2. 6. Advances In Heavy Vehicle Dynamics with Focus on Engine Mounts and Individual Front Suspension

   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; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration isolation; semi-active damper; handling; heavy vehicle; individual front suspension; nonlinear dynamic stiffness and damping; kinematics; adaptronic mounting system; engine mount; comfort;

   Abstract : The main objective of the research presented in this thesis is to enhance driver comfort and handling of a heavy truck that in turn leads to better vehicle safety and stability. The focus has been put on studying two suspension systems of the truck, engine and front axle suspensions, due to their significant impact on the dynamic performance of the vehicle. READ MORE

4. 7. Measurement and Application of Multidirectional Mobilities

   Author : Michael A. Sanderson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source signal filtering; mass loading; rotational mobility; rotational inertia loading; multidirectional mechanical mobility; moment mobility; structural intensity; measurement techniques; vibration isolation;

   Abstract : The direct measurement of moment mobility, employing a twin exciter technique, is theoretically and experimentally examined. This is continued by a theoretical and experimental analysis of an improved technique using source signal filtering, for two degrees of freedom, for the measurement of multidirectional mobilities.

5. 8. On the Modelling of Train Induced Ground Vibrations with Analytical Methods

   Author : Anders Karlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; train; wave propagation; dynamic flexibility; trench; railway track; vibration isolation; wave barrier; soil-structure interaction;

   Abstract : A novel analytical approach to model train induced ground vibrations is proposed. Integral transform solutions are combined with series solutions to obtain fast numericalalgorithms, where a particular designed boundary condition for finite regions is seen to enable the solution procedure.

6. 9. Noise and Vibration Control of Combustion Engine Vehicles

   Author : Mathias Winberg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Noise and vibrations have over the last two decades been regarded as significant environmental health problems. Regulations regarding acoustic as well as vibration levels have therefore become more stringent. READ MORE

7. 10. Exploring the vibration control potential of magneto-sensitive rubber

   Author : Peter Blom; Leif Kari; James Busfield; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; magneto-sensitive rubber; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Abstract : Two new aspects of the dynamic behaviour in the audible frequency range of magneto-sensitive (MS) rubber are highlighted: the existence of an amplitude dependence of the shear modulus—referred to as the Fletcher–Gent effect—for even small displacements, and the appearance of large MS effects. These results have been obtained experimentally and are subsequently used to model two examples of magneto-sensitive rubber isolators to show how by means of MS rubber they can be improved. READ MORE
