Compressor Roller Stiffening Arrangement for Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil compactors with divided rollers experience unfavorable vibration behavior due to oscillating movements, leading to noise and potential damage to the rollers and suspension components.
Innovation Solution
A compacting roller design featuring a stiffening arrangement with a stiffening ring and assembly that connects to the roller disc, providing sufficient rigidity to prevent deformations and vibrations, including a thick roller disc and strategically positioned stiffening plates to enhance structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a divided roller design with oscillating movement is used, then compaction effectiveness is improved, but vibration and noise increase
Solution Approach 1:
The roller is divided into multiple independent compressor rollers that can rotate in succession, allowing each roller to be independently controlled and reducing overall vibration through segmentation of the compaction function
Solution Approach 2:
The roller system incorporates oscillating movement capability where compressor rollers can perform periodic back-and-forth movements in the circumferential direction, dynamically adjusting the compaction action to improve effectiveness while the stiffening arrangement controls the resulting vibrations
2Strength
If roller disc thickness is increased to prevent deformation, then structural rigidity is improved, but interior space for system components is reduced
Solution Approach 1:
Instead of uniformly increasing the entire roller disc thickness, stiffening arrangements are applied locally at specific positions where deformation occurs, providing necessary rigidity while preserving interior space in other regions for system components
Solution Approach 2:
The stiffening arrangement extends in the axial direction perpendicular to the roller disc plane, providing structural support through a different dimensional approach rather than simply increasing disc thickness, thus maintaining interior space
3Stability of the object's composition
If a stiffening arrangement is added to prevent vibration, then structural stability is improved, but device complexity increases
Solution Approach 1:
The stiffening arrangement utilizes a stiffening ring and plate structure that provides high structural stability with relatively simple geometry, avoiding complex mechanisms while effectively preventing roller deformation and vibration
Solution Approach 2:
The stiffening ring is integrated with the roller shell structure, and the stiffening plate connects the roller disc to the stiffening ring, merging multiple structural elements into a unified arrangement that provides comprehensive stiffening without excessive complexity
