目前,对于散体颗粒物质与复杂机械系统的耦合作用研究,面临着跨尺度、计算规模庞大以及非光滑表面的接触检测困难等问题。为了探究月球车与月壤交互作用,首先对颗粒-多体耦合系统动力学建模与接触算法进行研究。分别用离散元方法(discrete element method, DEM)和多体动力学(multibody dynamics, MBD)笛卡尔方法建立了散体球形颗粒和含约束多体系统的动力学模型,并基于Hertz-Mindlin模型计算颗粒与刚体的接触力,在此基础上给出顺序耦合策略,建立了离散元和多体耦合的动力学模型。针对月球车齿状车轮的非光滑表面与颗粒之间接触检测规模庞大的问题,提出了非光滑形状物体的分区域局部检测方法,降低了局部检测的规模。通过对比圆柱体冲击颗粒的试验和仿真结果,验证了离散元-多体耦合模型的准确性。在耦合动力学建模和接触算法研究的基础上,对具有齿状车轮的月球车在月壤上行驶过程进行动力学仿真,研究不同驱动参数下的系统动力学特性以及不同轮胎形状对行驶运动的影响,研究结果表明,交错形轮齿的月球车相较直齿形轮齿前进距离多14%,前进效率较高,该研究对月球车的设计具有理论指导意义。

The emerging biomass-based epoxy vitrimers hold great potential to fulfill the requirements for sustainable development of *** the existence of dynamic chemical bonds in vitrimers often reduces both the thermal and mechanical properties of epoxy resins, it is challenging to produce recyclable epoxy vitrimers with both excellent mechanical properties and good thermal stability. Herein, a monomer 4-(((5-(hydroxymethyl)furan-2-yl)methylene)amino)phenol(FCN) containing furan ring with potential to form high density of hydrogen bonding among repeating units is designed and copolymerized with glycerol triglycidyl ether to yield epoxy resin(FCN-GTE), which intrinsically has dual hydrogen bond networks, dynamic imine structure and resultant high performance. Importantly, as compared to the BPA-GTE, the FCN-GTE exhibits significantly improved mechanical properties owing to the increased density of hydrogen bond network and physical crosslinking interaction. Furthermore, density functional theory(DFT) calculation and in situ FTIR analysis is conducted to decipher the formation mechanism of hydrogen bond network. In addition, the FCN-GTE possesses superior UV shielding, chemical degradation, and recyclability because of the existence of abundant imine bonds. Notably, the FCN-GTE-based carbon fiber composites could be completely recycled in an amine *** study provides a facile strategy for synthesizing recyclable biomass-based high-performance epoxy vitrimers and carbon fiber composites.

基于语义描述的音乐检索是根据音乐所表达的语义和对音乐的主观感受,查找或发现音乐的一种方式。一个典型的基于语义描述的检索(query by semantic description,QBSD)系统被定义为有监督的多类别标记(supervised multi-class labeling,SML)模型,通过使用语义相关标签来标记未知,将音乐映射到一个"语义空间",从而克服语义鸿沟问题。在SML模型基础上,提出将示例音乐作为检索条件,通过对音乐语义的标注将检索示例映射到语义空间,然后在标记后的数据库中,返回语义相似的音乐。并且采用深度学习算法,设计了多类别标记模型。实验表明该模型能够满足用户基于语义音乐检索的基本需要。
