Abstract: In order to solve the problem of consistency between geometric information and technical information of MBD models in the design change process, a parametric method of MBD models is proposed. Firstly, the parameterization of MBD models is decomposed to those problems about geometric information, technical information and geometric-technical information. Secondly, the concept of Hybrid-Attributed Adjacency Graph（H-AAG） is proposed to express the structural and numerical relations among elements in MBD models. H-AAG is constructed by defining the nodes and edges. Thirdly, a method of MBD model parameterization is proposed and the MBD model change decision table is generated for the designers. Finally, a pin part of a certain type aircraft is used as an example to verify the effectiveness of the proposed method.
