Absorber Mass Damping Arrangement with Carrier-Integrated Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing damping arrangements for absorber systems face limitations in size and weight, restricting the inertial effect of absorber masses due to the need for space-consuming damping devices, which compromise impact damping performance.
Innovation Solution
A damping arrangement featuring a damper element with a dimensionally stable carrier and a deformable support, integrated into the absorber mass carrier, utilizing radial projections and axial locks to provide effective stopping without increasing the absorber mass's dimensions or weight, and employing a form-fitting connection between components for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a damping device is added to the absorber mass, then impact damping performance is improved, but the absorber mass dimensions and weight are reduced due to space limitations
Solution Approach 1:
The damping element is extracted from the absorber mass itself and placed in a recess in the absorber mass carrier. This separation allows the absorber mass to maintain its full weight and dimensions while the damping function is provided by the dedicated damping element with deformable support material.
Solution Approach 2:
A dimensionally stable carrier acts as an intermediary between the absorber mass carrier and the deformable damping support. The carrier provides structural stability while the deformable support material provides the damping function, combining the benefits of both rigid and compliant materials.
2Reliability
If a damping device is added to the absorber mass, then impact damping performance is improved, but the available space for the absorber mass is reduced
Solution Approach 1:
The damping element is extracted from the absorber mass itself and placed in a recess in the absorber mass carrier. This separation allows the absorber mass to maintain its full dimensions while the damping function is provided by the dedicated damping element.
Solution Approach 2:
The damping element is nested within a recess in the absorber mass carrier, utilizing otherwise unused space. The dimensionally stable carrier is accommodated in the recess, and the deformable support material is accommodated on the carrier, creating a compact nested structure.
3Reliability
If a metal damping device is used, then stopping function is provided, but the mass of the damping arrangement is considerably increased
Solution Approach 1:
The damping element combines a dimensionally stable material (such as plastic or metal) for the carrier with a deformable material (such as elastomer or plastic) for the support. This composite structure provides both the structural integrity needed for the stopping function and the compliance needed for soft contact, while being lighter than solid metal constructions.
4Object-affected harmful factors
If the damper element is made soft for low-noise operation, then noise is reduced, but the structural stability and deformation resistance decreases
Solution Approach 1:
The damping element is segmented into two distinct components: a dimensionally stable carrier that provides structural stability and resistance to deformation, and a deformable support material that provides soft contact for low-noise operation. Each component is optimized for its specific function.
Solution Approach 2:
The damping element combines a dimensionally stable material (such as plastic or metal) for the carrier with a deformable material (such as elastomer or plastic) for the support. This composite structure provides both the structural integrity needed for stability and the compliance needed for low-noise operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances impact damping performance while maintaining the absorber mass's weight and size, ensuring effective stopping in both radial and circumferential directions with reduced wear and noise, even under centrifugal forces.
Implementation Method 1
a damper element support (7) accommodated on the damper element carrier (6) as a second component made of an at least essentially deformable material
Implementation Method 2
an axial lock (72, 74) can be assigned to the damper element carrier (6) and thus to the first component
Implementation Method 3
The first component is particularly advantageously designed with a geometric profiling on its side facing the second component, with a counter-profiling being formed when the second component is sprayed on, which is in a form-fitting connection with the profiling of the first component

AI summary
A damping arrangement for at least one absorption mass, accommodated on an absorption mass carrier, of an absorption system is provided with a damping device assigned to the at least one absorption mass, which serves as a stop – both in the radial direction and in the circumferential direction – for the respective absorption mass, wherein the damping device has at least one damping element which is assigned to the absorption mass carrier, at least along part of the circumferential extent of the latter. The damping element has a first component in the form of a damping element carrier which is accommodated on the absorption mass carrier, in a recess provided therefor, and serves to accommodate a second component in the form of a damping element cushion which projects, with a radial projection acting as a stop for the respective absorption mass, into the installation space provided in the absorption mass carrier for the movement of the respective absorption mass.
