| Summary: | MSC Nastran Patran technique was used to simulate and analysis for the
turbocharger turbine blade failure investigation. The Finite Element Method (FEM) is
applied and used for the turbine blade simulation for identifies the failure region and
point by the stress distribution. The Finite Element Method (FEM) findings and results
are a major consideration in design. Furthermore, the loads, boundary condition and
material properties are defined. The Finite Element Model is submitted for the structural
analysis once is completed. The similar turbine blade simulations from the literature
study are referred and study in order to achieve the objectives of the Projek Sarjana
Muda (PSM). The simulation results revealed that the stress distribution on the turbine
under the various case such as comparison of dimension which is 80 mm, 100 mm
(original dimension) and 120 mm and materials, Inconel X-750, Inconel 718 (original
material), Inconel 650 and Inconel 620. Meanwhile, the result verified that Inconel 718
with 80 mm turbine blade provided higher Young’s Modulus and stiffness characteristic
in the project. Inconel 718 is well representative material for turbine blade due to the
ability of withstands high pressure and temperature and insures the long wear life. Thus,
the Inconel 718 and 80 mm dimension blade is applied in the overall simulation. The
simulation result is indicated that the blade root is withstanding highest pressure which
is showed the good agreement with the realistic turbine blade failure. The MSC
Nastran/Patran is powerful method used to identify the critical areas at the turbine blade
where the weakness point appear base on stress distribution result and essential to the
marine industrial. |
