Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration mounts for rotating electric machines are complex to manufacture due to their high number of elements, which complicates the minimization of vibration transfer from the rotor to the machine's structural components.
Innovation Solution
The anti-vibration mount comprises a first and second support part separated by a gap, with at least one damping module consisting of enveloping surfaces and vibration damping elements connecting these surfaces, allowing for efficient vibration damping while reducing the number of mount elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional support structures with multiple elements (mounting plates, reaction plates, intermediate support members, elastomeric layers) are used to minimize vibration transfer, then vibration damping performance is improved, but device complexity increases making manufacturing complex
Solution Approach 1:
The patent combines multiple traditional support structure elements (mounting plates, reaction plates, intermediate support members, and elastomeric layers) into a single integrated anti-vibration mount body. The mount body directly integrates the damping function through its material composition rather than using separate elastomeric layers, thereby reducing the number of parts while maintaining vibration damping performance.
Solution Approach 2:
The anti-vibration mount body serves multiple functions simultaneously: it acts as both the structural support element and the vibration damping element. The mount body is designed to provide mechanical support while its viscoelastic material composition provides inherent damping properties, eliminating the need for separate damping components.
2Reliability
If a gap is maintained between support parts to prevent excessive compression of damping elements, then reliability of damping function is improved, but device complexity increases due to additional positioning requirements
Solution Approach 1:
The patent employs a resilient connection between the first and second support parts that allows dynamic adjustment of the gap. The resilient means enables the support parts to move relative to each other while maintaining an average gap distance, adapting to varying compression forces during machine operation without requiring complex fixed positioning structures.
3Ease of manufacture
If the number of mount elements is reduced to simplify manufacturing, then ease of manufacture is improved, but vibration damping performance may deteriorate
Solution Approach 1:
The anti-vibration mount body is constructed from a composite material system consisting of a rigid structural framework and a viscoelastic damping material. This composite structure provides both the mechanical strength needed for support and the vibration damping properties of the viscoelastic material, achieving effective vibration isolation in a single integrated component.
Solution Approach 2:
The patent optimizes the viscoelastic material parameters (such as loss factor, stiffness, and damping coefficient) to ensure that the single-integration mount body provides sufficient vibration damping performance. By carefully selecting and tuning these material parameters, the design achieves effective vibration isolation without requiring multiple separate elements.
