A measuring device and method for centrifuge swing leftover angle

Abstract

The invention discloses a measuring device and method for centrifuge swing leftover angle. By placing the measuring device on the hanging basket of the centrifuge, the measuring device arranges pore pressure sensors near the bottom panel, and measures the pore pressure sensors arranged at different positions. The pore pressure at different positions at the same bottom surface position, and then observe the liquid level changes at different positions through the arranged cameras, and then measure and calculate the swing legacy angle at this position. The method of the invention can measure the leftover angle of swing of the suspension basket of the geotechnical centrifuge, breaks through the problem of measuring the inclination angle under the supergravity state, has strong operability, low cost, and is easy to popularize and apply to geotechnical centrifuge equipment.

Description

technical field [0001] The invention relates to a measuring device and method for centrifuge swing leftover angle, which belongs to the technical field of centrifugal test. The swinging leftover angle of centrifuge hanging basket can be measured by the device and method. Background technique [0002] Geotechnical centrifuges are indispensable scientific research equipment for the development of the geotechnical construction industry, especially large-scale civil buildings, water conservancy bridges, and most of them need to use geotechnical centrifuges to do some preliminary model tests. The geotechnical centrifuge uses a large motor to drive the hanging basket to move in a circle around the bearing, and uses centrifugal force to simulate supergravity. As the set acceleration G value of the centrifuge increases, the rotational speed of the centrifuge increases continuously, and the upward swing angle of the hanging basket increases continuously. [0003] At present, most do...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many inclinometers, but most of them can only work under constant gravity, and few can work normally under overweight

And once it exceeds a very high supergravity (16g), it will fail by itself, and there is no way to complete the task of measuring the hem angle with a high G value.

Based on the current lack of inclination measuring equipment under supergravity conditions, the present invention provides a new measurement method, which can meet the measurement of the swing angle of the geotechnical centrifuge basket under high supergravity conditions
