ABSTRACT: In order to study the dynamic characteristics of spring-tooth vibration sub-soiling shovel in subsoiling process and its influences to subsoiling performance, this paper sets spring-tooth sub-soiling shovel and rigidityity sub-soiling shovel as study objects. Through soil test trolley ,vibration tester and other equipment and by applying mechanical vibration principle and signal testing technology, it has tested the vibration and traction of the two kinds of sub-soiling shovels. Through the contrast test and data processing it finds out that: the vibration of spring-tooth sub-soiling shovel belongs to random forced vibration. The main causes of its vibration is the constant changing of soil resistance. At the near surface area, compared with rigidityity sub-soiling shovel the traction resistance of spring-tooth sub-soiling shovel decreases by 9.95% and subsoiling specific resistance decreases by 14.52%, which offers a better resistance reduction effect.

Keywords : Sub-Soiling shovel; Vibration; Spring tooth; Dynamic characteristics.
