  1. 21. Shock Load Absorption of Electro-mechanical Actuators

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

    Author : Kenan Güler; Milan Andelkovic; [2021]
    Keywords : Shock loads; electro-mechanical actuators; load absorption; Stötbelastningar; elektro-mekaniska ställdon; dämpningsförmåga;

    Abstract : När ett ställdon får som krav att kunna överföra höga krafter i relativt höga hastigheter med en dessutom väldigt hög precision är elektromekaniska ställdon oftast att föredra. En traditionell pinjong-kuggstång-uppställning uppfyller vissa av de kraven, men om kraften ska ökas behövs det fler än ett pinjongpar. READ MORE
