Based on analyzing error model of Sheet Metal Assembly, namely SMA, at home and abroad, this paper establishes the propagation model of spatial error of SMA in single station, and founds the rigid error model by differential motion theory and coordinate conversion theory. On condition of satisfying the closed form and closed force, the paper analyzes the assembly deformation errors in positioning and clamping process, connecting process and spring-back process, and sets up the spatial error model of SMA in single station, and then simulates assembly errors by using MATLAB, finally compares them with the results from CATIA-TAA, and there is a good agreement between these results. The model is of significance in the work of assembly error prediction, fixture optimization design, fixture error diagnosis and tolerance synthesis design.
