The Research on Reliability of Drilling Automatic Sampling Mechanism

Abstract:

This article put forward drilling mechanism reliability evaluation method on the lunar surface based on probability theory of stress-strength according to the characteristic, working environment and force condition of drilling automatic sampling mechanism on the lunar surface, ABAQUS was utilized to model and simulate the drilling automatic sampling mechanisms, and the dynamic distribution of stress of drilling automatic sampling mechanisms was obtained. According to analytic system reliability and the reliability evaluation reasonably, the optimization allocation to the use of material and system reliability can be realized.
