试验验证和数值仿真是评估结构强度的两种典型方法,然而基于离散传感器的试验验证方法难以保证结构应力监测覆盖度,数值仿真方法又因为对物理实体的简化和理想化处理而导致应力结果精度不足,如何综合利用两种强度评估方法的优势并进行数据融合以实现结构应力场监测是一个具有挑战性的问题。提出一种面向结构静力试验监测的数字孪生(DT-SSTM)方法,可获得高精度的结构静力试验数字孪生模型,以实现结构应力场的实时监测与强度评估。DT-SSTM方法包括离线、在线2个阶段。离线阶段,采用梯度提升树(GBDT)算法对仿真数据进行训练,建立预训练模型。在线阶段,基于集成学习理论,采用Stacking算法对试验数据响应值与预训练模型响应值之间的残差进行训练并建立残差模型。通过叠加预训练模型与残差模型实现多源数据融合,建立高精度的数字孪生模型。最后,开展了开口矩形壁板轴向拉伸试验来验证DT-SSTM方法的有效性。结果表明,DT-SSTM方法能够建立高精度的结构静力试验数字孪生模型,且相比同类数据融合方法具有更高的全局、局部预测精度以及融合效率,为结构应力场实时监测提供了一种新颖的解决方案。

Deformation can change the transition pathway of materials under high pressure, thus significantly affects physical and chemical properties of matters. However, accurate pressure calibration under deformation is challenging and thereby causes relatively large pressure uncertainties in deformation experiments, resulting in the synthesis of complex multiphase materials. Here, pressure generations of three types of deformation assemblies were well calibrated in a Walker-type large-volume press (LVP) by electrical resistance measurements combined with finite element simulations (FESs). Hard Al2O3 or diamond pistons in shear and uniaxial deformation assemblies significantly increase the efficiency of pressure generation compared with the conventional quasi-hydrostatic assembly. The uniaxial deformation assembly using flat diamond pistons possesses the highest efficiency in these deformation assemblies. This finding is further confirmed by stress distribution analysis based on FESs. With this deformation assembly, we found shear can effectively promote the transformation of C60 into diamond under high pressure and realized the synthesis of phase-pure diamond at relatively moderate pressure and temperature conditions. The present developed techniques will help improve pressure efficiencies in LVP and explore the new physical and chemical properties of materials under deformation in both science and technology.
