摘要

摘要: 为满足当前中国探月任务中的“堪测、采、建”战略规划，获取更加贴近真实的月壤物理力学特性，考虑月壤颗粒形状的影响，结合嫦娥五号探月任务中的月壤颗粒图像，将月壤粒形特征与颗粒级配联系起来，提出考虑中国月壤粒形特征的离散元数值模拟方法。首先，基于嫦娥五号探月任务获取的部分月壤颗粒图像，对颗粒的形状特征及尺寸信息进行提取，依据其球度特征将月壤的颗粒形态分为6类，并同月壤颗粒的粒形特征与颗粒尺寸建立对应关系；其次，结合本团队开发的三维离散元月壤接触模型，引入形状参数用以表征月壤颗粒的抗转动能力，进而在离散元中考虑月壤颗粒的粒形特征，最终建立考虑中国月壤粒形特征的离散元数值模型；通过与已知月壤试验结果的对比表明，该方法可将月壤颗粒形状的可变性直接映射到离散元中。在此基础上，通过与不考虑粒形特征的数值样进行对比，探究考虑月壤粒形特征的优势。结果表明：含嫦娥五号月壤粒形特征的离散元数值模型可以有效捕捉月壤力学行为的主要特征，为开展月球资源勘探及开发利用研究提供基础。

Abstract: To align with the current strategic planning of "survey, mining, and development" in China's lunar exploration mission, and to obtain more accurate physical and mechanical properties of lunar regolith, this study focuses on the influences of lunar regolith particle shape based on particle images from the lunar regolith of the Chang'E-5 mission. A discrete element numerical simulation method that considers lunar regolith particle morphology is proposed by linking particle shape characteristics with gradation. Initially, the shape characteristics and size information of the particles are extracted from the lunar regolith images. The particles are subsequently categorized into six groups based on their sphericity, establishing the corresponding relationships. Secondly, the study utilizes a three-dimensional (3D) lunar regolith contact model and calculates rolling and twisting resistances at inter-particle contact by incorporating shape parameters to account for lunar particle shape effects. Subsequently, the model considers particle size characteristics within the discrete element analysis. Ultimately, a discrete element numerical model that incorporates the particle shape characteristics of the China's lunar regolith is developed. Comparison with the results of Apollo lunar regolith laboratory tests reveals that the variability of grain shape in lunar particles can be directly incorporated into the discrete model. Additionally, the benefits of considering the grain shape characteristics of lunar regolith are discussed in comparison to numerical samples that neglect the characteristics. The results show that the proposed method can effectively capture the main characteristics of the mechanical behavior of lunar regolith, and provide a basis for the lunar resource exploration and exploitation methods.
