In today’s global economy, the automotive design engineer’s responsibilities are made more complex by the differences between regulatory requirements of the various global markets. This paper compares instrument panel head impact requirements of FMVSS 201 with its European counterparts, ECE 21. The behavior during a head impact test has been studied. Due to the gravity of the cockpit module, the sag has been analyzed to simulate shipping, loading, and assembly conditions. The interior parts of the vehicle cabin are exposed to temperature variations due to radiation effect of sun ray or freezing temperature in winter. Plastic parts appear to be more thermally susceptible than steel parts in temperature variations. The key issue was minimizing thermal deformation while developing the IP. The cockpit design engineers have gained an understanding of the factors involved in ensuring that their design fully meets the requirements of the subject regulations. CAE simulations performed which are repetitive processes and a unified FE modeling approach has handled analyses by different codes.
