To address the problems of large curing deformation and residual stress in the rotating shell structures of carbon fiber composites applied in the aerospace field，this paper established a three-dimensional finite element model for analyzing the curing process of composite rotating shell structures，and predicted the curing deformation and residual stress of the structures.A method for the optimal control of curing process and post-curing process parameters was proposed，and the curing process curve of the structures was optimized and designed.Under the standard curing system，the predicted results of the maximum residual stress and curing deformation of the composite shell structure are 409.12 MPa and 335.9 μm，respectively.Based on the established finite element model，the influences of various process parameters on the maximum residual stress and curing deformation of the structure are analyzed.Furthermore，combined with the analysis results of each process parameter， the combined optimization of curing process parameters is completed.Under the conditions of the obtained optimal curing process scheme，the maximum residual stress and deformation of the structure are 325.11 MPa and 295.1 μm，respectively，which are reduced by 20.53% and 13.21% compared with the standard curing system.
