Problem
Existing Junker test machines are large and impractical for demonstration or rapid testing of multiple fasteners, and they only accommodate one fastener at a time, making it difficult to compare different fasteners and threadlockers effectively.
Innovation Solution
A vibration testing apparatus with a test station and preparation station, featuring a motorized drive assembly for reciprocating transverse motion, a controller, and a sensor system to evaluate fastener performance under vibration, allowing for simultaneous testing and comparison of multiple fasteners and threadlockers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known Junker test machines are used, then fastener vibration testing can be performed, but the machines are large and not easily transported
Solution Approach 1:
The testing system is divided into separate functional modules: a preparation station for assembling test pieces and a test station for vibration testing. This modular segmentation allows the system to be compact and portable while maintaining full testing functionality.
Solution Approach 2:
The test station is designed to accommodate multiple different fastener types and configurations through universal fixtures and adjustable components, allowing one compact device to perform various vibration testing functions that previously required multiple large specialized machines.
2Reliability
If known Junker test machines are used, then single fastener testing can be performed, but testing multiple fasteners in a short period is problematic
Solution Approach 1:
The preparation station allows multiple test pieces to be assembled and pre-positioned before vibration testing begins. This preliminary preparation enables the test station to immediately test multiple fasteners in sequence without setup delays, significantly increasing productivity while maintaining single-fastener testing accuracy.
Solution Approach 2:
The system enables continuous testing operations where the preparation station continuously prepares test pieces while the test station continuously performs vibration testing. This overlapping of preparation and testing operations eliminates idle time and maximizes the throughput of multiple fastener evaluations.
3Reliability
If known Junker test machines are used, then fastener testing can be performed, but it is difficult to compare different fasteners and threadlockers
Solution Approach 1:
The test station incorporates universal fixtures, standardized test piece designs, and consistent vibration parameters that can accommodate various fastener types, sizes, and threadlocker configurations. This universality ensures all fasteners are tested under identical conditions, enabling direct comparison of different fastener and threadlocker performances.
Solution Approach 2:
The system allows easy adjustment of vibration parameters, test piece configurations, and measurement settings to optimize testing for different fastener types. These parameter changes maintain consistent testing protocols across all samples while adapting to specific fastener characteristics, facilitating reliable comparative analysis.
