Experiment analysis on traction resistance of vibration subsoiler

A vibration subsoiler model 1SZ-460 was developed based on vibration principle in order to reduce the traction resistance. Vibration was selected as the main factor for the experimental design, and field experiments were carried out in different stubble of crop. The results showed that the groove profile width was quite different for vibration and nonvibration operations. Subsoiling operation with vibration gave an help to form the rat way to store water, and reduce soil bulk density.Traction resistance with vibration was 6.9%-17% less than that of non-vibration, and the traction resistance was also affected by the differences of soil characteristics and land coverage conditions. The results provide a reference for further study on soil subsoiling as well as mechanical structure optimization .
