MATCHING AND STITCHING FOR SURFACE IDENTIFICATION Jamari, Jamari
ROTASI Volume 8, Nomor 4, Oktober 2006
Publisher : Departemen Teknik Mesin, Fakultas Teknik, Universitas Diponegoro

An algorithm to determine changes in surface topography on asperity level has been developed in this paper. The software tool stitches small but detailed images together to create one large image. If such an image is made before and after an experiment, their difference shows a direct 3D view of the changes in micro-geometry, rather than a change in surface parameters such as RMS or CLA roughness. The algorithm is described in detail and demonstrated by appling to real rough surfaces.

Salah satu indikasi kerusakan komponen mekanik adalah keausan. Keausan disebabkan oleh berbagai macam faktor diantaranya adalah jenis material yang berkontak, kondisi pelumasan, perlakuan terhadap pengoperasian komponen, kekasaran permukaan yang berkontak, kondisi operasi dan lain-lain. Seringkali keausan menyebabkan kegagalan, namun demikian, keausan akibat proses running-in justru menguntungkan. Running-in merupakan proses adaptasi antar komponen yang berkontak menuju keadaan setimbang, sehingga proses ini sangat menentukan sistem kontak sesudahnya. Makalah ini bertujuan mempelajari fenomena keausan running-in pada kontak sliding antara bola baja dengan pelat kuningan melalui pengujian dengan mesin jenis two-disc. Sliding dilakukan dengan slip 200% yaitu menahan salah satu disc dan memutar disc pasangannya. Fenomena running-in dipelajari melalui perubahan koefisien gesekan dan perubahan topografi permukaan yang berkontak. Hal yang menarik adalah pengukuran koefisien gesekan dan topografi permukaan dilakukan semi-online. Kurva koefisien gesekan sebagai fungsi dari waktu ditampilkan dan perubahan topografi permukaan kontak selama proses atau running juga ditampilkan pada setiap siklus atau waktu tertentu. Periode running-in dapat diprediksi melalui perubahan koefisien gesekan dan dikonfirmasi dengan perubahan kekasaran permukaan.

ROTASI Volume 10, Nomor 1, Januari 2008
Publisher : Departemen Teknik Mesin, Fakultas Teknik, Universitas Diponegoro

Study the change of the surface topography using spectral density analysis was done by performing experiments on ball-on-plate steel under boundary lubricated reciprocating sliding contact. Measurement of the surface topography was executed by an optical profilometer: Micromap 512. Matching and Stitching computer code method was employed in order to get more detailed information about the surfaces before and after the experiment. The profile evolutions of the surface for a certain number of running cycles were presented on the PSD (Power Spectral Density) and spatial frequency form. In the analysis, results show that the surface changes more in the running direction than in the traverse direction.

Komponen mesin yang saling berkontak dan terjadi gerak translasi satu sama lain disebut sebagai kontak sliding atau kontak luncur. Gerakan sliding paling banyak dijumpai pada proses manufaktur maupun proses lainnya seperti grinding, gerakan ring-piston dan lain-lain. Makalah ini mempresentasikan pemodelan elemen hingga kontak sliding baik yang tunggal maupun berulang pada sistem kontak antara bola dengan permukaan kasar. Pemodelan dilakukan melalui beberapa tahap: pengukuran geometri permukaan, proses pemberian geometri permukaan kasar hingga proses analisa elemen hingga. Parameter-parameter kontak sliding ditampilkan melalui distribusi tegangan von Mises dan perubahan topografi permukaan kasar baik untuk kontak sliding tunggal maupun berulang. Model yang dikembangkan telah berhasil mempresentasikan fenomena kontak sliding terutama pada perubahan topografi permukaan kasar.

Material UHMWPE (Ultra High Molecular Weight Polyethylene) sering digunakan sebagai actebular liner pada sistem sambungan tulang panggul buatan. Fungsi material ini sebagai bantalan dan peredam. Performansi material ini terus dikaji dan ditingkatkan melalui berbagai macam teknologi. Optimasi bentuk tekstur merupakan salah satu cara dalam meningkatkan karakteristik tribologi. Paper ini bertujuan mengkaji pengaruh tekstur permukaan terhadap distribusi Â tegangan Â vonÂ Mises Â untuk Â beban Â statik, roling dan sliding. Perhitungan tegangan dan distribusinya dilakukan mengunakan metode elemen hingga. Hasil menunjukkan bahwa untuk semua kasus pembebanan baik statik, roling maupun sliding tegangan von Mises yang terbesar terjadi pada tekstur permukaan yang memiliki diameter lubang (cavities) yang terkecil. Selain itu besarnya tegangan maksimum von Mises paling besar terjadi pada kasus beban kontak sliding kemudian kontak roling dan yang paling kecil kontak statik.
