Since it is often appeared that connected-mold bearing FC208 rupture of roller foam machine in the production progress of a domestic company. A newly solve project on rupture of connected-mold bearing of roller foam machine based on finite element (FE) theory is put forward. All campaign process of this kind of machine is carried on mechanical analysis, and the maximum load force of bearing is calculated. FE models of FC208 and FC209 bearing are set up using ABAQUS software. The related simulation and analysis are conducted and force conditions of both components are compared with. The result of stress value is FC209 bearing is less than FC208 bearing. FC209 bearing is used in seven-positions rotating equipment made by ourselves in the company's No.40 # shop. The self-made equipment is running steady and reasonability of the improved design is proved.

The feeding crossbeam on the automatic aluminous-winding machine plays a supporting role in the preparation process of feeding pipe, the deformation of the feeding crossbeam have a direct impact on mechanical accuracy, it is difficult problem in model design, which is how to design a reasonable structure and make the crossbeam meets the requirements of strength and stiffness, as well achieve lightweight design. This article considers the complex force of crossbeam, and bases on the principle of virtual work and finite element theory, using ANASYS software to make a finite element model, the relation curves of the stress and the strain under the maximum load are summarized and the stress concentration area is found, The current study provides more reliable results to improve design.

Trough roller is an important component part on belt conveyor, the carrying capacity of the roller is a basis of belt conveyor. The calculation principle and method of material’s cross section area is deduced in the thesis, and mechanical analysis of the trough roller is carried out based on that, in results, the static load of it is calculated. The finite element model of the trough roller is set up by Simulation /Works software, and then the stress and deformation results of it is clear through finite element statics calculation and analysis. Based on this thesis, some valuable basis and reference are offered to trough roller’s strength and stiffness design.

Abstract In this paper, a reactor core mechanical analysis method is introduced to provide a tool to calculate the reactivity effect of the fuel subassembly displacement in the reactor core which is an important problem for reactor types such as the Sodium-cooled Fast Reactor (SFR). The presented method relies on the following two main steps: 1) Core deformation calculation through a Computer-Aided Design (CAD) based finite element solver and 2) Static neutronic simulation on the original undeformed and deformed core models with a Mode Carlo code to quantify the reactivity effect. The technique makes it possible to accurately simulate the deformed geometry of the reactor core and to use this deformed shape model directly in the neutronic analysis. The paper includes the verification process which was conducted to compare the accuracy of the finite element solver to the theoretical solutions regarding the deformation of a hexagonal subassembly. Moreover, the neutronic calculation accuracy has been demonstrated. Following this, a validation work has been performed on the Phenix Sodium-cooled Fast Reactor based on the data obtained from previous, end-of-life test, experimental set-up. This procedure proved the accuracy of the presented methodology for both the verification and the validation cases, giving the capability to assess the reactivity effect of a non-uniform core deformation in an SFR.

Cone is one part of a packer. To understand the seal effectiveness of the packer, mechanical analysis must be made for it. The finite element model of packer is set up and packer minimum setting load changes are calculated under different climb angle of cone. Results show that reduce the cone angle of climb can make the packer sealing load significantly lower.The calculation results provide the theoretical basis for the real operation.

With the increasing of the quantity of the tunnel, more and more attentions have been paid to the tunnel destruction induced by earthquake. Based on the software of finite element, the finite element model for deeply buried tunnel have been set up; and the responses about different rigidity of tunnel lining under seismic dynamic load has been analyzed by using elastic finite element theory. The conclusions have been drawn that the change of seismic responses by increasing rigidity of tunnel lining is unobvious, and the method using increasing rigidity of tunnel lining to reduce the seismic responses of tunnel is uneconomical.

Based on the finite element theory of dynamic explicit, the technology of multi-point forming was applied to tube forming. The process of tube multi-point forming was simulated by ABAQUS software. It is used to study the behavior of forming force under different wall thicknesses and materials for manufacturing tube. It has been found that when the curvature radius is set at 1.0m, the forming force gradually becomes larger as the wall thickness of the tube increases. The careful selection of materials is beneficial to controlling forming force. Due to the technology of mass scaling, the ultimate forming force is not the maximum forming force in the process of simulation forming. However, the ultimate forming force can be used to select the multi-point forming equipment.
