The RailSafe (RS) Dummy FE model, developed by GRM in 2015, aids virtual design of train tables/seats per Rail Standard GM/RT2100. This standard, created by RSSB, TRL, and DeltaRail (2002-2005), defined the Hybrid III RS rail-variant crash test dummy, modifying the automotive Hybrid III for rail use. The Simcenter Radioss FE model is a digital twin of this dummy.
The RS Dummy Simcenter Radioss model has been calibrated to several usage scenarios and is capable of representing all injury metrics.
The model includes all specific abdomen metrics, plus typical HIII injuries such as knee shear, tibia loads, tibia index, femur load, and head/neck metrics.
Qualified over numerous test cases, the RS Dummy includes methods to prevent premature model termination, improving the throughput of design development.
The flexibility of the pelvis flesh and leg interaction supports the application of this dummy to multiple scenarios beyond the train table arena.
Avoid costly physical tests by using the RS Dummy to meet train seat injury standards. It assesses abdominal load propagation, enabling optimized table positioning and deflection to protect occupants.
