1. 1. Transverse force absorption in column base mounts for steel columns : Screw joints in column bases

   University essay from KTH/Byggteknik och design

   Author : Dejan Jovanovic; Ruslan Khalilov; [2021]
   Keywords : column bases; transverse force absorption; tightening moment; clamping force; non-prestressed joints; Pelarfötter; tvärkraftskapacitet; åtdragningsmoment; spännkraft; icke förspända förband;

   Abstract : It is common to use different construction materials in combination such as concrete, steel, wood and glass in order to optimize buildings. The purpose of this is to reduce weight and increase load capacity, but it also facilitates assembly and reduces construction time. READ MORE

3. 2. Methods to create compressive stress in high strength steel components

   University essay from

   Author : Amir Abdin; Kaveh Feyzabi; Oskar Hellman; Henrietta Nordström; Dilman Rasa; Gustav Thaung Tolförs; Per-Olof Öqvist; [2018]
   Keywords : residual compressive stress; high strength steel; methods of inducing stress; analyzing stress;

   Abstract : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.

4. 3. Strengthening of I-girder bridges : Fatigue endurance

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

   Author : Olle Edström; [2016]
   Keywords : ;

   Abstract : Structures have always been subjected to the detrimental consequences of the fatigue phenomenon. The consequences due to this damaging effects leads to crack initiation and the ultimate result being complete failure. Fatigue appears on structures that has to endure fluctuating loads over a long period. READ MORE

5. 4. Optimal Vehicle Speed Control Using a Model Predictive Controller for an Overactuated Vehicle

   University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

   Author : Mathias Mattsson; Rasmus Mehler; [2015]
   Keywords : MPC; Overactuated; Control Allocation; Vehicle Dynamics; Speed Control;

   Abstract : To control the speed of an overactuated vehicle there may be many possible ways to use the actuators of the car achieving the same outcome. The actuators in an ordinary car is a combustion engine and a friction brake. In some cases it is trivial how to coordinate actuators for the optimal result, but in many cases it is not. READ MORE

6. 5. Steering System Modelling for Heavy Duty Vehicles

   University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

   Author : Rickard Sjölund; Nicklas Vedin; [2015]
   Keywords : Advanced Driver Assistance System; Steering System; Lane Keep Assist; Power Steering Gear; Physical Modelling; Hydraulic Power Assist; Bond Graph;

   Abstract : Future heavy duty vehicles will be designed and manufactured with improved Advanced Driver Assistance Systems, ADAS. When developing ADAS, an accurate model of the vehicle dynamics greatly simplifies the development process. One element integral to the vehicle lateral dynamics and development of ADAS is the steering system. READ MORE
