Compared with traditional aero-engine assembly methods, flexible assembly tooling is more rapid, efficient and accurate.Based on the features of aero-engine assembly, this paper finishes a configuration on flexible assembly tooling and makes analysis on positional accuracy.And it builds the velocity jacobin matrix and error model according to its kinematics equation.We conduct the case simulation referring to the size of assembly foundations of aero-engine, and determine the structural parameters with the changing ones and their position.The method in this paper makes great sense in the design of aero-engine assembly and the positional accuracy of mobile platform, providing the theoretical basis for the process and assemble of flexible tooling.
