“…With the accumulation of FEA cases, how to identify the most similar cases from these solved cases has become one of the key technologies in the CBR-based FEA system. An FEA case mainly includes the data of the FEA modeling process that consists of the FEA task, FEA solution, FEA model, and FEA result (Saarelainen et al, 2014; Joshi, 2004). The FEA task is the textual description of the analysis problem, which includes the mechanical device classification, aim of the analysis, contact pair identification, material properties definition, and contact problem properties definition.…”

“…The description of FEA tasks is generally in the form of natural language, which is particularly applicable to large-scale enterprises where the process of design and analysis requires the collaboration of several departments (Saarelainen et al, 2014; Nosenzo et al, 2014), and to the engineering field where the analysis results need to be checked, such as pressure vessels (Gupta and Vora, 2014; Niranjana et al, 2018). To form a representation that can be processed by a computer, first, an ontology of the FEA modeling process is constructed, then text processing technology is used to obtain the entities of the task description, and finally, the ontology is instantiated to form a structured description of the FEA task based on the entities.…”

The widespread use of finite-element analysis (FEA) in industry has led to a large accumulation of cases. Leveraging past FEA cases can improve accuracy and efficiency in analyzing new complex tasks. However, current engineering case retrieval methods struggle to measure semantic similarity between FEA cases. Therefore, this article proposed a method for measuring the similarity of FEA cases based on ontology semantic trees. FEA tasks are used as indexes for FEA cases, and an FEA case ontology is constructed. By using named entity recognition technology, pivotal entities are extracted from FEA tasks, enabling the instantiation of the FEA case ontology and the creation of a structured representation for FEA cases. Then, a multitree algorithm is used to calculate the semantic similarity of FEA cases. Finally, the correctness of this method was confirmed through an FEA case retrieval experiment on a pressure vessel. The experimental results clearly showed that the approach outlined in this article aligns more closely with expert ratings, providing strong validation for its effectiveness.

“…In addition to production data, simulating the products also creates valuable data for the extension and refinement of the platform. (Saarelainen, Buda et al 2014) addresses the open loops where there is a lack of feedback of simulation data. The authors have investigated by interviews what the main drivers are for closing the open loops.…”

Computer simulations play an important role for evaluating designs in an early stages leading to that more informed decisions can be taken and thereby reducing the risk of costly re-design. In this paper, a platform currently in operation at aeronautical company for doing extensive automated multiobjective design parameter studies on conceptual designs of aircraft engine components is studied. In the paper, an extension of the capability of the platform into making a rule-based evaluation of the welding manufacturability of the conceptual designs is proposed. The extension is tested by a prototype system at the air-craft manufacturer showing the relation between the design parameters and the manufacturability of the components. The results are presented as a manufacturability index showing what trade-offs with other performance criteria of the engine that can be made. It is shown that the manufacturability evaluation can be integrated in the knowledge value stream and supports a set-based concurrent engineering approach in the company.
