In order to optimize the kinetic parameters of arrow shaped shovel, the paper carried on the modal analysis and the 3D graph was drawing by the application of Pro/E software. The finite element model was established by using ANSYS Workbench. After the constraint processing, the first six model shapes of the rack were obtained through the modal analysis of arrow shaped shovel. Based on the modal analysis, it can be found that the first six natural frequencies enlarge with the increase of the order, and the odd order of principal modes are horizontal hunting along shovel handle on both sides, the even orders are up and down perpendicular to horizontal direction. The maximum deformation of the first six model of the rack occurs at shovel head. The results present a theoretical reference for improving and optimizing the shovel.

Crankshaft is one of the important parts of reciprocating compressor. It takes a large reciprocating compressor crankshaft as the research object. First it establishes the three-dimensional solid model of the crankshaft by the software Pro/E. Then it contacts the Pro/E and ANSYS Workbench by the interface to establish the finite element model of the crankshaft. After taking the modal analysis and calculations of the crankshaft in the ANSYS Workbench module, it obtains the foundation for the design of the crankshaft structure.

In order to attenuate the deformation of spray boom, a finite element model built based on ANSYS, according to the reasults of numerical modal analysis and modal texting, the reliability of the finite element model was affirmed. Then, an isolator was introduced between spray boom and frame, a frame-isolator-spray boom model was built in ADAMS. The effect of the isolators which have different parameters was research, the reasult shows: The isolator has much effect on attenuating spray booms deformation, the stiffness of isolators spring dampers has little effect on spray booms deformation, but the damping of isolators spring dampers has effect on spray booms deformation.

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.

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.
