Typical structural members in the automotive body have complex geometrical shapes and no standard size. Thus, generating crash behavior database for all possible dimensions of even single shape is an extremely expensive task. A remedy is to generate databases containing relatively few sizes of the structural members, then employ different methods to approximate the behavior of the structural members over the complete design domain of the dimensions. This paper simulates the behavior of the CNG tank and structural members to crash conditions by using Finite Element Method. According to standard ISO15500, these conditions are acceleration with: i)± 20g longitudinal direction, ii) ± 8g side direction and iii) 4.5g vertical direction . Then, experimental tests were done to validate theoretical results.
