1. A study of active-passive damping treatments
Sammanfattning : Active Constrained Layer (ACL) treatment is a vibration-damping treatment which consists of a viscoelastic layer constrained by an actuator. It dissipates energy simultaneously by the shearing of the viscoelastic layer and by the action of the actuator. LÄS MER
2. On Contact Mechanisms and Mechanical Transmission Performance
Sammanfattning : This thesis consists of four papers, which treat the modelling of a spur gear set and a disc brake, and the interaction between the machine elements. Features of the performance are studied in relation to the initial stated assumptions. LÄS MER
3. Modeling of Elasticity and Damping for Filled Elastomers
Sammanfattning : Elasticity and damping are significant properties of rubber, taken advantage of in engineering applications. It is therefore important that the constitutive model accurately captures these aspects of the mechanical behavior. LÄS MER
4. Dynamic contact stiffness and air-flow related source mechanisms in the tyre/road contact
Sammanfattning : Two aspect of phenomena occurring in, and in the vicinity of the contact patch formed by a tyre rolling on a road are here investigated: 1. A detailed numerical time domain contact model is used to evaluate approximations of the tread response that are commonly embraced in tyre/road interaction models. 2. LÄS MER
5. Fractional Calculus and Linear Viscoelasticity in Structural Dynamics
Sammanfattning : The use of linear viscoelasticity together with fractional calculus in time-domain structural modeling is studied. Both constitutive and structural aspects are investigated. LÄS MER
