Contact Nonlinear FE Analysis and Intensity Evaluation of Double-Cone Seal

In the paper double-cone seal of ammonia converter is analyzed by means of Finite element methods.The contact nonlinear FEM is adopted to simulate the process of double-cone seal in the pretension condition and the operation condition.The curve of contact stress versus time is generated based on the simulation.The stress distribution of plat head and seal ring identified that the standard radial clearance design in GB150-2011 is reasonable and can meet the seal requirements.The deformation and stress distribution evaluation of the entire double-cone seal is further conducted.Bolts load obtained from analysis result and theoretical value of the two conditions are in good agreement, and the deviation is less than 2.1%, which proves that the simulation result is reliable.
