Abstract:Based on the characteristics of four-tracked vehicles, the mathematical model of steady steering on firm ground was established, considering the crawler width and skid steering. The influences of the factors on the steering performance were analyzed. The virtual prototype of a four tracked vehicle was built based on the multi body dynamics software RecurDyn and the steering tests were completed. The virtual prototype simulation results accorded well with the numerical results, which verified the correction of the theoretical model.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
