Force Analysis and Structural Improvement of Mining Hydraulic Support Base
Taking ZY7800-15/30 D hydraulic support as the research object,and with the help of Ansys finite element software,the force analysis under different working conditions was carried out,and the root cause of stress concentration was found.By increasing the thickness of the overpass steel plate and cutting the thickness of the side plate and ribs,the base structure of the hydraulic bracket was optimised,and the maximum stress was reduced by nearly 60％,which achieved the expected effect.Through the improvement of the hydraulic support base structure,better results have been achieved,so that the service life of the hydraulic support has increased by more than 50％,providing a guarantee for the safe production of the mine.
