The Insurance Institute for Highway Safety (IIHS) Small Overlap Frontal (SOF) impact assessment program is one of the latest challenges for the automotive development. The SOF load bypasses the primary crumple zone structure and concentrating the force in the front wheel, suspension and firewall - areas not traditionally designed to absorb and dissipate crash energy. Design changes of architectural components at later stages of product development is very difficult and expensive. This paper deals with the procedure to improve SOF performance through CAE as well as to develop the physical test cart to avoid the full vehicle SOF test. CAE procedure developed on chassis subsystem level to validate the SOF performance of front suspension. Using this procedure, design changes in the suspension components to improve the SOF performance can be done by keeping the suspension durability and other performance requirements as intact.
