The finite element method is used to analyze the nonlinear contact of the wormlike sealing ring in Dn1160 high-pressure sintering furnace. Using Ansys 14.5 to simulate the Von Mises stress under different static. Through the contact deformation, contact stress and the distribution of the stress, the easily crack position and service life of the wormlike sealing ring can be reflected. Then discuss the effects of different system pressure, notch radius, seal clearance, friction coefficient on the sealing performance. So as to evaluate the sealing performance of the wormlike sealing ring.

The finite element analysis software ANSYS was used to propose a parametric model of the quickopening structure with toothlocked sintering furnace cover. The structure design was optimized by using weight parameter as the objective function and using allowable stress as constraints. Based on the optimal sizes the intensity design requirements were met and the weight of the structure was reduced effectively. Data reference for the similar quickopening structure design was given in this paper.

The grid of the quickopening clamp structure on the pressure sintering furnace was meshed by utilizing HyperMesh software, and the nonlinear contact analysis for the quickopening structure was achieved by ANSYS contact element, then the third strength equivalent stress and deformation of the quickopening structure under the designed pressure were obtained. The analyses of the furnace lid, body and clamp were accomplished. The stress intensity on the dangerous crosssection was evaluated according to JB4732—1995 [WTBX]Steel pressure vessels——analyze design standard[WTBZ]. The analysis results indicate that the intensity requirement is satisfied. 
