Hybrid III 50th v.8 Official Release

June 14, 2013 - Humanetics is happy to announce the release of the Hybrid-III 50th percentile male dummy model v8.0 for both PAM-CRASH and LS-DYNA codes. These models represents a large leap forward in both the geometric representation of the dummy and the material characterization used to develop the material models. An entirely new mesh has been created for these models, which is based on the latest available CAD and scan data.
 
Many component and sub-assembly level validation cases were performed on the model to assess the response of the model in a wide variety of loading conditions at varying levels of complexity. In all certification validation cases, the model has been compared to test cases extracted from a large set of data performed by the Humanetics test labs (a total of 754 individual tests). This data was analyzed to find results that statistically represent the average test response. The areas of focus during the development of this model were the neck and chest responses. New material testing (covering wide range of strain and strain rates) and material modeling techniques led to significant improvements. For example thorax validation shows improvement both in the chest deflection and force-deflection characteristics across a wide range of loading conditions. [See image below for low speed pendulum certification chest response].
 
 
 
In the neck, the joint stiffness curve used to model the nodding blocks has been replaced with a physical representation of the nodding block with appropriate material properties, and contact defined within the model to better match the physical dummy. Additional non-certification tests were carried out with the neck rubber to improve the neck in less complicated load cases. This has led to a more physical response in the neck, both in certification test and full dummy sled validation tests.
 
In addition to the component and sub-assembly validation cases, full dummy sled validation cases were carried out. The CORA rating was used to compare the model to the test data in order to more objectively asses the performance of the model to that of the physical hardware. Solid improvements were found with dummy signal ratings, improving on a scale from 0 to 1 (with higher ratings corresponding to better correlation) from 0.85 to 0.92, in the PAM-CRASH model and 0.87 to 0.92, in the LS-DYNA model in the sled case with a modern restraint system. In the simpler sled case, with fixed belts and a simplified knee bolster, the models improved from 0.80 to 0.89 In PAM-CRASH and 0.87 to 0.89 in LS-DYNA.
For the new LS-DYNA release, a new encryption protocol will be used, all models will be encrypted prior to release from Humanetics to prevent unauthorized usage. Models now become non-viable after the expiration date.
