   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Ester Pörtfors; Malin Svärdling; [2024]
   Keywords : Mechanical CPR; Cardiopulmonary Resuscitation; LUCAS Chest Compression System; Test Equipment; Chest Biomechanics; Chest Stiffness; Technology and Engineering;

   Abstract : The LUCAS Chest Compression System is a market leading mechanical cardiopulmonary resuscitation device, assisting medical professionals worldwide when treating patients with sudden cardiac arrest. The objective of this master thesis project was to develop a new, adjustable test equipment for the LUCAS device, allowing for tests on varying chest heights and stiffness levels. READ MORE

3. 2. CAE modelling of cast aluminium in automotive structures

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Subrat Singh; Sreehari Veditherakal Shreedhara; [2019]
   Keywords : Material failure model; LS- Dyna; Non-linear Finite Element analysis; Cast aluminium; Explicit FEA; LS-DYNA; Drop tower; Spring tower; Strut Tower; FEM; CrachFEM; ANSA;

   Abstract : In the automobile industry, there is a big push for the automotive car manufacturers to base engineering decisions on the results of Computer Aided Engineering (CAE) solutions, and to transform the prototyping and testing, from a costly iterative process to a final verification and validation step. The variability in components material properties and environmental conditions together with the lack of knowledge about the underlying physics of complex systems often make it impractical to make reliable predictions based on only deterministic CAE models.

4. 3. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Simon Stahlin; [2019]
   Keywords : composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

   Abstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

5. 4. Advanced bushing script program in MSC ADAMS

   University essay from KTH/Fordonsdynamik

   Author : Rahul Gowthaman; Suhail Jagwani; [2018]
   Keywords : MSC ADAMS Car; rubber bushing; Computer Aided Engineering; stiness; measured data; force hysteresis; dynamic loading;

   Abstract : The thesis focuses on investigating and optimizing a bushing script implemented as a tool in MSC ADAMS/Car. The study provides an insight on the representation of a rubber bushing and identify parameters which can be used to define the properties of a bushing in a simulation environment such as ADAMS/Car.
