Comparison Results

In this paper, the two methods for solving finite element problem, theoretical calculation method and ANSYS simulation analysis method, were used to study deformation and stress situation of each node of triangular truss under different distribution loads. The results of theoretical calculation were compared with those of ANSYS simulation, which showed that the counter-acting forces of each node were exactly the same. For the calculation results of the equivalent stiffness constants of each unit could not be accurate, values of each node deformation calculated by theoretical calculation could be error, but the maximum error rate was no more than 3.6%. By the comparison results, conclusion could be made that the results of ANSYS simulation are more intuitive and image, the values are more accurate and reliable, comparing with those of theoretical calculation, the influence of accuracy of equivalent stiffness constant is much more smaller.

In order to improve the detect performance of the traditional pipeline magnetic flux leakage(MFL) in-line inspection tools, the method of tri-axial pipeline MFL in-line inspection is advanced. By the three leakage magnetic field components: axial, radial and circumferential, the pipeline defects are recognized. Applying finite element method to build the simulation model of pipeline MFL in-line inspection, then proceeding 3-D simulation analysis. The three components of leakage magnetic field (axial, radial and circumferential) can be obtained by using ANSYS 3-D simulation, and the pipeline defects’ existence as well as the change of the defect’s size can be estimated by the three components’ graph. The simulation results indicate: By the ANSYS 3-D simulation, it proves that the tri-axial pipeline MFL in-line inspection can be achieved and the inspection can be used to improve the level of traditional pipeline MFL in-line inspection.

Autofrettage Pressure

This paper takes the ultra-high pressure (103.5MPa) valve body as the research object and adopts the finite element method to perform simulation analysis on the three bearing conditions involved with the valve body, i.e., autofrettage pressure, discharge and working pressure. The simulation shows identical results with the theoretical calculation. The relationship between the maximum equivalent stress and autofrettage pressure during the operation of the valve is obtained from the simulation results; therefore the best autofrettage pressure is determined. When determining the maximum value of autofrettage pressure, the maximum pressure, at which reverse yield does not happen, and the complete yield pressure shall be taken into consideration, with the smaller value of the two taken after comparison and analysis. When the size of the valve body is fixed at certain value, the best autofrettage pressure is not a fixed value, but it varies with the change of working pressure.

Length To Diameter Ratio

The dynamic simulation analysis method is adopted to investigate the dynamic damping characteristics of lathe tool with large length to diameter (L/D) ratio. The multi flexible body dynamical simulation model of dynamical damping lathe tool with large length to diameter ratio is built up according to the actual experiment lathe by using the software ADAMS and ANSYS. Simulation analysis of the multi flexible body dynamical model which has been optimized shows that the system damping performance is improved greatly. On this basis the relationship of rubber bush, mass body and vibration absorption cavity is discussed. And the result of the discussion indicates that the shape of rubber bush should be confirmed by repeatedly simulating the model.
