| In order to study the equivalent Young's modulus of Hastelloy material with honeycomb structure suitable for the dynamic
analysis of the seal ring assembly, a modal testing device for the seal ring assembly was built and the finite element model of the seal ring
assembly was established. Based on modal analysis and bisection approximation theory, taking the natural frequency derived from the
modal testing as the reference value, numerical modal analyses of Young's modulus of Hastelloy material were consecutively carried out
using the bisection method to approximate the reference natural frequency, and obtain equivalent Young's modulus of the Hastelloy mate?
rial with honeycomb structure. The results show that when the equivalent Young's modulus of Hastelloy material with honeycomb structure
is 0.304GPa, the maximum relative error between the natural frequencies from numerical modal analyses and test results is less than 1.3%,
which can be used to analyze the dynamic characteristics of the seal ring assembly. The equivalent Young's modulus with 0.304GPa is veri?
fied by seal ring assemblies with different structural parameters, and the maximum relative error is less than 3%, indicating that the
equivalent Young's modulus of 0.304GPa for Hastelloy material with honeycomb structures has high accuracy and universality in analyzing
the dynamic characteristics of seal ring assemblies. |
