Research on Detection Method of Loose Bolts Tower Under Vibration Conditions

With the continuous improvement of computing capability, it possible to establish a detailed solid model of bolted connection structure and directly calculate the time-domain response of the structure under load. The solid model method, because it can reflect both macroscopic characteristics such as stiffness and deformation, and microscopic characteristics such as friction and slippage, is an important link from experimental facts and phenomenological methods to theoretical framework, and has important research significance.
