  4. 2. Simulation methods for bumper system development

    Author : Erik Isaksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : n development of bumper systems for the automotive industry, iterative Finite Element (FE) simulations are normally used to find a bumper design that meets the requirements of crash performance. The crash performance of a bumper system is normally verified by results from standardized low speed crash tests based on common crash situations. READ MORE

  5. 3. A Study of an Integrated Safety System for the Protection of Adult Pedestrians from Car Collisions

    Author : Sunan Huang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remote Sensor System; Reversible Hood; Traffic Accidents; Contact Sensor; Pedestrian Protection; Reversible Bumper;

    Abstract : This study aimed to evaluate and improve the performance of a newly developed safety system intended to protect pedestrians during frontal car collisions. This system includes a remote sensor system, a contact sensor, a reversible bumper system (RBS), and a reversible hood (RH). READ MORE

  6. 4. Microfluidic Preparation and Transport of Long DNA using Pillar Arrays

    Author : Oskar Ström; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microfluidics; Deterministic Lateral Displacement; DNA Separation; Elastic Turbulence; Micro-pillar arrays; DNA Sample Preparation; Lab-on-a chip; elastic waves; Sample Preparation; DNA Isolation; bumper array; Fysicumarkivet A:2023:Ström;

    Abstract : This thesis presents a set of microfluidic tools and experimental studies for preparing (> 20 kbp) for genetic analysisas well as the transport of high-concentration, long-DNA solutions in pillar arrays.Long-DNA sample preparation with conventional gel-based techniques is slow (tens of hours to days) and laborious.

  7. 5. Analysis of Sensing Systems for the Detection of Pedestrian Impacts

    Author : Sunan Huang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing system; pedestrian safety; accident investigation; statistical simulation; contact sensor; FE simulation;

    Abstract : In order to reduce pedestrian casualties in vehicle traffic accidents, safety countermeasures, for example the active hood system and external airbag system, have been proposed to protect pedestrians in vehicle collisions. Such a protection system must consist of a sensing system to detect the pedestrian impact and/or the potential impact. READ MORE
