Analysis of the spinal 3D motion of post-mortem human surrogates in nearside oblique impacts
Piqueras Lorente, Ana; Pipkorn, Bengt; Iraeus, Johan; Lorente Corellano, Ana I.; Juste Lorente, Oscar; Maza Frechín, Mario Vicente; López Valdés, Francisco José (2023-01-02)Objective: The objective of this study is to analyse the 6 degrees of freedom (DOF) motion of the spine using the finite helical axis (FHA) in three post-mortem human surrogates (PMHS) sled tests. Methods: The sled test ... -
Effects of including a penetration test in motorcyclist helmet standards: influence on helmet stiffness and impact performance
Juste Lorente, Oscar; Maza Frechín, Mario Vicente; Piqueras Lorente, Ana; Lorente Corellano, Ana I.; López Valdés, Francisco José (2022-03-01)Regulation ECE-22.0506 does not require a helmet penetration test. Penetration testing is controversial since it has been shown that it may cause the helmet to behave in a non-desirable stiff way in real-world crashes. ... -
Kinematic assessment of subject personification of human body models (THUMS)
Piqueras Lorente, Ana; Iraeus, Johan; Lorente Corellano, Ana I.; López Valdés, Francisco José; Juste Lorente, Oscar; Maza Frechín, Mario Vicente; Pipkorn, BengtThe goal of this study was to quantify the effect of improving the geometry of a human body model on the accuracy of the predicted kinematics for 4 post?mortem human subject sled tests. Three modifications to the computational ... -
Kinematics and dynamic responses of young and elderly occupants in low-speed frontal tests
López Valdés, Francisco José; Juste Lorente, Oscar; Lorente Corellano, Ana I.; Piqueras Lorente, Ana; Danauskiené, Asta; Muehlbauer, Julia; Symeonidis, Ioannis; Maza Frechín, Mario Vicente; Peldschus, Steffen; Schick, SylviaObjetive: The objective of the study was to compare the kinematics of young and elderly volunteers in low-speed frontal impacts to identify the existing differences in the motion of the head and upper spine. Method: Five ... -
The influence of headformhelmet friction on head impact biomechanics in oblique impacts at different tangential velocities
Juste Lorente, Oscar; Maza Frechín, Mario Vicente; Piccand, Mathieu; López Valdés, Francisco José (2021-12-01)Oblique impacts of the helmet against the ground are the most frequent scenarios in real-world motorcycle crashes. The combination of two factors that largely affect the results of oblique impact tests are discussed in ...
