Push System, Uncertainty Analysis, Six Sigma Module, Reliability AnalysisAbstract
The push system of the microsphere focusing logging tool is an important moving mechanism of this type of logging tool. The push system will periodically bear large loads under working conditions and is prone to stress concentration. Its structural strength and reliability are related to the logging accuracy. and even the success or failure of the logging mission. Based on ANSYS workbench software, this paper first conducts modeling and static simulation of the microsphere focusing logging tool push system under working conditions, and secondly conducts uncertainty analysis on the maximum equivalent stress of the push system based on the simulation results. , Finally, based on the analysis results, the six sigma module was used to conduct a reliability analysis of the pushing system, and the structural strength reliability of the microsphere focusing logging tool pushing system was given through the probability distribution table obtained from the analysis. The analysis results show that the maximum equivalent stress occurs on the link arm of the pushing system under working conditions. Under the current working condition, the link arm strength of the pushing system is highly reliable and can meet daily logging needs.
