The finite element model of cross simulator including supporting structure, beam, etc. was set up in the environment of ABAQUS. After the static analysis which meets the requirements, the model’s dynamic characteristics when bearing impact load was obtained using explicit method according to modal analysis results. Comparing different analysis results with technical index, it indicates that larger impact load makes the dynamic characteristics worse significantly.

The System-integrated Modular Advanced ReacTor (SMART) developed by KAERI includes components like a core, steam generators, coolant pumps, and a pressurizer inside the reactor vessel. Though the integrated structure improves the safety of the reactor, it can be excited by an earthquake and pump pulsations. It is important to identify dynamic characteristics of the reactor internals considering fluid-structure interaction caused by inner coolant for preventing damage from the excitations. Thus, the finite element model is constructed to identify dynamic characteristics and natural frequencies and mode shapes are extracted from this finite element model.

This article took the climbing formwork which constructed on the bridge at a height of 100 meters as the prototype, then established the finite element model and conducted modal analysis. The APDL language is used to load the wind load which is simulated by the Matlab programming then calculated the displacement and acceleration responses of the climbing formwork and further. The results show that the bending effect of the climbing formwork is more obvious. This calculation method of calculating the wind load, improve the anti-wind design method of the climbing formwork.

The quality of high speed machining is directly related to dynamic characteristics of spindle-toolholder interface. The paper established normal and tangential interactions of BT spindle-toolholder interface based on finite element contact theory, and analysed free modal in Abaqus/Standard. Then the result was compared with the experimental modal analysis. It shows that the finite element model is effective and could be applied in the future dynamic study of high-speed spindle system.

The finite element model of the stirring kneader shaft was built by PRO/E software, which was inserted into ANSYS. Next, the instantaneous dynamic analysis of the new stirring kneader shaft was carried out. The instantaneous dynamic response of stirring shaft about the exciting force of fluid was obtained, which was to optimize the structural parameters of the stirring shaft. The foundation for the next fatigue analysis was laid based on the instantaneous dynamic response; the fatigue life of stirring kneader shaft can be predicted.

Fatigue rupture is the major reason of crankshaft parts failure. Traditional fatigue analysis is fairly complicated and causes a great error. The finite element model of s195 engine crankshaft is created under SolidWorks environment, whose static analysis and fatigue analysis is carried out by using Simulation module. Also the vibration character of the crankshaft is calculated through modal analysis. Result shows the fatigue strength of the crankshaft is enough and it will not produce resonance in operation.

The finite element model of flexible clamp multi-point stretch forming (FCMPSF) was set up, and extensive contradistinctive analysis of forming limit and forming accuracy between FCMPSF and RCMPSF were done. The results show that under the same forming conditions, spherical part formed by FCMPSF is not easy to fracturing, dimpling and springback, and is easy to fit the die. The reason for this was analysed. The non-fracturing limited graph, the non-dimpling limited diagram and the average springback value of spherical parts formed by FCMPSF and RCMPSF were obtained. Finally, the forming experiment and error analysis of spherical part formed by FCMPSF were done, the results indicate that 3D parts with large transversal curvature can be shaped by FCMPSF and the forming quality was guaranteed.

The finite element model of a separately built one-storey underground frame was set up with software ANSYS/LS-DYNA and numerical simulation was done to study on surface overpressure and deformation of the underground frame beam under internal blast loads. It is found that the overpressure peak values on the beam end and middle surface are both much higher when the explosive is below the middle of beam and the peak on the middle surface goes up with the increment of explosive height while that on the beam end surface is not sensitive to the height. The numerical result also indicates that the soil around the frame nearly has no effect on surface overpressure of the frame beam. However, whether there is soil or not the beam deformation has much difference and the increment of the deformation is closely all the same for different soil thicknesses but under the circumstance of thicker soil the beam obtains less deformation upward in a short time after explosion.
