摘要： The invention relates to a vibration damper for application to a vehicle bottom plate (1), comprising an under floor panel (3) as a constraining layer and a damping layer (2) as a constrained layer, wherein the damping layer (2) has a lower modulus of elasticity than the under floor panel (3), and wherein the damping layer (2) is located between the vehicle bottom plate (1) and the under floor panel (3) when the vibration damper is fixed to the vehicle bottom plate (1). The vibration damper is characterized in that the under floor panel (3) is pre-shaped and stays in this shape when fixed to the vehicle bottom plate (1) and is made of a first polymeric material, and that the damping layer (2) is made of a non-foamy second polymeric or bitumen material and is placed on the under floor panel (3) prior to fixation of the vibration damper to the vehicle bottom plate (1). In addition, the invention relates to a respective damping arrangement and a method of producing a vibration damper.
