Research Status and Prospect of Key Technologies of Agricultural Track Chassis

In view of its advantages such as small ground pressure, good climbing Performance and flexible turning, agricultural track chassis is currently a mobile agricultural power machinery widely recognized by farmers, which has been widely used in various aspects of agricultural production such as farming, planting, field management, harvesting, transportation, and gradually developing in the direction of automation and intelligence. The development Status at home and abroad was mainly expounded from the application of agricultural track chassis, stability theory and control technology, drive System and steering technology, autonomous navigation and intelligent control technology, and agricultural track chassis — soil interaction theory. The application progress of stable leveling, efficient transmission, smooth steering and autonomous driving in agricultural track chassis was summarized. Combined with different agricultural Operations, the application characteristics of agricultural track chassis in related fields were illustrated. At last, according to the current and future needs of agricultural track chassis in China, the future development direction of agricultural track chassis was prospected from the aspects of strengthening the optimization of high-stability Walking System, creating efficient transmission and flexible steering System, overcoming the teehnology of autonomous driving and intelligent control, and researehing the basie theory of track — soil System. The research result can provide a good reference for the future technical research of agricultural track chassis. © 2024 Chinese Society of Agricultural Machinery. All rights reserved.
