Fluid Solid Interaction

In order to solve the problem of choosing vibration mode of the cylinder shell resonating density meter, this paper analysis the dynamics of the resonator by ANSYS. The modal analysis result shows that the transverse n=2 and n=3 all meet the requirement, the fluid-structure interaction result shows that the transverse n=2 is more sensitive to the changing of fuel density than n=3. Final analysis of the influence by temperature and pressure on the vibration frequency shows that the influence by pressure is very little which can be omitted, but the influence by temperature is remarkable and needs to be compensated. The conclusions and methods of finite element analysis can be used for resonant liquid density meter design.

In order to get the deployable antenna with light weight but large size and high stiffness, this study investigated SMPC self-deployable driver mechanism based on the deformation mechanism of SMPC, and designed the SMPC space deployable antenna. The laminated shell structure with two pieces of back-to-back configuration was analyzed. Finite element analysis revealed that the reasonable central angle of the laminated shell cross-section was 90°. The ends fixing structure of the SMPC hinge was given. The function and structure of the hoop truss deployable antenna were designed to meet the functional and accuracy requirements.
