TL;DR: In this paper, the authors established the fault tree analysis and fuzzy reasoning Petri net (FRPN) models of a solar array mechanical system and analyzed reliability to find mechanisms of the solar array fault.

TL;DR: In this article, a new method is proposed to analyze the dynamic reliability and parameter sensitivity of space manipulator with harmonic drive, which is suitable for reliability apportionment when the design information has not been clearly identified, particularly in early design phrase.

TL;DR: A new type of FPNs are proposed, called cloud reasoning Petri nets (CRPNs) based on the concept of interval clouds and the hybrid averaging operator, where the truth degrees of places, the certainty factors of rules, and the thresholds of transitions are represented by interval clouds.

TL;DR: In this paper, an analysis method for dynamic response and parameter sensitivity of mechanical systems is proposed with the consideration of both clearance joints and uncertainties, where elements of a revolute clearance joint are modeled as colliding bodies, where continuous contact force model and modified friction force model are employed to describe the impact-contact behavior.

TL;DR: Results show that relative errors between the theoretical and experimental results of mechanism reliability are less than 5%, demonstrating the effectiveness of the proposed method.
