Safety belts play a very important role in restraining the occupants in a collision, thereby reducing occupant injuries/ fatalities. Strength of the safety belt anchorages are being evaluated by the passenger car manufacturers as per ECE R14/FMVSS 210. Since 2002, evaluations of safety belt anchorages have become mandatory in India. With increasing pressure to cut the design cycle time, manufacturers are focused on Computer Aided Engineering (CAE) for faster design and validation. The results of a CAE simulation largely depends on the user input and model accuracy. Hence a need arises for establishing a credible correlation between the laboratory test results and the CAE simulation results. This paper discusses such a correlation exercise carried out for safety belt anchorage testing through anchorage deformation mapping (ADM) and floor deformation mapping (FDM).

Side impact collisions are one of the most frequently occurring road accidents leading to occupant injury and even death. To provide better safety to occupants during such collisions, side doors and side body structures in modern passenger cars have been designed to absorb the impact energy and reduce the depth of intrusion into the passenger compartment. Side impact performance components are often evaluated by conducting a dynamic full vehicle crash test and a quasi-static side door intrusion test. The Indian regulation for side impact performance evaluation comprises of the quasi-static side door intrusion test. This paper highlights the variation in crush strength performance viz., initial crush resistance, intermediate crush resistance and peak crush resistance, due to the difference in the rate of load application as per IS12009:1995.
