4results about How to "Enable continuous testing" patented technology

This invention belongs to the field of sensor and machine learning technology. It proposes a simulation test system and method for the mechanical properties of rock joints based on the principle of equivalent body force field. The main components include: constructing a geomechanical similarity model based on the principle of equivalent body force field, including a base and a rock mass physical model. When the base moves relative to the interface of the rock mass physical model, the friction between the base and the bottom surface of the rock mass physical model generates uniformly distributed shear stress, which generates equivalent body force intensity inside the rock mass physical model; collecting multidimensional sensing data when the base moves relative to the interface of the rock mass physical model; automatically identifying the rock mass joint extension trajectory based on the multidimensional sensing data and using an improved U-Net machine learning model; obtaining displacement field data through an improved particle image velocimetry combined with an optical flow algorithm; using a Bayesian inference inversion model to invert the mechanical parameters of the joint surface; and evaluating the uncertainty of the inversion results using the Markov chain Monte Carlo method.
