Viano 1989

These are simulation setups designed to replicate the impactor tests carried out by David C. Viano in (1989). The full reference is provided at end of this document.

PMHS reference data overview

There are variants of the hub setups, which are documented by Viano 1989. The setups differ in terms of impact speed, location and angle. The table below provides an overview of the test.

Impact Location Midpoint of Impactor aligned with Impact angle LS MS HS
Thoracic Impact Xiphoid process (XP) 330° 4.4 6.5 -
Abdmoninal Impact 7.5 cm below XP 330° 5.8 6.8 -
Hip Impact Greater trochanter 270° 5.2 - 9.8

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

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) in an appropriate time frequency!

A detailed guide with illustrations is provided in Documentation.pdf. The general procedure is outlined briefly below:

1) Put the main HBM file in the folder directory "_HBM". 2) Set the main HBM file in the I N C L U D E S section under "Include HBM main file". 3) Open the main HBM file in a pre-processor and proceed with STEP 1. 4) When STEP 1 to STEP 4 are finished, save and open the 00_Master_Hub.k file in a pre-processor and continue with STEP 5.
