Firing accuracy is an important index in the performance evaluation of electromagnetic railgun (EMRG). Based on a Six-DOF (degree of freedom) computer model of exterior trajectory, Sobol’s method, a global sensitivity analysis approach, is utilized to analyse the influence of multiply model inputs with uncertainty on the strike accuracy of EMRG projectile. The method utilizes the firing data error and the dispersion error as the firing accuracy assessment factors of the projectile, and the input data are sampled based on Latin Hypercube Sampling (LHS). Furthermore, an example is provided, in which Sobol’s method is applied in the analysis and calculation of the exterior trajectory. First-order sensitivity and total sensitivity of each factor are obtained, and then we identify the impact mechanism and interaction of different input parameters having on firing accuracy. Finally the results verify that the method is feasible and effective in the process of performance analysis of EMRG exterior trajectory.
