Modular Elastic Hydraulic Support for Wind Turbine Vibration Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic hydraulic support apparatuses in wind power generation systems face challenges with difficult maintenance and high maintenance costs due to their complex structure and high rigidity, which complicates the reduction of vibration and load-bearing capabilities.
Innovation Solution
The apparatus is designed with an elastic module and a hydraulic module that are configured as independent units, allowing for easier assembly and maintenance, featuring elastically compressible bodies, reinforcing members, and hydraulic chambers that work together to provide high torsional rigidity and low vertical rigidity, with a hydraulic sealing membrane and fixing member to manage fluid flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the elastic hydraulic support apparatus uses a complex integrated structure to achieve high torsional rigidity and load-bearing capability, then the support performance and vibration reduction are improved, but the maintenance difficulty and replacement complexity increase significantly
Solution Approach 1:
The support apparatus is divided into distinct functional modules: elastic elements (first and second elastic bodies), hydraulic elements (hydraulic chamber with sealing membrane), and reinforcing members. These modules are connected through mounting members that allow individual access and replacement, enabling maintenance of specific components without dismantling the entire structure.
Solution Approach 2:
The hydraulic chamber with sealing membrane is designed as a separable component that can be extracted and replaced independently from the elastic bodies and mounting members. This extraction capability allows the hydraulic element to be maintained or replaced without affecting the structural integrity of the remaining components.
2Strength
If the elastic hydraulic support apparatus uses a complex integrated structure to achieve high torsional rigidity, then the load-bearing capability is improved, but the maintenance cost increases
Solution Approach 1:
The apparatus is segmented into standardized modules with mounting members that facilitate easy assembly and disassembly. This modular design reduces manufacturing complexity of individual components and enables cost-effective maintenance through selective replacement rather than complete system overhaul.
Solution Approach 2:
The mounting members are designed to universally connect different types of elements (elastic bodies, hydraulic chambers, reinforcing members), allowing a single mounting component to serve multiple functions and reduce the variety of spare parts needed, thereby lowering maintenance costs.
3Stability of the object's composition
If the elastic hydraulic support apparatus uses high rigidity design to reduce vibration, then the vibration reduction effect is improved, but the maintenance complexity increases
Solution Approach 1:
The rigid structure is achieved through carefully designed connections between modular components rather than a monolithic structure. The mounting members provide stable connections while allowing individual components to be accessed, simplified, and maintained without compromising the overall structural rigidity required for vibration reduction.
