox. Due to many components and the structure between the components is fairly complex, thus to be able to detect the initial damage, sophisticated methods is needed. Vibration analysis is a method that has been effective in detecting the initial damage that occurs in machine. But it takes time and costs are not small to implement. The purpose of this study is to create an intelligent system capable of detecting gearbox damage based on data obtained from vibration measurements. Merging of two methods of vibration analysis and Bayesian networks is done to be able to design the system with the expected results. A series of multistate nodes are applied to the network and a system review is performed. Results are given and compared with results provided by the manual analysis. The results indicate that the system is feasible and reasonable which can assist inidentifying gearbox damages. This study definitively answers the problem of how to design an expert system capable of replacing the work of an expert on vibration analysis services.

Perancangan Sistem Diagnosis Getaran Motor Menggunakan Jaringan Saraf Tiruan Propagasi Mundur

“…Karena berkembangnya suatu alat perlu juga adanya ketrampilan seorang insinyur untuk mempermudah orang lain mengetahui penyebab getaran itu sendiri dan bagaimana cara penanganannya. Maka dari itu penulis mencoba untuk membuat suatu sistem pintar untuk mendiagnosis suatu motor yang mengalami kendala dengan cara memasukkan data spektrum dari alat ukur getaran [16]- [18]. Dengan menggunakan metode ANN diharapkan dapat membantu dalam mengatasi masalah-masalah yang sering terjadi pada motor [19]- [21].…”

Real Time Assessment of Novel Predictive Maintenance System based on Artificial Intelligence for Rotating Machines

“…After integrating the proposed architecture into the studied system, we could have real-time system data, leading to continuous system monitoring. As a result, the ISO10816-3 standard was exploited to monitor the whole system and detect the first signs of failure [24]. In this case study, the motor rotates at a speed of 1200 rpm and has a power of 2.2Kw.…”

The Implementation of Artificial Neural Networks in Designing Intelligent Diagnosis Systems for Centrifugal Machines Using Vibration Signal

“…The condition is involved determining the requirements by comparing the overall vibration with the ISO standards while the damage location was detected using the spectrum or frequency domain [11].…”
