Abstract

Tractors are important vehicles for agricultural fields and they are widely
used. Even if they do not be in the traffic due to their intended use, safety
of the driver is important if the tractor is rollover. In tractor, the impact
energy is provided by cabin or protective profile structure during rollover.
Safety test conditions have been established by Organization for Economic
Co-operation and Development (OECD) by determining the loads that may occur in
case of rollover. According to the standard which developed by OECD, the
effects of the energy to be generated during rollover or impact on the
structure are examined by performing tests under the specified loads. In this
study, static loading test of tractor cabins is simulated by finite element method
according to the ISO 3471 standart. Tractor cabin finite element models have
been prepared with HyperMesh and HyperCrash software. Nonlinear explicit
analysis of the model was performed under the loads applied during the test. .
The analysis were carried out using RADIOSS software, based on the operating
principle of the load carrying mechanism in order to simulate the test loads. The
finite element model is limited to the frame connection points and the
deformations are examined for three loading conditions. According to the
results which are obtained from the test, the finite element analysis of the
designed cabin was also validated.
