摘要：

Drive wheel is an important transmission component in a tracked vehicle chassis system, its strength has a certain uncertainty and is degenerative with time in actual operation process. Here, Gamma random process was used to describe the strength degradation process of mechanical components. Matrix differential method was used to derive sensitivity calculation formulas for mean and variance of mechanical components' random variables. Taking drive wheel of a tracked vehicle as an example, the proposed method was verified. The results showed that the proposed method can effectively solve the sensitivity analysis problem for the reliability of mechanical components with strength degradation; the study results can be extended to the related machinery reliability optimal design fields with some practical significance. © 2018, Editorial Office of Journal of Vibration and Shock.
