Abstract

With the fast technology development, space mechanisms have become a complex mechatronic system. Cascading and coupling reliability problems of space mechanisms have been increasingly complex and cannot match the assumptions of static state, independence and large samples of traditional reliability theory with prominent characters of multi-factor, multi-level and coupling. Based on Coupling and Hierarchies Bayesian Networks (CHBN), this paper establishes cascading and coupling reliability model of space mechanisms with the introduction of dynamic response and clearance with inter-level and intra-level failures in systems. By using hierarchies theory and uncertainty propagation directed graph thought, according to product components of system and its hierarchical relationship with inter-level and intra-level failures, this paper describes cascading and coupling reliability issues of space mechanisms in detail and works the problems that traditional reliability modeling methods cannot accurately describe and estimate results easily. In the last, the proposed reliability modeling method is verified by a two-axis-position mechanism.
