ANALISA UJI PENDULUM PADA STRUKTUR RANGKA BUS DENGAN MENGGUNAKAN FINITE ELEMENT METHOD (FEM)

Abstract

A bus is one kind of vehicle that can carry a lot of passengers. That the reason why a bus must be designed well to give a secure feeling to the passengers and also to the driver and the crew. A bus framework structure is a part of a bus whose function is as a coach for the vehicle. In many cases of accident, the strength of framework structure has big affect to the safety of the passengers. One of the accident is the rollover accident, which can injured or even kill a passenger inside the bus. In Europe the rollover accidents of bus has been addressed by the regulation ECE R66. In this final project will be analyzed about the displacement and safety on bus framework structure (HINO, RK8JSKA-MHJ type) by giving a pendulum load according to ECE R66. The author do the analysis using finite element method and the ANSYS/LS-DYNA as supporting software. The result of the analysis shows that the displacement and the concentration of the stress only happen on side part joint of the bus framework structure. The amount of displacement on this part do not surpass the residual space, thus the bus framework structure is save if it is hit by pendulum load or rollover load.
