cumulative a3ms head/chest
I use Hypergraph to evaluate my simulation results and compare them with experimental data. I carry out crash calculations and have to evaluate the load values of the dummy in order to check compliance with the limit values of the legal regulations and consumer protection. The criterion of acceleration at the chest or head is specified with the cumulative a3ms. I can apply the “NHTSA clip” value to my curve via “Injury”. However, this is the continuous acceleration value over 3ms and not the cumulative, as required by the legislation (FMVSS 213, UN-ECE R129). The acceleration over 3 ms is determined by a single peak in the continuous a3ms. With the cumulative a3ms, peaks are taken into account which together reach a total duration of 3 ms. How can I calculate the cumulative a3ms in Hypergraph?
