本研究旨在開發一套結合數位孿生與深度學習之啟動機動力傳動模組品質檢測系統,以取代傳統仰賴人工聽診與動力計判讀的主觀檢測方式。針對實驗資料取得不易之挑戰,本研究建立啟動機之數位孿生模型,模擬正常運作條件下之多維訊號,並大量生成通過樣本以進行非監督式預訓練,進一步提升模型初始權重品質與泛化能力。同時,本研究亦制定數據標準化規範,作為未來智慧檢測應用與資料共享之基礎。
模型設計採用時序型Transformer自編碼器架構,藉由重建誤差進行異常偵測。訓練流程結合模擬資料預訓練與少量實測資料微調,並以皮爾森相關係數與穩態參數驗證模擬資料之合理性。實驗結果顯示,本系統能於有限資料下穩定辨識啟動機異常,驗證結合數位孿生與深度學習之品質檢測策略具實用性與可行性,未來可作為啟動機再製產業導入智慧檢測系統之依據。
This study aims to develop a quality inspection system for starter motor power transmission modules by integrating digital twin technology with deep learning, replacing traditional subjective methods that rely on manual auscultation and dynamometer readings. To address the challenge of limited experimental data, a digital twin model of the starter motor was constructed to simulate multi- dimensional signals under normal operating conditions, enabling the large-scale generation of pass samples for unsupervised pre-training. This approach enhances the quality of the model's initial weights and improves its generalization capability. In addition, a data standardization protocol was established to serve as a foundation for future applications in intelligent inspection and data sharing.
The model adopts a time-series Transformer autoencoder architecture, performing anomaly detection through reconstruction error. The training process combines simulated data pre-training with fine-tuning using a small amount of measured data, while the validity of the simulated data is verified through Pearson correlation coefficients and steady-state parameters. Experimental results demonstrate that the proposed system can reliably identify starter motor anomalies even under limited data conditions, confirming the practicality and feasibility of a quality inspection strategy that integrates digital twin and deep learning. This work can serve as a reference for introducing intelligent inspection systems in the starter motor remanufacturing industry.
