摘要： 针对黏土壤土地面履带式农业装备的通过性问题，采集黏土壤土的土壤样本，进行黏土壤土的力学特性试验，获取黏土壤土力学特性关键参数；采集黏土壤土地面高程信息，构建地面不平度功率谱密度函数。基于黏土壤土的力学特性及地面高程信息，结合某履带式农业装备具体结构参数，构建履带式农业装备黏土壤土地面通过性的仿真模型，并以第一负重轮的沉陷量作为评价指标，采用仿真分析和试验验证相结合的方法研究履带式农业装备在该黏土壤土地面上的越野通过性。研究结果表明，履带式农业装备第一负重轮的最大沉陷量仿真结果和试验结果分别为135mm、170mm，均小于履带式农业装备的离地间隙值280mm，该履带式农业装备在该黏土壤土地面上具有良好的通过性。该研究成果具有较强的工程实践意义，为履带式农业装备的设计研发和优化升级提供了理论指导和技术支撑。

Abstract: This study addresses the issue of the transportability of crawler agricultural equipment on clay loam. Soil samples of clay loam were collected, and mechanical properties were conducted to obtain the key parameters of mechanical properties. Ground elevation information was also collected and used to build a power spectral density function of ground roughness. Based on the mechanical properties of clay loam and ground elevation information, combined with specific structural parameters of the crawler agricultural equipment, a ground transportability simulation model of crawler agricultural equipment on clay loam was constructed. The settlement amount of the first road wheel was taken as the evaluation index, and the crosscountry transportability of crawler agricultural equipment on clay loam was studied by simulation analysis and experimental verification. The results showed that the maximum settlement of the first road wheel of crawler agricultural equipment was 135 mm and 170 mm, respectively, both of which were smaller than the ground clearance value of 280 mm for crawler agricultural equipment. Thus, the crawler agricultural equipment demonstrated good pass transportability on clay loam ground. The research results have strong practical significance and provide theoretical guidance and technical support for designing and optimizing crawler agricultural equipment.
