Abstract

Salah satu kerja mesin otomotif adalah kinerja idle speed yang secara signifikan dipengaruhi oleh parameter kontrol pada electronic control unit (ECU). Pada mesin, idle speed merupakan kompromi antara kecepatan mesin rendah untuk menghemat bahan bakar dan kemampuan untuk menolak gangguan dengan baik. Gangguan putaran mesin terjadi karena permintaan listrik pada alternator, yang mana dengan cepat akan menyebabkan naiknya kecepatan mesin sehingga bahan bakar yang di injeksi akan lebih banyak. Idle speed pada penelitian ini akan dikontrol menggunakan metode pengaturan robust multi input multi output (MIMO) yang mana sistem akan lebih kuat atau robust terhadap gangguan yang diberikan, kemudian menghasilkan perpaduan performance kecepatan optimal dengan emisi gas buang yang dihasilkan dalam seperti yang diinginkan serta waktu yang digunakan untuk kembali pada kecepatan idle speed yang diingikan lebih cepat.

Abstract

This research focuses on the potential for vibration energy from the use of eccentric masses in dynamic rotors to become an electrical energy source. Prior studies on eccentric mass in dynamic rotors were primarily concerned with examining the rotor's vibrational characteristics; however, little research was done on converting vibrational energy into electrical energy. The purpose of this study is to ascertain the maximum amount of electrical energy that can be produced by dynamic rotor vibrations using an eccentric mass. Utilizing an electromagnetic energy harvester, an experimental study is the methodology used. With a rotor rotation speed of 450 rpm, the eccentric mass variations used are 6.5 grams, 8.5 grams, and 10.5 grams. Matlab is used in this research to process data. The highest energy, using an eccentric mass of 8.5 grams, was found to be 24.15 mV. Nevertheless, this study shows that while the eccentric mass has an impact on the amplitude, it has no effect on the voltage. In order to increase and improve the efficiency of the electrical energy produced, further research on the utilization of vibration energy from dynamic rotors can be guided by the findings of this study

Abstract

Human existence has been significantly impacted by the growth of information and technology, particularly in relation to the requirement for effective mobility. But as a car ages, symptoms that affect its performance and safety start to show. These symptoms are a serious worry. Interference with car parts, such coils, is one issue that can have a major effect on driving safety and performance. Vibration analysis techniques have been successful in addressing this problem by detecting damage to different car parts. With the intention of comprehending piston motor vibration characteristics at different rotational speeds. The piston motor was used to collect vibration data at three distinct speeds: 900 rpm, 1500 rpm, and 3500 rpm. Both the Hilbert approach, which offers profound insight into frequency energy, and an FFT analyzer, which produces clear frequency spectrum information, were used in the analysis. The findings demonstrated that vibration characteristics changed in response to variations in reciprocating motor speed. On the other hand, the average frequency energy tends to remain constant across a range of speeds, suggesting that the features of reciprocating motors may be complicated and not very affected by variations in speed. According to this study, different perspectives on the vibration characteristics of piston motors operating at different speeds can be gained by utilizing vibration analysis techniques like FFT and Hilbert. Improved comprehension of this phenomenon could have a significant impact on maintenance initiatives and performance analysis of vehicles. To fully understand the complexity of vibration characteristics in reciprocating motors at various speed conditions, more research will be needed

Abstract

The utilization of vibration energy from a 4-stroke engine as a potential source of electrical energy. Previous studies have focused on analyzing the vibration characteristics and frequency response functions of the 4-stroke engine, but there is a lack of research on harnessing vibration energy as a source of electrical energy. Therefore, this research aims to fill this gap by developing a system to harness the vibration energy from the 4-stroke engine, making it a primary focus of the study. The method employed is an experimental study involving data collection using an FFT Analyzer and Matlab. The research results indicate the presence of several mode shapes in the 4-stroke piston motor. The energy harvesting device utilized is of the electromagnetic type. However, the research reveals that the utilization of vibrations from the 4-stroke piston motor as a source of electrical energy is still not efficient and requires further development. There are various mode shapes in the 4-stroke piston motor at different rotational speeds, but the electromagnetic energy harvesting device used is unable to generate significant electrical energy. Therefore, this research provides a foundation for conducting further research in utilizing the vibrations of a 4-stroke piston motor as a more efficient source of electrical energy

Abstract

Milling machines are machines used in the production process. The time required during the machining process must be more efficient in order to obtain the desired production capacity. The aim of this paper is to utilize vibrations originating from milling machines in industry as a source of Harvesting Energy Vibration. The research was carried out by varying the feeding depth of the milling machine so that it could be seen how much stress was produced. The Lushan Model ZX32 milling machine was used in this research, where vibrations from the vibration source were measured using an FFT Analyzer connected to an Accelerometer Sensor and Harvesting energy vibration connected to an Oscilloscope. Meanwhile, the workpieces used in this research were Aluminum 5052 and PVC. The results of the research were that on PVC material with an ingestion depth of 1 mm, the vibration frequency at 210 rpm was 71 Hz, the amplitude was 1.38 mm/s2, resulting in a harvesting energy of 6.449 mV. And the results of research using aluminum at 210 rpm rotation with a feeding depth of 3 mm obtained a vibration frequency of 90 Hz with an amplitude of 1.508 mm/s2 producing a harvesting energy of 5.856 mV. The research results show that the PVC material produces higher harvesting energy vibration at a depth of 1 mm, and the aluminum material produces higher harvesting energy vibration at a depth of 3 mm
