  1. 16. Active Vibration Control of Multibody Systems : Application to Automotive Design

    Författare :Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

    Sammanfattning : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. LÄS MER

    Sammanfattning : Climate change and densification of cities are two major global challenges. Inthe building and construction industry, there are great expectations that tall timberbuildings will constitute one of the most sustainable solutions. First, verticalurban growth is energy and resource-efficient. LÄS MER

  4. 18. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling

    Författare :Penka Dinkova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration response; mobility measurements; truck tyre; heavy vehicle; tyre-road noise; tyre; driving point mobility; transfer mobility; tire; vibration prediction; model;

    Sammanfattning : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available. LÄS MER
