Aircraft Assembly Error Propagation Modeling and Coordination Error Chain Construction for Enhanced Precision

This article proposes a method based on assembly error propagation modeling and coordination error chain construction to address error issues in aircraft assembly processes. The method effectively controls and manages assembly errors by analyzing error sources and propagation paths during the aircraft assembly process, establishing an error propagation model and a coordination error chain. Specifically, the method involves the following steps:

1. Analyzing error sources: Analyzing potential error sources during aircraft assembly, including part size deviations, processing errors, assembly tool errors, etc.

2. Establishing an error propagation model: Based on error sources, an assembly error propagation model is established to analyze error propagation paths and influencing factors, calculating error contributions at each assembly stage.

3. Constructing a coordination error chain: Based on the error propagation model, a coordination error chain is constructed, encompassing various measures taken during assembly to minimize error propagation and impact. For instance, optimizing assembly sequences, controlling assembly tool precision, and employing suitable assembly fixtures.

4. Implementing error control: Effective control and management of assembly errors are achieved by implementing the measures outlined in the coordination error chain, ensuring aircraft quality and safety.

The application of this method enhances aircraft assembly precision and efficiency, reducing the number and impact of assembly errors, thereby guaranteeing aircraft reliability and safety.
