Summary:This paper proposes a tolerance analysis method of annular surfaces considering form errors and local surface deformations. Specifically, form errors are properly considered based on skin model shapes. Local surface deformations are calculated based on a Conjugate Gradient-Fast Fourier Transform (CG-FFT) method, which is a classic Boundary Element Method (BEM). Based thereon, tolerance analysis of annular surfaces is conducted based on Monte Carlo simulation, and efficiency of the process is also demonstrated.
