Study on the Numerical Simulation of Strength and Axial Stiffness for Reinforced S-Shaped Titanium Alloy Bellows Components Based on Finite Element Method
摘要
In order to research stress distribution, displacement distribution, and axial stiffness of titanium alloy reinforced S-shaped bellows with different structural parameters, the finite element analysis software ADINA was used to simulate the reinforced S-shaped bellows components under actual operating conditions. The simulation analysis results can be obtained from post-processing module, and the maximum Von-Mises stress of the S-shaped bellows component can be found near the peak position of internal surface. For a single waveform, the Von-Mises stress distribution shows a gradual decreasing characteristic from the peak to the adjacent troughs, and the stress distribution characteristics of each wave are basically the same. Axial stiffness of the reinforced S-shaped bellows components can be improved significantly by reducing the radius of internal and external contour lines. These results obtained based on finite element analysis have some theoretical guidance significance for the structural design and optimization of S-shaped bellows components.
