Abstract

Penggunaan motor diesel truk ke dalam dunia marine masih sering terjadi, dan menimbulkan problematika di dunia marine itu sendiri. Untuk mengurangi hal tersebut, Laboratorium Marine Power Plant bermaksud mendesain motor diesel untuk mengatasi hal tersebut dengan metode reverse engineering. Salah satu komponen motor diesel yang akan di desain ulang adalah crankshaft. Selain proses redesign, pada crankshaft hasil redesain juga akan dianalisa kekuatan materialnya dalam menerima gaya akibat dari proses pembakaran di ruang bakar. Di dalam menganalisa tegangan pada crankshaft, akan digunakan jenis material antara lain 34CrNiMo6, EN-GJS-600-3, EN-GJS-700-2. Analisa dilakukan terhadap komponen crankshaft yang menerima gaya terbesar yaitu crankpin. Gaya terbesar yang dialami crankpin adalah akibat dari tekanan pembakaran yaitu sebesar 105,35 kN. Dari hasil analisa di dapat nilai tegangan yang terjadi adalah sebesar 137,22 N/mm2 untuk material crankshaft 34CrNiMo6, 138,311 N/mm2 untuk crankshaft dengan material EN-GJS-600-3 dan 138,312 N/mm2 untuk material EN-GJS-700-2. ===================================================================================================== The use of diesel truck into the marine is often becomes problems. To reduce it, Laboratory of Marine Power Plant intends to design a marine diesel engine to overcome this problems by reverse engineering methods. Crankshaft is one of diesel engine components that need to redesign. After redesign, the crankshaft will also be analyzed in receiving the material strength of the force due to the combustion process in the combustion chamber. Crankshaft analyzed with material 34CrNiMo6, EN-GJS-600-3, EN-GJS-700-2. Analysis conducted to the part of crankshaft that receive highest force, it is crankpin. The highest force is 105,35 kN, that values is product of combustion pressure. From analyzed, the stress value are 137,22 N/mm2 for crankshaft with material 34CrNiMo6, 138,311 N/mm2 for crankshaft with material EN-GJS-600-3 and 138,312 N/mm2 for crankshaft with material EN-GJS-700-2.
