  1. 1. Development and study of noise generation from propellers

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

    Author : Anton Anton Dunström; Fredrik Skjernov; [2022]
    Keywords : Silent propellers; Propeller development; Noise generation; Skew angle; Blade Area Ratio; Openprop; NATO STANAG no. 1136; Swedish defense and Research Agency FOI ; James Fisher Defense.; Tysta propellrar; Propellerutveckling; Ljudskapande; Skevningsvinkel; Bladtäckningsarea; Openprop; NATO STANAG no. 1136; FOI; James Fisher Defense.;

    Abstract : Noise generation from underwater activities propagates into the marine environment.For marine vessels the propulsion system generates the most noise during itsoperations. Naval vessels that want to operate without being detected want to controlthe sound generating properties of the vessel. READ MORE

  3. 2. Analysis of a Prefabricated Concrete Skew Angle Slab Bridge

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Pär Bengtsson; Johan Wallin; [2019]
    Keywords : Finite Element Model; Skew Angle Slabs; Slab Bridge; Prefabrication;

    Abstract : Prefabricated concrete elements are widely used in the construction industry today. With advantages such as time savings, increased safety at the construction site and minimized material usage, prefab becomes a major challenger to the traditional on-site casting construction method.

  4. 3. Distribution of stresses and displacements in skewed concrete slabs

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Eman Ismail; [2017]
    Keywords : Skew Slab; Finite Element Analysis; FEM; slab behavior;

    Abstract : A 3D nonlinear finite element analysis was developed for simulating the behavior of skewed concrete slabs and to identify the response of the slab with different angles and element sizes. The purpose of this research is helping the engineering and construction industry to utilize the FEM study and results more in different structural applications. READ MORE

  5. 4. Control of Torsionalpendulum on Containercranes

    University essay from Institutionen för systemteknik

    Author : Pär Bäck; [2004]
    Keywords : Reglerteknik; STS-crane; skew-angle; torsional pendulum; MPC-control; LQG-control; statefeedback control; kalman estimation; Reglerteknik;

    Abstract : A container crane of STS-type, Ship To Shore, consists of a spreader hanging underneath a railrunning trolly. As the container is under the influence of wind, it is likely that it starts to turn in a torsional pendulum. This report handles how the torsional pendulum of a container crane can be damped.
