Server Limiting Jig for Vibration Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration testing systems for servers often experience test failures due to gaps formed between stoppers and the server, leading to incomplete and excessive output waveforms.
Innovation Solution
A vibration testing device equipped with a limiting jig that includes a base and multiple limiting assemblies, which use a combination of guiding portions, limiting portions, and guide rods to securely position the server in three directions, preventing displacement and ensuring stable contact during tests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If stoppers are used to fix the server in the horizontal direction on a platform, then the server positioning is simplified, but gaps may be formed between the stopper and the server during the test, resulting in incomplete output waveforms and test failure
Solution Approach 1:
The positioning structure is divided into multiple limiting assemblies (first limiting assembly, second limiting assembly, third limiting assembly) that work together to constrain the server in three different directions. Each assembly has specific limiting portions that contact different surfaces of the server, ensuring comprehensive positioning without gaps.
Solution Approach 2:
The positioning system transitions from simple horizontal stopping to three-dimensional constraint by adding limiting assemblies that operate in multiple directions (first direction, second direction, and third direction perpendicular to the first two). This multi-directional approach eliminates gaps by constraining the server from all spatial dimensions.
2Device complexity
If simple stoppers are used for server fixation, then the device structure is simpler, but the output waveform becomes incomplete and exceeds specified range, causing test failure
Solution Approach 1:
The limiting jig is segmented into multiple independent limiting assemblies, each responsible for constraining the server in a specific direction. This segmentation allows precise control over the server's position and movement, ensuring that the output waveform remains within the specified range and maintains manufacturing precision.
Solution Approach 2:
The limiting portions act as intermediary elements between the limiting assemblies and the server. These limiting portions make direct contact with the server surfaces and transmit the constraining forces, ensuring precise positioning and controlled movement that maintains output waveform precision.

AI summary
A limiting member includes a guiding portion, a first limiting portion slidably connected to the guiding portion for contacting a server. A first guide rod is threadedly connected to the guiding portion, with one end abutting against the first limiting portion to push it into contact with the server. There is also a second limiting portion arranged on the first limiting portion and slidably connected to the guiding portion for contacting the server. A second guide rod is threadedly connected to the guiding portion, with one end abutting against the second limiting portion to push it into contact with the server.
