Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration plate arrangements for connecting machines to foundations fail to effectively dampen and isolate undesirable mechanical oscillations such as vibrations, shocks, and impacts, which can lead to structural damage and operational disruptions.
Innovation Solution
The proposed oscillating plate arrangement incorporates a first base plate connected to the foundation via first vibration dampers and a second base plate connected to the machine via second vibration dampers, with an intermediate plate providing additional damping and isolation, utilizing elastomeric or viscoelastic materials for effective vibration energy absorption and damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple base plate connection is used, then the device complexity is reduced, but the vibration damping effectiveness deteriorates
Solution Approach 1:
The base plate is divided into multiple segments (first base plate, second base plate, intermediate plate) that are spatially separated and connected through vibration dampers. This segmentation allows each component to independently contribute to vibration damping while maintaining structural integrity, resolving the contradiction between simplicity and effectiveness.
Solution Approach 2:
Vibration dampers are introduced as intermediary elements between the base plate segments and between the base plate and the machine. These intermediaries actively dissipate vibration energy while maintaining the structural connection, thereby improving vibration damping effectiveness without significantly increasing overall device complexity.
2Reliability
If multiple base plates and intermediate plates are used, then the vibration damping effectiveness is improved, but the device complexity increases
Solution Approach 1:
The base plate system is segmented into multiple functional components (first base plate for foundation connection, second base plate for machine connection, intermediate plate for additional damping) that work together in a modular fashion. This segmentation enables improved vibration damping through multiple damping interfaces while maintaining manageable structural complexity.
Solution Approach 2:
The system combines different materials with complementary vibration damping properties - elastomeric materials in the vibration dampers for high damping capacity, and metal plates for structural strength and stiffness. This composite approach achieves superior overall vibration damping effectiveness while keeping each individual component relatively simple.
3Loss of energy
If vibration dampers are placed between base plate and foundation, then the vibration energy absorption is improved, but the spatial requirements increase
Solution Approach 1:
The vibration dampers are positioned in the vertical dimension between the base plate and foundation, utilizing the height direction rather than expanding the horizontal footprint. This dimensional approach allows effective vibration energy absorption while minimizing the spatial requirements in the plan view.
Solution Approach 2:
The vibration dampers utilize elastomeric material layers that provide high damping capacity in a thin, compact form factor. These flexible elastomeric elements absorb vibration energy effectively while occupying minimal space, resolving the contradiction between energy absorption and spatial requirements.
