Abstract

Abstract: This paper discusses the failure mode of structure under complex working conditions of oil drilling. The method of selecting the main failure mode of directional probe framework under the condition of vibration is deduced. The calculation of the vibration resistance reliability for the framework of directional probe is simplified. The anti-vibration reliability index of directional probe framework is calculated by an example in this paper. The influence of machining error and additional quality on the vibration resistance reliability of directional probe framework are also analyzed. The results show that the main failure modes of the directional probe framework are different with different additional mass. Therefore, the research results have certain design guidance significance.
