摘要	The non-probabilistic method was proposed according to the distribution pattern of uncertain parameters inaccurately acquired from the reliability analysis. Interval model was used to describe the uncertain parameters, and based on non-probabilistic set-based stress-strength interference theory, the non-probabilistic reliability index was studied under different conditions. Meanwhile the reliability index under probabilistic model of a propeller shaft was compared with that of interval model and the changes of the non-probabilistic reliability were also observed with different deviation of the uncertain parameters. The result shows that when the outer diameter of the propeller shaft is 50 mm the structure was reliable under probabilistic model and interval model, but when the outer diameter is 48 mm the probabilistic and non-probabilistic reliabilities were 0.999803 and 0.982110, respectively. Therefore, conclusions were consistent under probabilistic and interval models, but the non-probabilistic method was more conservative. Meanwhile with increase of deviation for the uncertain parameters, the non-probabilistic reliability of propeller shaft gradually reduced. Therefore, the strength of deviation is the main factor affecting non-probabilistic reliability, while the torque of deviation is the least. Consequently the reliability of propeller shaft increased with the increase of the thickness and decrease of the deviation of uncertain parameters. The method of non-probabilistic reliability analysis was feasible.
