ANALISA KEKUATAN SUPER STRUKTUR BUS AKIBAT KECELAKAAN TERGULING (ROLLOVER) DENGAN MENGGUNAKAN UJI PENDULUM
Abstract: Rollover accidents
are critical issue in many countries in the world because it is one mode that
often causing the number of deaths and serious injuries to passengers and crews
bus. Therefore, to ensure the safety of passengers necessary to test the
strength of the bus superstructure prototype before the bus have road worthy
license. Testing is guided by the standards that apply to a state. One of the
standards used at many countries in the word is ECE-R66 (Economic Commission for
Europe-Regulation 66) which regulates the construction and design of many types
of passenger vehicles.In this research, methods of testing are the pendulum
test and it was simulated by Finite element software soft ware. The purposes of
this study are evaluating compatibility this software, determining energy
absorption capacity and the deformation that occurs in the superstructure when
a loads subjected from the outside of superstructure. In the pendulum test
simulation the maximum deformation value is 520 mm at time is 0.45 s, and 466
mm at time is 1.5 s. The maximum stress occured at the joint between the roof
structure with cantrail and it’s value equal to 266 at simulation. Beside it,
the simulation show the energy is absorbed by the superstructure at rollover
test simulation equal to 66.23%.. Base on simulation result, it can be
concluded that the modeling vehicle is indicated safety for passenger if occure
rollover accident.
