Structural stability analysis of underground ultra-slender oil pipes
The trackless equipment powered by diesel engine is the core equipment of metal and non-metal underground mining.How to ensure the safe and efficient transportation of diesel oil is always the key problem that plagues the safe production of mines.In this paper,several forms of underground vertical oil pipeline system and oil pipeline constraint methods are proposed.Combined with the pressure bar stability theory and ANSYS modeling analysis,the instability analysis,thermal stress analysis and modal analysis of ultra-thin long oil pipeline are carried out,and the structural stability of oil pipeline is comprehensively investigated.The research results can provide theoretical reference for the design of underground vertical oil pipeline system.
