  1. 1. Thermo-mechanical vibration technique for degating of high-pressure die casting component – A numerical study

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Ramkumar Kandasamy; [2023]
    Keywords : High-pressure die casting; Thermo-mechanical vibration; Finite Element Method; ANSYS WB.;

    Abstract : The purpose of the thesis work given is to gain a better understanding of the degating process in high-pressure die casting components, as well as the effectiveness of the thermo-mechanical vibration technique for detaching cast components from the gating system. In addition, to evaluate and establish the most appropriate degating procedure in order to reduce labor, material costs, and processing time. READ MORE

  3. 2. Measurement of mechanical vibrations : Measurement of ambient energy in the form of mechanical vibrations in transportation, storage and installment for the use of self-powered wireless sensor networks

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

    Author : Oskar Nordström; [2023]
    Keywords : ;

    Abstract : This project aims to explore the feasibility of using energy harvesting to create a self-powered sensor node that doesn't require batteries. The project was initiated by Ericsson, who identified a need to monitor their radio products during delivery to ensure they are not damaged by vibrations that exceed design specifications. READ MORE
