Device for fixing reactor modules to a test bench
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for testing reactor modules in test benches fail to achieve a balance between suppleness, resistance, and low bulk, making them inadequate for simulating the fixing of new-generation turboreactors with increased weight and bulk.
Innovation Solution
A suspension device with a flexible median area in its suspension arm, where the cross-section dimension is less than at the attachment ends, allowing for adaptable mechanical constraints and reduced rigidity in less stressed areas, ensuring optimal suppleness and resistance while minimizing bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a suspension device with sufficient resistance is used to mechanically maintain reactor modules, then the device can support heavier reactors, but the bulk of the suspension device increases making it difficult to fit in the test bench
Solution Approach 1:
The suspension arm features a variable cross-section design where the median area has a reduced cross-section dimension compared to the attachment ends. This local quality variation allows the arm to have sufficient resistance at the attachment points while maintaining suppleness and reducing bulk in the median area, resolving the contradiction between strength and volume.
2Strength
If a suspension device with sufficient resistance is used to mechanically maintain reactor modules, then the device can support heavier reactors, but the complexity of the device structure increases
Solution Approach 1:
Instead of using multiple separate components or complex mechanisms to achieve sufficient resistance, the invention modifies the local quality of a single suspension arm by varying its cross-section. This approach achieves the required resistance while maintaining structural simplicity, resolving the contradiction between strength and complexity.
3Volume of stationary object
If the cross-section dimension of the suspension arm is reduced to decrease bulk, then the device becomes more compact, but the mechanical resistance of the arm decreases
Solution Approach 1:
The suspension arm has different cross-section dimensions at different locations: the attachment ends maintain larger dimensions for sufficient resistance, while the median area has reduced dimensions for decreased bulk. This spatial variation in local quality resolves the contradiction between bulk and resistance.
Solution Approach 2:
The suspension arm is effectively segmented into different functional zones along its length, with the median area distinguished from the attachment ends by having a different cross-section dimension. This segmentation allows each zone to optimize for its specific function, resolving the contradiction between bulk and resistance.
