A Physics-based Approach to Reliability Modelling of the Shafting of Double-axis Turntable
2022 International Conference on Sensing, Measurement & Data Analytics in the era of Artificial Intelligence (ICSMD)(2022)
摘要
To comprehensively consider the effects of physical properties, external conditions, degradation and uncertainties on the reliability of the shafting of double-axis turntable, a physics-based belief reliability model of the shafting of double-axis turntable is proposed based on the reliability science principles. A simulation case for the shafting of double-axis turntable is conducted to apply the proposed model and the sensitivity analysis is implemented. The results demonstrate that the hardness has a most significant influence on the margin degradation process and the uncertainty from the variations of the contact stress of the azimuth axis significantly affects the reliability and the confidential interval range of the margin. The conclusions of sensitivity analysis can provide theoretical reference for the product design and using processes.
