Abstract

An analysis of the strength of the material on the framework of the digital triaxial apparatus to increase the maximum working capability to 50 kN has been performed. A digital triaxial device is a test machine used to determine the properties of a soil sample. Analysis of the framework of this tool is needed to see the character of the material used so as to obtain maximum performance to support the performance of the digital triaxial device. The frame in question consists of a bottom base, two poles, and a beam rod positioned at the top of the pole. The analysis performed using 3D Solidworks software utilizes structural analysis features. Pressures of 50 kN are given in a vertical direction so as to press the midpoint of the bottom base and the beam rod, both of which are attached to the pole using a nut as anchoring. The analysis result shows that Stress Von Mises maximum vallue that works on parts is 1.664,7 kgf/cm2.  Keywords: Triaxial Digital, load- frame, structure analysis, 50 KN

Abstract

Analysis of the effect of using a chain and sprocket on the motor power consumption in mobile robot platform, which uses a system of tracks has been done. This study is currently important to avoid mistakes when selecting motor power to be choose when designing a mobile robot that uses a lot of chains and sprockets. The results of this research might be used as a basis for designing mobile robot track systems, especially in predicting an increase the power consumption of the motor. In the experimental set-up, 20A ACS712 sensor was coupled in series to the motor cables to get the current consumption, while the module voltage divider was used to retrieve the value as the voltage.  The sensors were connected to the Arduino Nano V3 microcontroller to process the data obtained were then stored and displayed on a laptop. Tests were conducted on five conditions, namely the complete transmission (full load), minus one flipper, minus two flippers, without the track wheel (connected to the shaft), and free-load motors. The results showed that use of chains and sprockets at full load conditions increases the consumption of motor power of 215% compared with that of no load.Analisis pengaruh penggunaan rantai dan sproket terhadap konsumsi daya motor pada platform mobile robot yang menggunakan sistem track telah dilakukan. Penelitian ini saat penting dilakukan untuk menghindari kesalahan pada saat pemilihan daya motor yang akan digunakan ketika rancang bangun mobile robot yang banyak menggunakan rantai dan sproket. Hasil penelitian ini diharapkan dapat digunakan sebagai dasar dalam merancang mobile robot sistem track, terutama dalam memprediksi peningkatan konsumsi daya motor. Pada set-up pengujian, sensor ACS712 20A dipasangkan secara seri pada kabel motor untuk mendapatkan konsumsi arus, sedangkan modul pembagi tegangan digunakan untuk mengambil nilai tegangan. Sensor-sensor tersebut dihubungkan dengan mikrokontoler Arduino Nano V3 untuk mengolah data yang didapat yang kemudian disimpan dan ditampilkan pada laptop. Pengujian dilakukan pada lima kondisi, yaitu transmisi lengkap (beban penuh), minus 1 flipper, minus 2 flipper, tanpa track wheel (terhubung dengan poros), dan motor bebas beban. Hasil penelitian menunjukkan bahwa penggunaan rantai dan sproket pada kondisi beban penuh meningkatkan konsumsi daya motor sebesar 215% dari pada konsumsi daya pada keadaan bebas beban.
