Bent Piping Member Structure for Pulsation Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid transport devices face vibration issues due to pulsating fluid discharge, which complicates the structure and increases costs when using flexible connecting portions to mitigate resonance vibrations.
Innovation Solution
A piping member with a tubular portion and flange portions at both ends, where the flange portions are directly connected to form a bent portion, enhancing rigidity and reducing vibration, and optionally reinforced with a connecting member, made of casting for simplified structure and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible connecting portion is provided to suppress vibration, then vibration resistance is improved, but device complexity and cost increase
Solution Approach 1:
The piping member incorporates a bent portion that provides flexibility to absorb vibration while maintaining structural integrity. This dynamic design allows the pipe to flex and dampen pulsating forces from the air compressor without requiring separate flexible connecting portions, thus improving vibration resistance while keeping the structure simple.
Solution Approach 2:
The invention changes the geometric parameters of the piping member by introducing a bent portion with specific curvature and angle. This parameter modification allows the rigid-looking structure to actually possess flexible characteristics that suppress vibration, resolving the contradiction between structural simplicity and vibration resistance.
2Reliability
If a flexible connecting portion is provided to suppress vibration, then vibration resistance is improved, but manufacturing cost increases
Solution Approach 1:
The invention merges the functions of vibration suppression and fluid transport into a single integrated piping member. The bent portion serves both as the structural element for fluid flow and as the vibration-dampening feature, eliminating the need for separate flexible connecting portions and reducing manufacturing cost.
Solution Approach 2:
By modifying the geometric parameters of the piping member (introducing bends at specific angles and positions), the invention achieves vibration resistance through design rather than through expensive flexible components, thereby reducing manufacturing cost while maintaining reliability.
3Reliability
If a flexible connecting portion is provided to suppress vibration, then vibration resistance is improved, but space requirement increases
Solution Approach 1:
The bent portion is designed to provide the necessary flexibility and vibration damping within the existing spatial constraints of the system. By optimizing the bend radius and angle, the invention achieves vibration suppression without requiring excessive space for the flexible connecting portion.
Solution Approach 2:
The invention optimizes the geometric parameters of the bent portion (curvature radius, bend angle, length) to achieve vibration resistance within the available space. This parameter optimization allows the piping member to suppress vibration without requiring additional space that would be needed for separate flexible connecting portions.

AI summary
A vibration suppressing piping member suppresses vibration caused by a pulsating discharged gaseous fluid. The piping member includes a tubular portion and flange portions at both ends of the tubular portion. A bent portion is formed between the two flange portions. The two flange portions are directly connected to each other.
