Abstract

Reverse engineering adalah salah satu metode dalam mendesain motor diesel, dimana motor diesel yang sudah ada digunakan sebagai referensi dalam membuat desain. Ruang bakar pada motor diesel menghasilkan tekanan dan temperatur tinggi yang dapat menyebabkan tegangan pada silinder head. Kerusakan fatal pada silinder head dapat terjadi karena tegangan yang terlalu besar. Maka dari itu, diperlukan analisa distribusi tegangan yang disebabkan oleh tekanan dan temperatur dari ruang bakar pada hasil desain silinder head. Pada penelitian ini dilakukan analisa tegangan mekanik, thermal, dan total (mekanik-thermal) dengan menggunakan Finite Element Method (FEA) serta pemilihan material, hingga diperoleh hasil desain silinder head yang optimum. ================================================================================== Reverse engineering is one of the methods to design the diesel engines, for instance the existing diesel engine is used as a reference to design the cylinder head. The combustion chamber of diesel engine produce high pressure and high temperature which can cause stress on the cylinder head. The worst damage is able to be occurred if the stress in cylinder head is very high. Because of that reason a research of stress distribution in cylinder head design caused by combustion chamber pressure and temperature is very important. In this research is analized about mechanical stress, thermal stress, and total stress (mechanics-thermal) using Finite Element Method (FEM) and materials selection. As the results of the research is found the optimum design of the cylinder head.
