Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mass damper systems face challenges in maintaining damping characteristics under centrifugal force, which can lead to deformation of flexible enclosures and adverse effects on damping behavior.
Innovation Solution
A mass damper system design featuring a stop with a deformation-resistant stop carrier made of metal and a deformation-prone stop damper connected via a radial securing element, along with a pressure medium supply to minimize friction, ensures shape retention and optimal damping performance even under centrifugal force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible enclosure is used as a stop damper, then excellent damping characteristics are achieved, but the enclosure deforms under centrifugal force at higher speeds
Solution Approach 1:
The stop is divided into two separate constructional units: a stop carrier that provides structural support and a stop damper that provides damping functionality. This segmentation allows each component to be optimized for its specific function without compromise.
Solution Approach 2:
The stop combines a metal stop carrier (deformation-resistant material) with a plastic stop damper (deformation-prone material) to create a composite structure that exhibits both structural integrity and damping characteristics.
2Reliability
If a deformation-prone stop damper is used, then excellent damping characteristics are achieved, but the stop damper cannot retain its shape under centrifugal force
Solution Approach 1:
The stop is divided into two separate constructional units: a stop carrier that provides structural support and a stop damper that provides damping functionality. This segmentation allows each component to be optimized for its specific function without compromise.
Solution Approach 2:
The radial securing element acts as an intermediary that connects the stop damper to the stop carrier, providing mechanical support and preventing the stop damper from deforming under centrifugal force while allowing it to maintain its damping characteristics.
3Shape
If the stop damper is secured to the stop carrier, then shape retention is improved, but the damping characteristics may be restricted
Solution Approach 1:
The radial securing element provides localized support at specific connection points between the stop damper and stop carrier, allowing the stop damper to maintain its shape where needed while preserving its ability to deform and provide damping in its functional contact areas.
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
The design maintains consistent damping characteristics and shape retention of the stop damper, effectively addressing the issue of deformation under centrifugal force and enhancing the system's performance.
Implementation Method 1
the at least one stop damper is made from a material such as a plastic that is at least substantially prone to deformation
Implementation Method 2
the desired damping characteristics could accordingly be restricted
Implementation Method 3
the latter benefits from the deformation resistance of the stop carrier in that it retains its shape at least substantially also under the influence of centrifugal force

AI summary
A mass damper system is provided with a damper mass carrier at which damper masses are relatively movably received and a stop is fastened. The damper masses are arranged radially outwardly of the stop and provided at their radial sides facing the stop with contact areas that cooperate with profile areas provided at the stop and which are provided at radial sides facing the damper masses. The stop has at least one stop carrier and at least one stop damper connected to the stop carrier via a radial securing element.
