Strength Analysis of ZC20000/34/68 Superhydrostatic Hydraulic Support under Different Working Conditions in Coal Mine
In order to further explore the possible optimization path of the super-static hydraulic support,the ZC20000/34/68 super-static hydraulic support is taken as the research object,and on the basis of three-dimensional modelling,the strength analysis is carried out by comprehensively considering the various unfavorable working conditions,with emphasis on the analysis of its stress distribution,and the preliminary optimization path of the hydraulic support is explored on the basis of the results of the simulation analysis.On this basis,the fatigue life of this type of super-static hydraulic support is further analyzed,and more targeted optimization measures are proposed for some parts with low fatigue life,in order to provide reference for the subsequent optimization work.
