Abstract
Free piston engine memiliki kekurangan akibat
terjadinya moment angular. Terjadinya moment angular
menyebabkan misfire pada mesin. Semi free piston adalah
inovasi desain mesin yang dapat mengeliminasi moment
angular dengan mengaplikasikan keyways pada connecting
rod. Analisa dalam penelitian ini meliputi tegangan mekanik,
thermal, dan thermo mekanik piston. Serta dilakukan analisa
tegangan distribusi mekanik yang diterima oleh connecting
rod. Hasil dari tegangan termo mekanik maksimal piston
terjadi pada material Alumunium A 4032 senilai 259.27 MPa.
Tegangan mekanik connecting rod maksimal terjadi pada
material C-70 dengan menggunakan material piston
Alumunium A 4032 senilai 92.35 MPa. Hasil analisa
tegangan termo mekanik piston material AL GHS 1300
memiliki pertimbangan yang terbaik untuk digunakan pada
pemilihan material piston. Berdasarkan tegangan mekanik
connecting rod material C-70 memiliki pertimbangan terbaik
untuk digunakan pada pemilihan material connecting rod.
=======================================================================================================
Free piston engines have disadvantage due to the
angular moment. The angular moment cause misfire in the
engine. Semi Free Piston is the innovation engine design that
could eliminates the angular moment by applying keyways on
connecting rod. Analysis in this research includes mechanical
stress, thermal stress and thermo mechanical stress of piston.
Analyzed also conducted to mechanical stress distribution
received on connecting rod. Maximum thermo mechanical
stress of piston occurred was used material Alumuium A 4032
value 259.27 MPa. Maximum mechanical stress of connecting
rod was used material C-70 and piston material Alumunium A
4032 value 92.35 MPa. Results thermo mechanical stress
analysis of piston material AL GHS 1300 have a greatest
consideration for selected material piston. Based on
mechanical stress distribution analysis connecting rod
material C-70 have greatest consideration for selected
material connecting rod.
