Bouquet et. al 1994

These are simulation setups designed to replicate the hub impact on the thorax and carried out by Bouquet et al. (1994). The full reference is provided at the end of this document.

PMHS reference data overview

There are variants of the hub setups, which are documented by Bouquet et. al (1994). The setups differ in terms of impact speed and location. The table below provides an overview of the test.

MRT 02	MRB 03	R.Pelvis	3.40	Middle sized male
MRT 02	MRB 04	R.Pelvis	6.50
MRT 03	MRB 05	R.Pelvis	3.41	Middle sized male
MRT 03	MRB 06	R.Pelvis	6.77
MRT 04	MRB 07	R.Pelvis	3.43	Small sized male
MRT 04	MRB 08	R.Pelvis	6.46
MRT 05	MRB 09	R.Pelvis	3.29	Small sized male
MRT 05	MRB 10	R.Pelvis	6.??
MRT 06	MRB 11	R.Pelvis	3.34	Large sized male
MRT 06	MRB 12	R.Pelvis	6.64
MRT 07	MRB 13	R.Pelvis	3.35	Middle sized male
MRT 07	MRB 14	R.Pelvis	6.44

The characteristics of all PMHS used in these tests are provided in the table below.

Subject Number	Weight (kg)	Height (m)	Age
MRT 01	82	1.73	76
MRT 02	76	1.74	57
MRT 03	69	1.73	66
MRT 04	52	1.64	69
MRT 05	54	1.62	69
MRT 06	86	1.81	38
MRT 07	60	1.70	63
Average	68.4	1.70	62.6

Instructions

Follow the General Instructions for setting up your simulations. Make sure that all required outputs are available in the simulation output files (e.g. binout when using LS-Dyna) in an appropriate time frequency!

A detailed guide with illustrations is provided in the Documentation_Hub_Sternum.pdf and the Documentation_Hub_Pelvis.pdf.

Please report all new issues you encounter.
