Abstract
A system for loading dynamic stress on subgrade or foundation based on multi-servo channel and a control method thereof. The system comprises: connecting plate; five dynamic actuators are hinged between connecting frame and the connecting plate; four of them form 4-RPR parallel mechanism, another one is arranged in middle of the 4-RPR parallel mechanism; loading part is mounted at center under the connecting frame; and restraining plate is arranged under the loading part and freely contacts with the loading part; four static actuators are arranged between the restraining plate and the connecting plate; wherein, the static actuators and dynamic actuators are dynamic-static cooperative controlled through multi-servo channel, to simulate principal stress axes rotation effect of a soil body of subgrade or foundation The system can realize the principal stress axes rotation effect in the subgrade or foundation through dynamic-static cooperative loading and can simulate different traffic load forms.
