Abstract: A general purpose lumped-mass simulation program CAL30 was used to simulate the belted occupant response in a 30 mph (48 kph) barrier impact environment. The occupant is represented by 14 segments connected by joints, springs and dampers based on the standard Hybrid III test dummy structure. Algorithms were developed in the CAL3D code to model the 3-point belt restraint characteristics including anchor deformation and belt slip along the beltline direction. The compliance of each belt component was obtained by conducting an MVSS 210 test with additional instrumentation. The simulation results correlated well with the barrier test data. This model can be used to evaluate various belt design concepts in the early design stage.
