Abstract

A TBM vibration damping control method based on a particle swarm optimization algorithm PSO comprises the following steps: 1, building a TBM concentration parameter dynamics model; 2, modeling each rigidity node in the TBM concentration parameter dynamics model; 3, taking the minimum TBM vibration intensity and the minimum TBM driving specific energy as targets, and building a multi-target optimization vibration damping control model; 4, using the PSO algorithm to solve the multi-target optimization vibration damping control model, comparing the real time measured vibration parameter with a theory vibration parameter calculated by the concentration parameter dynamics model, further adjusting a control parameter, related to the vibration parameter, in the multi-target optimization vibrationdamping control model; using the optimization iteration algorithm to obtain the optimal rigidity parameter and driving parameter, further adjusting the control parameter in the TBM actual operation process according to the optimal rigidity parameter and driving parameter, thus realizing optimization control of TBM vibration, and realizing the high efficiency driving target of the TBM under the low vibration level conditions.

Description

technical field [0001] The invention relates to the field of engineering machinery health management, in particular to a vibration reduction control method for hard rock tunnel boring machines (TBM) based on PSO optimization algorithms. Background technique [0002] Introduction to the Prior Art Tunnels built by full-face hard rock tunnel boring machines (Tunnel Boring Machines, TBMs) have the characteristics of good quality, high efficiency, and safety of the excavated wall, making them more and more used in rock tunnel construction . Due to the strong impact load and the influence of complex geological environment during the excavation process, the body of the TBM vibrates violently, the key components are easily damaged, and the rock breaking efficiency is low. For this reason, it is necessary to study the model of TBM's efficient excavation at lower vibration levels. [0003] The vibration problem of TBM has received extensive attention. It is necessary to study the ri...
