Abstract
Foreward The data provided were created for Aware2All, a project from the European Union's Horizon Europe research and innovation programme under grant agreement number 101076868. All datasets are subject to the following license: © 2024. This work is licensed under a CC BY-NC-ND 4.0 License. The data presented is intended for use in further research to address challenges in occupant protection for Highly Autonomous Vehicles (HAVs). Data extracted from DLR's Urban Modular Vehicle - PeopleMover 2+2 Finite Element model for structural and restraint system design and optimisation at 50km/h Full Frontal Rigid wall impact. The data provided has been simplified for public viewing and for Research purposes. The reader can request more information from [email protected], quoting "Aware2All" and the purpose in the request. Further information on vehicle performance, restraint system development and application can be found in Deliverable 2.3 of Aware2All under the following link: https://doi.org/10.5281/zenodo.15780974 Modified VIVA+ models for use in Highly Autonomous Vehicle seating postures can be found under the following link (LS-DYNA compatible): https://doi.org/10.5281/zenodo.14765398 Description of Content DLR-UMVPM-Aware2All_Demo1_interior_Measurements.pdf Contains measurment data of the UMV PM interior of the prototype vehicle UMVPM_Occupant_VIVA+_forward_seating_(/sideview)_Annotated Shows an example of the posture of the Occupants in forward seating arrangement with the Restraint System in place viva50F(/M)_Seat1_postureHAV.json Provides the location and joint articulation to achieve the desired posture of the VIVA+ HBM for version 2.0.1 of the VIVA+ FE-HBM. Can be applied to the metadata for marionette method posturing pre-simulation DLR_UMVPM_example_responses_XXkmh_FFRW.cur Where 'XX' signifies the vehicle speed. The '.cur' data provides example acceleration graphs up to 120ms for use in LS-DYNA. The information can be parsed into .csv "UMVPM_... .avi" Various videos highlighting stress distribution (scalar), part energies (scalar), displacement and deformation as the respective title of the file indicates. More specific information can be found in Deliverable 2.3 (link provided above) or contacting the responsible person(s). General Information of Demonstrator 1 Vehicle Crash set-up: - The vehicle underwent a Full Frontal Rigid Wall (FFRW) impact test at various velocities (30, 40 & 50km/h). The test set-up (aside from vehicle velocity changes) followed the General guidelines of the EURO-NCAP / UN-R137 test protocol. - The model was built for simulation in explicit solver LS-DYNA, versions R12.2.2 and R13.1.1. - Positioning of the Dummy was conducted through a one-stage marionette seating method (utilising DUMMY tree assemblies to define the marionette procedure and joint/assembly angles) to adopt the posture and provide seat deformation (with initial stresses) of the seat foam. The anti-submarining plate was positioned simultaneously. - Positioning of the HBM was conducted through marionette method to ascertain the posture. The HBM skin was rigidified to perform the LS-DYNA 'seatsquash' procedure. Following this, the positioned HBM was subject to a short relaxation phase prior to the transient analysis to enable convergence of contact forces and deformation of the seat and HBM.
