履带式农业装备黏土壤土通过性研究

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.
