Abstract

Kualitas sambungan rivet berperan penting untuk menahan beban khususnya pada struktur badan pesawat. Umumnya terdapat dua pengaturan susunan rivet yakni zig-zag dan inline. Penelitian ini bertujuan untuk menganalisa kekuatan kedua jenis sambungan rivet tersebut. Pengujian spesimen dilakukan dengan 2 cara, yakni pengujian secara riil yang mengacu pada standard EN ISO 12996:2013 tentang pengujian destruktif pada sambungan dan pengujian secara numerik menggunakan perangkat lunak Ansys 2020 R2. Dua spesimen uji tersebut masing-masing memiliki susunan rivet zig-zag dan inline dengan diameter rivet Ø 3,2 mm dan pelat Al 2024-T3 tebal 0,8 mm dan lebar 37 mm. Hasil pengujian Tarik menunjukkan bahwa susunan rivet zig-zag dapat menerima beban maksimum sebesar 6,01 kN sedangkan susunan rivet inline 5,73 kN. Sedangkan pengujian numerik menunjukkan bahwa tegangan maksimum ekuivalen von-Mises pada susunan rivet zig-zag sebesar 930,8 MPa sedangkan susunan rivet inline sebesar 865,1 MPa.

Abstract

The Computer Numerical Control machine is capable of making circular paths by moving two axes simultaneously in one of the XY, XZ, or YZ planes. If the coordination of the two axes is not good, it will cause circle interpolation errors that affect the roundness error in the machining workpiece. The error of the movement of the two axes can be measured using a double ballbar, to find out the error of the movement, it is varied with three feeding speeds. The research method used is the method of comparative analysis of double ballbar measurement results. some information from the measurement results is the error value of Circularity, Backlash, Squareness, Straightness, and Center offset. Feeding speed is very influential on geometric errors, the greater the value of feeding speed, the greater the error value. In addition to feeding speed, there are many factors that affect the results of double ballbar measurements, including ballscrew, clearance, servo mismatch, test repetition, etc.

Abstract

This PA Fan is one of the vital components in the generating system that functions to drain air and carry fuel (coal) from the pulverizer to the boiler burner. The research has a focus on designing methods to reconstruct the blades in order to increase independence to maintain the reliability of turbo engine equipment. Damage to axial turbo engine equipment generally occurs as a defect in the blades. The method of self-constructing blades needs to be carried out to increase the speed of the repair process. The limitation in this study is that the blade airfoil profile is adjusted to the standards of the National Advisory Committee for Aeronautics (NACA). The benefit of the PA Fan blade reconstruction process is to find the technology of the PA Fan blade product and the basic concepts of the product design process as desired by the initial maker (design intent). The research methods used include: Measurement and geometric modeling of the PA Fan blade using the Mitutoyo Cyrsta-Apex S9106 Coordinate Measuring Machine which is connected to a non-contact laser scanner Mitutoyo Surface Measure 606 to obtain a collection of many coordinates of the measurement results (point clouds), then process point clouds processing to obtain a 3D model of the measurement results, after that identify the airfoil with the NACA standard, and the final stage is to process machine drawings of complete components with geometry specifications.

Abstract

Teknologi baru terkait instrumen inspeksi geometri yang memiliki sifat kecermatan, ketelitian, ketepatan, kecepatan, serta fleksibilitas yang baik dilakukan pada Mesin Ukur Koordinat (Coordinate Measuring Machine). Penggunaan laser scanner sebagai instumen ukur memiliki kelebihan kecepatan akuisisi titik pengukuran cepat sehingga sesuai untuk menginspeksi komponen yang memiliki permukaan yang kompleks. Dalam penelitian ini, dikaji metode pengukuran profil pada komponen sudu rotor Primary Air Fan yang tergolong sebagai salah satu mesin turbo. Fokus pada penelitian ini adalah penjabaran mengenai proses inspeksi toleransi profil garis pada umumnya sudu mesin turbo, khususnya sudu Primary Air Fan PLTU 660 MW dengan mengacu pada ISO TR 5460 dengan alat ukur 3D laser scanner. ISO TR 5460 merupakan standard laporan teknis yang berisikan panduan untuk memverifikasi toleransi geometri yang terdeskripsi pada ISO 1101. Proses inspeksi geometri profil garis pada sudu mesin turbo dengan alat ukur 3D laser scanner secara umum bekerja dengan cara membandingkan antara reference data dengan measured data. Reference data merupakan CAD model sedangkan measured data merupakan point clouds yang sudah dilakukan proses triangulasi/meshing yang didapatkan dari hasil pengukuran objek ukur. Hasil inspeksi toleransi profil garis pada sudu Primary Air Fan menunjukkan bahwa pada setiap section dinyatakan tidak lolos inspeksi.

Abstract

New technology related to geometry inspection instruments that have the characteristics of good accuracy, speed, and flexibility are done on Coordinate Measuring Machine. The use of a laser scanner as a measuring instrument has the advantage of the speed of acquisition so that it is suitable for inspecting components that have a complex surface. In this study, the profile measurement method in the Primary Air Fan rotor blade component which was classified as one of the turbo engines was examined. The focus of this research is the description of the tolerance inspection process line profile in general turbo engine blades, specifically the Primary Air Fan blade of the 660 MW Steam Power Plant with refer to the ISO TR 5460 using a 3D laser scanner measuring instrument. ISO TR 5460 is a technical report standard that contains guidelines for verifying geometry tolerance that are described at ISO 1101. The process of inspection of line profile geometry on turbo engine blades with 3D laser scanner measuring instruments generally works by comparing the reference data with measured data. Reference data is a CAD model while measured data is point clouds that have been carried out triangulation / meshing process obtained from the measurement results of measuring objects. The results of the inspection of the line profile tolerance on the Primary Air Fan blade indicate that in each section it was declared not passed the inspection.
