  1. 16. FE based method for simulation of rock-loading on a truck

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Tamim Kohestani; Ali Zeaiter; [2019]
    Keywords : FEM; Rock loading; Nastran; LS-DYNA; ANSA; META; Contact; Linear; non-linear; Explicit; Implicit.;

    Abstract : Volvos trucks are used to carry boulders of varying sizes from different mining sites or construction sites. These boulders are loaded onto the dumper of the truck by a wheel-loader which drops the boulders from various heights causing an impulse like force which distributes throughout the frame and to the rest of the truck.

  4. 18. Design of a Dynamic Boom Suspension System in a Hybrid Wheel Loader

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Ayoub Ayoub; Carl Martin Berg; [2018]
    Keywords : Wheel loaders; passive damming; active damping; dynamic damping; PID controllers; vibrations; hydraulics.;

    Abstract : Wheel loaders are under the influence of low frequency vibrations that may be harmful for the health of the operator, and for the productivity of the machine. The strong vibrations can significantly impact the operation of the machine since they are not equipped with wheel suspension systems and due to their work environment in rough terrains with uneven surfaces.
