1. 6. System modelling of a tightening tool

   University essay from KTH/Teknisk mekanik

   Author : Caroline Eriksson; [2020]
   Keywords : ;

   Abstract : With the help of modern computational power it has become much more common to employ simulation driven development. When performing simulations before creating prototypes and actual test, companies can reduce both the time spent on the development and the cost. READ MORE

3. 7. Model parameter estimation for a handheld nutrunner

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Jonathan Fridstrand; Johanna Sturk; [2020]
   Keywords : ;

   Abstract : The purpose of this project is to investigate the angled nutrunner, which is a hand held torque tool often used in the industry to tighten bolted joints. The goal is to estimate parameter values for an existing model that can describe the reaction force and the angular displacement of the tool as a function of the torque transferred to the joint.

4. 8. Design of a Tribometer to Study Friction inThreaded Fastener Interfaces

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Zhan-Jun Lin; [2020]
   Keywords : tribometer; friction coefficient; tightening; pin-on-disc; tribometer; friktionskoefficient; åtdragning av skruvförband; pin-on-disc;

   Abstract : Bolts and nuts are one of most common joining methods since they are simple and low-cost to connect parts. Appropriate clamp force from bolted joint remains resultant joints secured, but higher/lower preload on bolted joint increases risk of the failure of mechanism. READ MORE

5. 9. Tool orientation estimation to control the angle tightening process of threaded joints

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

   Author : Max Thiel; [2019]
   Keywords : angle controlled tightening; tool orientation; extended kalman filter; particle filter; quaternions;

   Abstract : The most common method for securing components to each other during manufacturing of products is by joining these using screws, nuts and bolts. The benefit of using this method is that it is cheap and makes it easy to join and separate components quickly. READ MORE

6. 10. 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
