Method & Evidence

AimHow can an ontology-augmented digital twin be established to accurately predict the operational lifespan of fiber-reinforced polymer structures, considering manufacturing peculiarities?
MethodSimulation and Ontology-based Knowledge Representation
ProcedureA methodology was developed to create a structural digital twin for FRP components, specifically wind turbine rotor blades. This involved numerically simulating the resin cure cycle to compute effective elastic properties and residual stresses, accounting for production imperfections. These simulated properties were then integrated into a structural finite-element model. Local wind conditions were applied to this model to determine the stress state, which was used to evaluate material fatigue and predict the component's lifetime. An ontology and knowledge graph were employed within a Jupyter-based application to manage the transfer of intermediate results across different scales and process steps.
ContextDesign and analysis of fiber-reinforced polymer (FRP) structures, particularly in the aerospace and renewable energy sectors (e.g., wind turbine blades).

Variables

IVInclusion of manufacturing imperfections (e.g., residual stresses, effective elastic properties) in the digital twin model.
DVAccuracy of the predicted operational lifespan of the FRP structure.

Strengths & Limitations

Strengths

  • +Novel integration of ontologies with digital twins for composite structures.
  • +Addresses a critical gap in accurately predicting the lifespan of FRP components.
  • +Utilizes open-source software, promoting accessibility.

Limitations

The complexity of setting up and running accurate manufacturing process simulations can be a significant barrier. Developing a comprehensive ontology requires specialized knowledge.

Reliability & validity

The validity of the digital twin's predictions relies on the accuracy of the underlying material models and manufacturing simulations. Reliability would be assessed by repeating simulations with slightly varied input parameters to check for consistent outputs.

Think critically

To what extent can the computational cost of simulating manufacturing processes be justified for less critical or lower-cost composite components?

05

Design Principles

"Model the real-world manufacturing process, not just the final idealized form, to accurately predict product performance and lifespan."

This approach allows designers and engineers to move beyond idealized models and account for real-world manufacturing variations. By simulating the impact of these imperfections on material properties and stress distribution, more reliable lifespan predictions can be made, leading to optimized designs and reduced premature failures.
