The U-shaped pipe located in the compressor piping system of the lyophilizer is studied in this paper. Its finite element modal analysis is carried out through the software ABAQUS, and at the same time, the experimental modal analysis is conducted by the software LMS Test.lab and its corollary equipment. Through the comparison between the finite element modal analysis results and the experimental modal results, it can be seen that the two results have good consistence, which verifies that the finite element model is reasonable. This paper provides reference for the further studies of the curving pipe vibration.

Intense Vibration

Aiming at the problem of intense vibration of the long pipeline delivering coal slime in the power plant, the finite element model of pipeline is established and modal analysis is carried out by ANSYS. The natural frequency and vibration characteristics of axial vibration are obtained. The vibration characteristics are studied and different pipe segments that produce bigger vibration very easily in operation are determined. Theoretical guidance about pipeline vibration under the external load for further analysis is provided.

The Finite Element Model

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 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

With the spindle system of a vertical gantry machining center as the research object, based on the vibration theory and finite element method, the modal analysis of spindle system is studied. Firstly, the finite element models of the mandrel box body and motorized spindle frame of spindle system are established by ANSYS. And then do the modal analysis of singleton in the boundary of free constraint. Lastly, based on the analysis results to establish the finite element model of the whole spindle system and do the modal analysis of the whole system which under constraint condition. The result shows that the swing of motorized spindle frame and motorized spindle sleeve of spindle system are more obvious.

The 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.
