  1. 1. Structural Analysis and Redesign of a L90 Front Axle Casing

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Erik Berra Widén; [2023]
    Keywords : FEM; Ansys Mechanical; Axle Casing; Volvo CE; Wheel Loader; Redesign;

    Abstract : This thesis was commissioned by Volvo Construction Equipment (Volvo CE) to redesign the front axle casing of their L90 wheel loader to be more in line with their larger wheel loaders. The current L90 front axle casing consists of two parts bolted together in the middle. READ MORE

  3. 2. Life extension of welded steel details in bridges

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Zhelei Jin; [2023]
    Keywords : Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Abstract : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. READ MORE

  4. 3. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jiaqi Yang; [2023]
    Keywords : ;

    Abstract : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. READ MORE

  5. 4. Pros and Cons of Using Large Concrete Blocks in an Office Building Structure : Comfort, Stability, Sustainability

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Shwan Baban; Asliyalfani Abolfazl; [2023]
