  1. 11. Ergonomic Evaluation of Power Tool Use at Different Task and Tool Related Conditions Using a Mechanical Test Rig, Electromyography and Subjective Evaluations

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ava Mazaheri; [2018]
    Keywords : Power Tools; Tightening Tools; Ergonomics; Subjective Ratings; Torque Tools;

    Abstract : Workers within production and assembly lines are often exposed to ergonomically unfavorable tasksand conditions. Reaction forces and reaction torques generated by industrial power tools may causenot only discomfort but also health issues and injury. READ MORE

  2. 12. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Turgay Dagdelen; Shaho Ruhani; [2018]
    Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

  4. 14. Bearing Strenght of Thin ply Carbon fiber Laminates

    University essay from KTH/Lättkonstruktioner

    Author : Johan Larsson; [2018]
    Keywords : ;

    Abstract : The lighter an object is the easier it is to send into space. This principle is what drives the never ending hunt for lighter structures in the space industry. One way to reduce weight is to replace existing materials with lighter ones. Polymer matrix composites are such materials, as their density is lower than both steel and aluminium. READ MORE

  5. 15. Horizontal natural frequency in a 10 story building : A comparison between CLT and concrete using estimate calculations

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Jennifer Eriksson; [2018]
    Keywords : Horizontal natural frequency; tall timber building; timber structure; CLT; wind induced motion; tall CLT building; Horisontell egenfrekvens; hög träbyggnad; höga trähus; KL-trä; vindinducerade rörelser; högt KL-hus;

    Abstract : Tall slender buildings are easily set in motion by wind and earthquakes but by estimating the buildings horizontal natural frequencies in the design phase, these motions can be kept within acceptable boundaries. There are many parameters that decides the natural frequency of a building and it can therefore be difficult to calculate it. READ MORE
