  • The structural model of the cable antenna was obtained by the force density iterative method. The Gaussian distribution was used to simulate the manufacturing error and thermal deformation error. The finite element model of the cable network structure error analysis was constructed. Taking the manufacturing tolerance and working temperature as variables, the influence of structural error on the antenna surface deviation of the cable was analyzed by a specific example. And comparison was made with the profile deviation analyze caused by the analysis of the cable antenna manufacturing error with the Monte Carlo method.The results showed that the method had the accuracy and feasibility of structural error analysis, which could be used to evaluate the impact of the structural error to the antenna profile accuracy.
