ONE of the most important concerns in the auto industry is the issue of safety. therefore some of the international organizations and institutes has written some crashworthiness standards for autos. Numerical simulation has been in the spot greatly by the automakers due to the enormous costs of real full scale tests. In this study the numerical simulation of European standard ECE.R29 for Benz 2624 comiunet which has been ordered by IRAN KHODRO complex, is considered. this standard contains three tests which are: (A) Front contact test, (B) Roof strength test, (C) Rear wall strength test. the steps for finite element modeling of a comiunet are: Preparing 3D drawings (by the use of CATIA, SOLIDWORKS). Fixing geometry disorders (defeats), Simplifying model geometry, Meshing the model, Defining element attributes (properties), Determining the material properties, Applying boundary conditions and forces, And finding output results. All of the steps described above are done by preprocessor software "HYPERMESH". the Ls dyna ‘s specified solver for crash is used to analyze the simulation. also for a qualitative comparison of the results, all of the tests are done for a validated model of Ford F800. the main results of tests including the deformation of the structure after any test are brought and compared. After any test there should not occur any contact between the structure of the auto and the passenger of the car, in this case, the dummy HYBRID III 50%. also the energy balance is brought for each test by some graphs. In addition, at the end of conclusion chapter, the effect of the variations in some parameters on the results is considered and analyzed.
