Optimized support structure for membrane deformation prevention
Introducing a rigid support structure between dunnage boards and membrane packs to evenly distribute weight and minimize stress, preventing deformation in PVC and KEE membranes. Optimized using finite element analysis, this solution enhances product quality and transport efficiency.
Overview
The proposed solution addresses the deformation of PVC and KEE membranes during storage and transport by introducing an optimized rigid support structure. By placing this structure between dunnage boards and membrane packs, weight is distributed more evenly, minimizing stress concentrations that lead to indentations and edge bulging. This approach not only prevents deformation but also enhances product quality and extends storage life without altering the core membrane design.
Technical specifications
- Support Structure Materials: Potential materials include honeycomb panels, composites, and reinforced plastic, chosen for their ability to distribute loads effectively.
- Optimization Method: Finite Element Analysis (FEA) is used to simulate static and dynamic forces during storage and transport, optimizing material properties, geometry, and load distribution.
- Deformation Prevention: The design eliminates horseshoe-shaped indentations, ensuring membranes remain flat upon unrolling.
Technology readiness level
Currently at TRL 3, the solution is in the experimental proof of concept stage. Future work includes detailed FEA to simulate transport conditions and experimental validation with real-world testing to measure effectiveness and improve design robustness.
