GROUND DYNAMIC BALL VISCOMETER Russian patent published in 2022 - IPC G01N11/10 

FIELD: measuring technology.

SUBSTANCE: invention relates to the field of measuring technology and is intended for the study of the viscosity of non-cohesive soils under vibration effects by moving the ball in the sample under study. The ground dynamic ball viscometer consists of a working chamber fixed on a vibration platform and having a cavity for placing the medium under study, a ball placed in the medium under study and connected to the load by means of a thread passed through the opening of the working chamber, a movable rigid lid, the dimensions of which ensure its movement inside the working chamber without being supported by the side and end walls of the chamber, groups of springs resting on one side against a movable rigid lid, and on the other side against fasteners having a threaded hole connected to through drawing rods, having an external thread, which are connected at the other end to the bottom of the working chamber, as well as an accelerometer with the possibility of connecting a computer to it, located outside the working chamber in the center of its side wall. The size of the ball is no less than 20 mm, the width and height of the chamber is no less than 1:10 to the size of the ball, and the longitudinal size of the chamber is no less than 1:25 to the size of the ball.

EFFECT: improving the accuracy of measuring the viscosity of dispersed materials under the action of vibrations, providing the possibility of measuring viscosity at large values of vibration acceleration without disturbing the continuity of the medium under study, providing the possibility of measuring viscosity at various values of static stress in the sandy soil under study, as well as direct measurement of the actual vibration parameters (frequency and vibration acceleration).
