STUDY OF THE EFFECT OF STRAIN RATE ON THE AUTOMOBILE CRASH DYNAMIC RESPONSE

Fixed barrier impact analyses using the lumped mass method have been performed on a 1974 Pinto automobile for the purpose of assessing the effect of the rate at which structural components deform on the compartment dynamic crash response. A variety of rate functions were used and the results were compared with crash test data at 20, 30, 40, and 50 mph impact velocities. The results show that the rate function has a very significant effect on the vehicle dynamic behavior, and that great care must be exercised in selecting the appropriate rate function for simulating the automobile structural dynamic response in crash conditions.
