   Nyckelord :Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

   Sammanfattning : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. LÄS MER

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

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

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

   Sammanfattning : 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. LÄS MER

5. 4. Characterization of machine tool components for drilling operations with intergrated damping system

   Master-uppsats, KTH/Industriell produktion

   Författare :Ho Duong Dong; [2011]
   Nyckelord :;

   Sammanfattning : In recent years the control of tool vibration has emerged as the critical area of scientific development. This is because tool vibration creates sound-noise and unwanted quality surface. Mathematically, the observed tool vibration is a ratio of the force acting on the tool to its dynamic stiffness.

7. 5. Tillämpning av klämkraftsmätning på kritiska förband inom produktion

   Master-uppsats, Lunds universitet/Maskinelement

   Författare :Rickard Holm; Thomas Johansson; [2009]
   Nyckelord :Elongation controlled tightening; Clamp force; Preload; Ultrasound; Screw joints; Scania ; Technology and Engineering;

   Sammanfattning : Title: Elongation controlled tightening Authors: Rickard Holm and Thomas Johansson Supervisors: Magnus Danielson, Head of DEMD, Scania CV AB Tor Ronnholm – Quality Technician, DEMD, Scania CV AB Unto Ojaniemi – Quality Engineer, DEMD, Scania CV AB Problem Discussion: Within Scania’s engine assembling the engines are assembled, tested and painted. Based on the customers increased demands on higher power and torque, longer service life, experienced quality and decreasing of weight Scania increases their demands on their engines. LÄS MER
