Applications of thin-walled tubular structures has been widely used in design konfigurations of automotive technology as energy absorbers when the collision occurred. One of the automotive engineering developments is a car bumper system. Car attached is to protect part of passenger compartment from frontal collision. This bumper system will absorb the impact energy of collision through deformation process (progressive buckling). With the deformation process, bumper system can lessen damage at passenger and gives deceleration residing in at safety level to passenger body. <br /> <br /> <br /> <br /> <br /> This final project will explain about analysis of thin-walled cylindrical PVC tubes undergoing quasi-static axial crushing. The objective of this research is to identify the mode of deformation and characterictics of crushing force of cylindrical PVC tubes undergoing quasi-static axial crushing. It is studied as an alternative material using polymer for energy absorbing system on the car bumper systems. <br /> <br /> <br /> <br /> <br /> The analysis has been conducted by experiment and numerical method. Numerical simulation were performed by finite element method perangkat lunak non-linear LS-DYNA. It is shown that from experiment and numerical simulation the deformation mode for PVC is diamond and the mean crushing force of experimental result higher than numerical simulation varied from 19-25%.
