Wire Rope Suspension Assembly for Wide-Temperature Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration damping solutions for sensitive devices during transportation are inadequate, particularly due to temperature-dependent damping materials and inefficient handling of vibrations across varying temperatures and directions.
Innovation Solution
A suspension assembly using wire rope isolators and a damping support member, configured with inclined support plates and base arrangements, provides effective vibration isolation and damping through multiple mechanisms, including isolation, friction, and absorption, maintaining damping properties over a wide temperature range and handling vibrations in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature-dependent damping materials (such as rubber and elastomers) are used, then damping properties are sufficient within a certain temperature interval, but damping properties become insufficient outside that temperature interval
Solution Approach 1:
The patent combines wire rope isolators with rubber or elastomer dampers to create a composite vibration isolation system. The wire rope isolators provide temperature-independent isolation, while the rubber/elastomer components provide damping within their effective temperature range. This composite approach ensures reliable vibration isolation across a wide temperature interval from -33°C to +63°C, resolving the contradiction between maintaining damping properties and adapting to varying temperatures.
2Reliability
If wire rope isolators are arranged between inclined support plate portions and inclined base arrangement portions, then vibration isolation and damping are improved, but the device complexity increases
Solution Approach 1:
The support plate is divided into a centre portion and at least two side portions extending with an inclination angle outwardly from the centre portion. The base arrangement includes at least two inclined portions that extend essentially in parallel with the side portions of the support plate. This segmentation allows wire rope isolators to be arranged between the inclined portions, creating effective vibration isolation through geometric configuration while maintaining a relatively simple overall structure.
3Reliability
If damping support member and wire rope isolators are combined, then damping characteristics are improved, but the volume of the suspension assembly increases
Solution Approach 1:
The wire rope isolators are arranged between the inclined side portions of the support plate and the inclined portions of the base arrangement, effectively nesting the isolation mechanism within the geometric configuration of the support structure. The damping support member is integrated with the centre portion of the support plate, allowing the damping function to be incorporated without significantly increasing the overall volume of the suspension assembly.
