Abstract

Komponen tube torsion bar pada sistem suspensi Panser Anoa 6x6 mendapat perhatian lebih untuk diteliti karena pernah ditemukan kegagalan pada komponen ini. Torsion bar yang terdiri dari shaft dan tube ini berfungsi untuk mengembalikan ban ke posisi semula setelah mengalami guncangan vertikal. Material yang digunakan pada komponen torsion bar adalah DIN 42CrMo4. Pada penelitian ini, dilakukan anilisis statis dengan metode elemen hingga menggunakan perangkat lunak Autodesk Inventor untuk mengevaluasi desain tube agar dapat mengurangi potensi kegagalan. Hasil simulasi menunjukkan bahwa distribusi tegangan tertinggi pada desain tube saat ini terletak di area spline dengan tegangan sebesar 787,7 MPa. Tegangan ini melebihi batas kekuatan yield material sehingga dilakukan optimasi geometri pada komponen. Desain tube modifikasi mampu mengurangi tegangan kritis namun belum signifikan, dimana pada desain modifikasi radius fillet tegangan tertinggi berkurang sebesar 1,2%, pada desain modifikasi diameter dalam berkurang sebesar 2,3%, dan berkurang hingga 6,16% pada desain modifikasi kombinasi. ========================================================================================================= The torsion bar tube component in the suspension system of Panser Anoa 6x6 is considered to be studied further due to findings of failure at the component. A torsion bar consists of two component elements, which are shaft and tube, aimed to return the tire to its original position after experiencing vertical shocks. The material used for this torsion bar components is DIN 42CrMo4. In this study, a static analysis using finite element method with Autodesk Inventor software is conducted to evaluate the tube design in order to decrease the failure potentials. The simulation result showed the highest stress found on the current tube design is located in spline area as big as 787,7 MPa. This amount of stress exceeds the threshold of its material yield strength, so that a geometry optimization on the tube component is necessary. The modified tube designs could decrease the highest stress but not yet significant. Where in the modified design of fillet radius, the highest stress is decreased as much as 1,2%, and decreased as much as 2,3% in the modified design of inner diameter. While in the modified design of the fillet radius and inner diameter combination, the highest stress is decreased up to 6,16%.
