Dynamic Damper Mounting Structure for Precise Rubber Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dynamic damper mounting structures face challenges in accurately setting the interval between side plates, affecting the thickness of rubber elastic bodies and the effectiveness of vibration reduction, leading to insufficient vibration suppression of vibration bodies.
Innovation Solution
A dynamic damper mounting structure with separate inhibition and plate members, where the inhibition member is positioned opposite to the mass member, and the interval between them is set to be smaller than the insertion allowance, preventing the mass member from falling off and allowing precise control over rubber elastic body thickness for optimal vibration reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the side plates and coupling plate are integrated, then the structure is simplified, but the opposite interval between side plates cannot be set to the desired interval, affecting vibration reduction effectiveness
Solution Approach 1:
The coupling plate is separated from the side plates, creating independent components. The side plates are fixed to the bracket, while the coupling plate is positioned separately with its position determined by the relationship between the opening and mass member, enabling precise control of the opposite interval between side plates
2Ease of manufacture
If the opposite interval between side plates is not precisely controlled, then manufacturing is easier, but the thickness of rubber elastic bodies cannot be accurately set, affecting vibration reduction performance
Solution Approach 1:
The mechanical constraint system is replaced by a geometric constraint system. The position of the coupling plate is determined by the opening and mass member geometry rather than mechanical fastening, allowing precise control of side plate interval and rubber elastic body thickness through dimensional design
3Volume of moving object
If the mass member insertion allowance is not sufficient, then the structure is more compact, but the mass member may fall off when it contacts the inhibition member
Solution Approach 1:
The design proactively prevents mass member fall-off by ensuring the insertion allowance is sufficient to maintain engagement with the opening even when the mass member contacts the inhibition member. This preliminary consideration of failure modes ensures reliable mass member retention throughout operation

AI summary
A mounting structure of a dynamic damper capable of effectively reducing the vibration of a vibration body is provided. The mounting structure includes a suspension member 100 inhibiting the upward shift of a mass member 5. The suspension member 100 and plates 3 are configured as separate members, so that as compared with the case where a pair of plates 3 are coupled, the opposite interval between the plates 3 can be determined without being affected by the dimension accuracy of such the coupling portion. Thus, the thicknesses of the rubber elastic bodies 4 can foe formed at high accuracy, so that the mass member 5 can be easily vibrated at the desired frequency. Therefore, the vibration of the suspension member 100 can be effectively reduced.
