Abstract

The purpose of this paper is to compare the biofidelity of LSTC and TRL legform impactor. A finite element model of simplified front vehicle structure was established. The simulation tests were conducted by using this simplified car model against two different legform impactors and a FE lower extremity, respectively at a speed of 40km/h. The simulation results from the two legform impactors were compare with that of the FE lower extremity. The compared outputs include tibia acceleration, shear displacement, knee bending angle. The test results show that the tibia acceleration of the impactors and the FE lower extremity are approximately consistent. As to the shear displacement and the knee bending angle, though the output of the impactors are not agreed so well with that of the FE lower extremity, the trend are comparable to some extent. The results of the FE lower extremity are higher than that of the legform impactors. The results of LSTC impactor has a better agreement with that from FE lower extremity.
