1Object-affected harmful factors
If traditional damping materials are used between electronic components, then vibrations can be reduced, but the damping effectiveness is insufficient and unwanted resonances persist
Solution Approach 1:
The patent employs a composite damping material comprising rubber particles dispersed in a polymer matrix, combined with carbon nanotubes. This composite structure leverages the viscoelastic properties of rubber for energy dissipation while the carbon nanotubes enhance structural integrity and damping effectiveness, resolving the insufficiency of traditional single-material damping solutions
Solution Approach 2:
The patent modifies the damping material by incorporating carbon nanotubes with specific surface area characteristics (400-2500 m2/g) and controlling rubber particle size and distribution. These parameter changes enhance the material's ability to convert vibrational energy into heat, significantly improving damping effectiveness over conventional materials
2Stability of the object's composition
If components are mounted directly to frames or brackets, then structural stability is maintained, but vibrations are transmitted and resonances are created
Solution Approach 1:
The patent introduces a damping material layer as an intermediary between electronic components and structural frames or brackets. This intermediate layer decouples the direct mechanical connection, allowing structural stability to be maintained while vibrations and resonances are absorbed and dissipated within the damping material
Solution Approach 2:
The damping material is applied as a thin film or layer between components and structural elements. This flexible intermediate layer provides vibration isolation while maintaining the structural integrity and positional stability of mounted components
