We developed PhysFormer, a physics-constrained Transformer model that integrates 1D convolution and attention mechanisms, achieving accurate pressure reconstruction (RMSE = 0.035 bar). For forecasting, PhysFormer-Predict was designed using sliding windows and crankshaft encoding, enabling precise future pressure prediction (RMSE = 0.96 bar). To bypass error accumulation from traditional pressure differentiation, an end-to-end model (PhysHRRFormer-Predict) was built with dynamic frequency attention, directly predicting HRR from vibrations and reducing RMSE by 57% versus stepwise methods. This work provides a cost-effective, reliable single-sensor solution, significantly advancing real-time combustion monitoring for digital twins.]]> https://www.frontiersin.org/articles/10.3389/fmech.2026.1838542 https://www.frontiersin.org/articles/10.3389/fmech.2026.1838542 2026-07-07T00:00:00Z Original Research Mingli LiZhu Yuan https://www.frontiersin.org/articles/10.3389/fmech.2026.1889702 https://www.frontiersin.org/articles/10.3389/fmech.2026.1889702 2026-07-03T00:00:00Z Mini Review Yingshuai LiuXintong LiXiaobo HuangShuanglong XuJianwei Tan 3.5 kW/kg), greater efficiency (>92%), and reduced volume. Second, component-level structural design is analyzed in depth, covering permanent magnet synchronous motor (PMSM) hair-pin winding technologies, silicon carbide (SiC)-based inverter topologies, and multi-stage reducer configurations. Third, system-level integration challenges—including dual-circuit thermal management, electromagnetic compatibility (EMC) under high-frequency switching, and structural reliability validated through CAE-based modal and random vibration analysis—are critically discussed. Fourth, future trends toward domain-controller fusion, intelligent voltage boosting, and bifurcated ecosystem strategies between original equipment manufacturers (OEMs) and Tier 1 suppliers are explored. The review employs a systematic search across Web of Science, IEEE Xplore, and ScienceDirect databases (2012–2025), using keyword-based retrieval with inclusion criteria requiring relevance to structural design, system-level integration, and quantitative performance metrics, to synthesize findings from 30 peer-reviewed journal articles, offering a holistic perspective on how electromagnetic, thermal, mechanical, and control domain synergies define the next-generation of NEV powertrains. This work serves as a reference for researchers and engineers engaged in the structural optimization of highly integrated electric drive systems.]]> https://www.frontiersin.org/articles/10.3389/fmech.2026.1875839 https://www.frontiersin.org/articles/10.3389/fmech.2026.1875839 2026-07-03T00:00:00Z Original Research Sinnappadass MuniyappanI.
