  2. 1. Towards active engine mounting systems for commercial vehicles: modeling and analysis

    Author : Hoda Yarmohamadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear dynamic stiffness and damping; Actuators; Computational model; Conventional engine mount; Vibration isolation; Adaptronic mounting system; Model errors tolerance; Commercial vehicles;

    Abstract : The vehicle engine mounting system, which consists of several mounts connecting the engine to the vehicle structure, not only supports the weight of the engine but also isolates the noise, vibration and the transmitted forces to the vehicle structure. At present conventional elastomeric mounts are widely used in engine mounting systems for commercial vehicles. READ MORE

  4. 2. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

    Author : Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

    Abstract : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. READ MORE
