1. State-of-the-art DC Current Interruption Concept using SiCMOSFETs
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The transportation is in transition to the electrification era where the main source of energy for thevehicles is supplied by high energy propulsion batteries with voltages above 400 V. Currently the majority of the batteries are lithium-ion batteries and it is crucial to protect them from shortcircuits in order to ensure the safe operation in case of a vehicle crash or misuse of the vehicle.

2. Design and Crash Analysis of Ladder Chassis
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : A chassis is known as the carrying unit of an automobile, like the engine, transmission shaft and other parts are mounted on it. Ladder chassis has longitudinal rails which are connected along the length with crossmembers through welding or mechanical fasteners. Rectangular box section is chosen for the longitudinal rails of ladder chassis. LÄS MER
3. Theoretical experiment of GISSMO failure model for Advanced High Strength Steel
Magister-uppsats, Högskolan Väst/Avdelningen för produktionssystem (PS)Sammanfattning : When developing an electric vehicle, it is essential to evaluate the deformation in and around the battery box for different crash scenarios, and it is necessary to develop a more advanced model that would take into account all the stress modes. Thanks to the excellent properties of Advanced High Strength Steel (AHSS) combine with high strength for more safety and weight reduction for less exhaust emission, AHSS is more and more commonly used in automobile industry.

4. A finite element study of shell and solid element performance in crash-box simulations
Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för maskinteknik och naturvetenskapSammanfattning : This thesis comprehends a series of nonlinear numerical studies with the finite element software's LS-Dyna and Impetus AFEA. The main focus lies on a comparative crash analysis of an aluminium beam profile which the company Sapa technology has used during their crash analysis. LÄS MER
5. Origami Pattern Tube for Vehicle Crash Box
Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskapSammanfattning : With an increasing number of traffic accidents, more and more people are injuring or even dying during the collision. One of the main reasons is frontal collisions. Therefore, the safety system is a very important part of the vehicle. LÄS MER
