Title:
STATIC PRESSURE VIBRATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/121285
Kind Code:
A1
Abstract:
A static pressure vibration system, comprising: a hydraulic cylinder (40), wherein a static pressure cavity (570) and a dynamic load cavity (580) are formed in the hydraulic cylinder (40), the static pressure cavity (570) is provided with a first piston rod (540), the dynamic load cavity (580) is provided with a second piston rod (550), the first piston rod (540) is configured to output a static load to a test surface, the output end of the second piston rod (550) is superimposed with the output end of the first piston rod (540), and the second piston rod (550) is configured to output a vibration impact force to the test surface; a first oil supply device, which is configured to provide stable oil pressure to the static pressure cavity (570); and a second oil supply device, which is configured to supply oil to the dynamic load cavity (580) according to a set frequency. The static pressure vibration system of the double-acting hydraulic cylinder (40) is able to simultaneously apply a static load and a vibration impact force to a test surface, so that the test surface can be subject to a high-frequency vibration impact force under static pressure conditions so as to test the actual bearing capacity of soil under the action of dynamic and static loads, thereby providing a solution for the high-frequency vibration test of the soil.
