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.
