Anti-Vibration Mount Structure to Prevent Damping Material Over-Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration mounts for machinery are limited in effectively isolating acoustic vibrations due to over-compression of vibration dampening materials, which reduces their effectiveness in suppressing machine-born vibrations.
Innovation Solution
An anti-vibration apparatus featuring a rigid elongate core with a vibration dampening material having recessed portions on its surface, combined with end cap washers and support housings to prevent over-compression and maintain optimal rigidity, allowing for enhanced vibration suppression across various orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration dampening material is used to suppress machine vibrations, then vibration isolation effectiveness is improved, but the material undergoes over-compression which reduces its effectiveness
Solution Approach 1:
The vibration dampening material is segmented into multiple sections along the elongate core, with recessed portions created in each section. This segmentation prevents over-compression by providing expansion spaces, allowing the material to maintain its rigidity and vibration isolation effectiveness throughout operation.
Solution Approach 2:
The recessed portions create a porous-like structure within the vibration dampening material, providing internal expansion spaces. This allows the material to compress and expand dynamically during vibration cycles without permanent deformation, maintaining its damping properties and preventing over-compression failure.
2Force
If vibration dampening material is compressed to support machine weight, then load-bearing capacity is improved, but the material loses its ability to dampen vibrations
Solution Approach 1:
The vibration dampening material is designed to dynamically adjust its compression state through the recessed portions. Under static load, the material compresses to support weight, while the recessed portions provide expansion space that allows the material to dynamically recover and maintain its dampening capability during vibration cycles.
3Adaptability or versatility
If the anti-vibration mount is designed for vertical orientation, then it effectively supports machine weight, but it cannot function effectively in horizontal orientations
Solution Approach 1:
The anti-vibration mount design with recessed portions in the vibration dampening material creates a universal solution that functions effectively in both vertical and horizontal orientations. The recessed portions provide expansion spaces that work regardless of orientation, allowing the same component to maintain its vibration suppression performance across multiple mounting configurations.
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 solution significantly improves acoustic vibration isolation by providing additional expansion space for the vibration dampening material, maintaining its rigidity and effectiveness, and enabling the anti-vibration mount to function effectively in both vertical and horizontal orientations.
Implementation Method 1
a vibration dampening material, such as for example an elastomer material coating the outer surface of the core
Implementation Method 2
the vibrations caused by the machine oscillate at a frequency, which passes into the vibration suppression mount and is dampened as it passes through the vibration dampening material surrounding the core
