Design of real-time adjustable spherical bearing for railway bridge pre-deviation based on TRIZ theory
In response to the difficulty in adjusting the pre-deviation of spherical bearing in railway bridges,this article first applies TRIZ theory to conduct functional and causal analysis of the key issues in the existing pre-deviation adjustment methods,and finds the fundamental reason for the difficulty in pre-deviation adjustment.Secondly,TRIZ tools such as object-field models and technological contradictions are used to solve the issue,find the solution to the issue,and use the scheme evaluation model to find the most suitable solution,successfully designing a pre-deviated real-time adjustable spherical bearing.Finally,through theoretical and physical adjustment verification,it is shown that this pre-deviated real-time adjustable spherical bearing scheme is feasible,which has been successfully applied to some high-speed railway lines,effectively solving the sore points of traditional pre-deviation adjustment.It has significant implications for the practical engineering of bearing pre-deviation adjustment.
