  1. 16. NG stand mechanical interface analysis for vehicle integrated RBS 70 NG

    University essay from Karlstads universitet

    Author : Adnan Dugalic; [2018]
    Keywords : Vechicle integrated system; vibration;

    Abstract : RBS 70 was introduced 1978 in Sweden and developed to be counter threats on the battlefield. This weapon is efficient against both conventional and small targets. Main components of the system are stand, sight and missile in container. READ MORE

  3. 17. Analytical and Numerical Study of a Passive Self-Tuning Resonator

    University essay from Lunds universitet/Mekanik

    Author : Majeed al Tmizi; [2018]
    Keywords : Energy harvesting; mechanical vibrations; passive self-tuning; beam resonators; string resonators; sliding proof-mass; MEMS; actuators; Technology and Engineering;

    Abstract : Energy harvesting, from ambient vibrations, can be a very effective method for solving the problem with powering electronics were the need for constant power or regular battery replacements is a trouble or an inconvenience. But, since all energy harvesters, using mechanical vibrations, need to operate in resonance in order to generate maximal electrical output, and ambient vibrations usually do not have a constant vibration frequency, this results in the need for efficient self-tuning systems.

  4. 18. Initial concepts to develop a semi-autonomous operator support technology for operating a novel forestry machine

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

    Author : Xiaowei Dong; [2018]
    Keywords : Robotics; Motion planning; Virtual holonomic constraints; Trajectory optimization;

    Abstract : Forestry machines have the power to lift heavy logs, but they are not so smart at providing information, or help operators perform better work. The main reason to this problem is the low level of technology applied to forestry machines, which has not changed so much since the forestry machines were first introduced in the 1960’s. READ MORE

  5. 19. Fretting tests on connector terminals

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Marcus Magnusson; [2018]
    Keywords : Fretting; Corrosion; Laser vibrometry; Connector; Vibration; Technology and Engineering;

    Abstract : Fretting is a complex set of mechanical and electrical mechanics that occurs at the contact surface between two vibrating objects. It is widely present in electrical connectors close to combustion engines due to the constant exposure to vibrations. Fretting is an extensive problem in the automotive industry but little research is done. READ MORE

  6. 20. Detection of stator interturn fault of synchronous machine by rotor current analysis : A SIMULATION APPROACH

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Ata-E Rabbi; [2016]
    Keywords : Synchronous machine; interturn fault; stator fault; rotor current; harmonic current; generator protection; motor protection; inductance matrix.; synkronmaskin; varvfel; statorström; rotorström; strömöverton;

    Abstract : One of the major electrical faults of synchronous machines is an interturn short circuit in the stator winding, due to winding insulation failure. A synchronous machine is designed to have electrical and mechanical symmetry in the stator and rotor. READ MORE
