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

Abstract

It is important to maintain every machine affecting the process of making sugar to ensure excellent product quality with minimal losses and to accelerate productivity and profitability targets. The centrifuges are widely used in industry today with some being very difficult and critical for surgery, and the collapse of the engine has the ability to cause expensive damage. One of these is the centrifugal machines, and they are expected to be efficient to produce high-quality sugar. Meanwhile, an efficient diagnostic tool to predict the correct time for centrifugal repair is vibration signal analysis namely by attaching the accelerometer sensor to the location of the centrifugal bearing to produce vibration data that is ready to be analyzed. Still, the process requires sufficient insight and experience. The manual method usually used is complicated and requires a lot of time to obtain results of a centrifugal diagnosis. Therefore, this study was conducted to design an intelligent system to diagnose centrifugal vibrations using Artificial Neural Networks (ANN). The situation is involved in applying and training the concept of vibration analysis from spectrum data to ANN to produce diagnostic results according to the spectrum diagnosis reference. The results obtained were quite good with the largest cross-entropy value of 10.67 having 0% error value with the largest Mean Square Error value being 0.0023 while the smallest regression was 0.993. The test conducted on nine new spectrums produced eight true predictions and one false. The system can provide fairly accurate results in a short time. Classification quality improvement can be made by adding training data.

Comparative analysis of classification algorithm: Random Forest, SPAARC, and MLP for airlines customer satisfaction

“…The paradigm of supervised learning can be seen from the Neural Network, which includes the MLP algorithm, which can efficiently find solutions for several linear and non-linear problems, such as the classification process [10] [11]. Moreover, processes in MLP have unique characteristics, such as; 1) Nonlinearity that is reflected in the activity and can be distinguished, 2) One or more hidden layers of neurons to enable the network to solve complex problems, and 3) Interconnection model.…”

Perancangan Sistem Diagnosis Getaran Motor Menggunakan Jaringan Saraf Tiruan Propagasi Mundur

“…Sayangnya cara ini belum dicoba diterapkan untuk mendiagnosis getaran pada motor. Jayasundara et al [25] dan Romahadi et al [26] berhasil menerapkan metode ANN jenis propagasi mundur untuk mendeteksi kerusakan dari pola getaran. Di sini penulis mencoba untuk mempraktikkan penelitian sebelumnya dengan cara yang sama namun dengan media yang berbeda.…”

Effects of Eccentric Training on Balance in Athletes

“…3 Romahadi D et al believe that, there is a significant correlation between slow muscle strength and fast muscle strength in athletes' knee joints; The larger the peak torque value, the stronger the muscle function, and the stronger the body' s ability to maintain balance. 4 In his research, Kolias P pointed out that balance ability is an important factor for improving sports skills, in his research, he proposed that strengthening core strength training in improving balance ability training is an important means for basketball players to improve their skills. 5 Koehler also made it clear in the study: Core strength plays a role in controlling body balance and transmitting power during human movement, which is of great significance to the completion of motor skills.…”
