Non-destructive Inspection Model Generation for Composite Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Generating a non-destructive inspection model for composite parts is a complex and resource-intensive process, especially in aerospace applications, where physical internal inspection often requires destruction of the part, and existing methods struggle to efficiently utilize design model data for predicting acoustic wave responses.
Innovation Solution
A method and system that analyze design model files to determine properties of composite parts, such as ply and interply descriptions, to generate a non-destructive inspection model, using a computing platform with a processor and memory, including modules for design model file analysis and non-destructive inspection model generation, which enables the creation of accurate models for simulating acoustic wave propagation without physical testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical internal inspection methods are used on composite parts, then inspection can be performed, but the part must be destroyed
Solution Approach 1:
The patent creates a digital copy (virtual model) of the composite part from its design model, which can be inspected repeatedly without affecting the physical part. This virtual model replicates the acoustic wave propagation characteristics, allowing non-destructive inspection simulation and eliminating the need for destructive physical testing.
2Reliability
If traditional non-destructive inspection model generation methods are used, then inspection models can be created, but the process is complex and resource intensive
Solution Approach 1:
The patent performs preliminary actions by utilizing the design model data that already exists from the manufacturing process. By extracting material properties, geometry, and layup information from the pre-existing design model, the system eliminates the need for time-consuming physical measurements and setup, significantly accelerating the inspection model generation process while maintaining accuracy.
3Loss of information
If design model data is not utilized for inspection model generation, then inspection models can be created using physical testing, but rich design data is wasted
Solution Approach 1:
The patent makes the design model serve multiple functions: it is used both for manufacturing the composite part and for generating the non-destructive inspection model. By extracting relevant information (material properties, geometry, layup sequence) from the design model, the system eliminates the need for separate physical characterization processes, reducing complexity while maximizing the utility of existing design data.
