“…From the examination of each conditions of contact stress using numerical analysis which has been mentioned above it is clear that flange surface roughness give effect to the contact area and contact stress, Haruyama et al [6]. Haruyama et al [7] studied the real measurement result of contact width, area when surface roughness is considered and local contact stress have been examined through numerical analysis and the distribution of contact stress has been clarified. Then, the gap between result of contact area measurement through surface observation and the result of numerical analysis is proved to be small.…”

Previous studies on corrugated metal gaskets have established that the contact width, contact stress, and surface roughness are important design parameters for optimizing gasket performance. However, the contact stress and contact width considering the surface roughness when the leakage occur did not defined yet. In this study, we determined the real contact stress and contact width when leakage started on 25A-size metal gasket. The contact width determined through a comparison between simulation and experimental results. The contact stress determined through a simulation analysis. The experiment involves a helium leakage test using new metal gaskets having different surface roughness levels. The result justified that the real contact width and average contact stress when the leakage started occur were 0.195mm and 800MPa, respectively. There is a good agreement for contact width both by simulation and experiment result. The contact width for flange having surface roughness 1.5μm is longest than the others.

“…Previous research [4] also simulated contact width and contact stress on CMG based on surface roughness. The contact width between the flange and the gasket increases on the flange with lower roughness values [5]. The results showed that the high surface roughness value made it difficult to prevent leakage due to the equal material hardness between gaskets and flange.…”

“…High gasket stiffness increases contact stress but complicates the cold forming process. The hard surface of the gasket in contact with the hard surface of the flange also causes a small contact width [5]. To prevent leakage, high contact stress and large contact width are required.…”

Corrugated metal gaskets (CMG) made from SUS304 have previously been developed, however a coating process with a softer material is necessary for its design to be optimal. The coating process is time consuming and expensive. This research aims to develop CMG from aluminum by simulation analysis and form a CMG design made of aluminum A1100. The method used is development research. The optimum CMG thickness is analyzed using ANSYS Finite Element Analysis (FEA). The control variables being investigated are contact area and contact stress. The independent variable being investigated is the material thickness of CMG. An aluminum gasket is then constructed using a cold-forming process based on the optimum design. The control variables in the leak test are axial force and water pressure. Experiments were also carried out to test the aluminum gasket for leakage. A leakage test is carried out using a water pressure test. Simulation analysis showed results that were in line with experimental leak tests. FEA simulation results show that the optimum gasket thickness is between 3 and 5 mm, with 5 mm being the most optimal. However, CMG with thicknesses of 4 and 5 have similar contact stress and contact area. Leakage test results also show similarities with simulation results. CMG with a thickness of 5 mm has the best performance. The experimental results show that CMG made from aluminum A1100 is suitable for use as a gasket to prevent leakage, it prevents leakage at fluid pressure up to 12 MPa and axial force 100 kN. The results show that aluminum CMG performs on par with SUS304 CMG coated with nickel or copper. This research succeeded in developing CMG made of aluminum

“…Bahan baru ini diharapkan memiliki performa yang serupa dengan asbestos. Beberapa peneliti telah mencoba untuk meneliti bahan baru dan beberapa peneliti lain mengembangkan sistem sealing yang baru dengan mengoptimalkan beberapa parameter perancangan untuk meningkatkan sealing performance [1][2][3][4][5][6][7]. Belum ada produk ideal yang bisa menggantikan gasket berbahan asbestos sehingga bahan yang berbeda perlu dikembangkan agar sesuai dengan berbagai aplikasinya.…”

Perkembangan metode elemen hingga memberikan kemudahan bagi para peneliti untuk memprediksi proses dan hasil forming suatu produk sehingga kegagalan bisa dicegah lebih awal dan biaya karena cacat produk bisa dihindari. Pada penelitian ini, proses forming metal gasket three-layer bentuk bergelombang akan di investigasi dengan analisa simulasi yang menggunakan metode elemen hingga. Kesesuaian bentuk produk gasket dengan cetakan mempengaruhi performance gasket tersebut saat proses tightening. Dimensi cetakan gasket menggunakan cetakan gasket 400MPa-mode dengan variasi ketebalan surface layer. Base material menggunakan SUS304 dan surface layer menggunakan ratio modulus elastis 0.1 dan 0.5. Hasil simulasi menunjukkan bahwa gasket forming tidak memenuhi cetakan dan pada bagian puncak gelombang gasket terjadi lekukan. Besarnya lekukan pada puncak gelombang menurun dengan naiknya ketebalan surface layer. The development of finite element methods help the researchers to predict the process and the result of product forming so that failure can be prevented earlier and costs due to product defects can be avoided. In this study, the process of forming metal gaskets of corrugated three-layer forms will be investigated by simulation analysis using finite element method. The suitability of the shape of the gasket product with the mold affects the performance of the gasket during the tightening process. Gasket mold dimensions use 400MPa-mode gasket molds with surface layer thickness variations. Base material using SUS304 and surface layer using Aluminum. The simulation results show that the forming gasket did not fill the mold and at the peak of the gasket convex occurs indentation. The amount of indentation at the convex of the wave decreases with the increase in surface layer thickness.
