Abstract

Focusing on the loosening of bolt connection in the rotating mechanism under dynamic tension compression and shear combination load, virtual prototyping technology and finite element analysis method are applied in studying the failure mechanism and its influencing factors. Firstly, based on the virtual prototype technology, the load of failure bolt connection structure is extracted; secondly, the finite element method is used to analyze the influence factors of bolt number, pre-tightening, connection thickness and spring shim. The evaluation index system of digital analysis is set up to guide the improved design for the anti-loosening measures. In this thesis, the improved design and research on the bolt of a servo device rotating mechanism is taken as an example. The method of digital design and analysis is carried out, which solves the problem of bolt connection loose. The conclusion shows that the improved design is consistent with the practical engineering, and bolt connection structure is free from loosening and failure.
