abstract="The importance of a vehicle sub-frame is often discussed in vehicle compatibility. To observe how the sub-frame geometry influences the vehicle response, three different sub-frame configurations were modeled and simulated in US NCAP crash test configurations as well as car-car simulations. The former simulations were used to observe how the design changes would influence self protection in a crash test influencing the original design of the vehicle. The latter simulations were to observe how the modification would influence vehicle compatibility under &quot;real world&quot; conditions. The rigid barrier impacts could detect the changes in the design. The most forward placement of the sub-frame had a stiffer response than the other configurations as observed in acceleration pulse and barrier wall loads. Self protection also tended to be improved over the baseline configuration. In car-car testing, it was difficult to identify a clear subframe configuration that provided improved compatibility. Both the standard and forward placed subframe had better performance than the most rearward configuration. Neither the baseline nor extended sub-frame versions were clearly better for all car-car impact configurations but an extended sub-frame exhibited better self protection, especially when the vehicle was lower than its collision partner.
