The transient thermal-structural analysis of The high-precision sound velocimeter

The high-precision sound velocimeter is the standard of other sound velocimeters. It needs to have a reliable mechanical structure. The structural stability is the core part of this machine, and only tiny deform can be permitted in its working condition with the specified temperature in sea water. To ensure its high-precision in its working and changing environment condition, author need to calculate its deformation by transient thermal-structural interaction analysis. Using interaction between thermal and structural by finite software ANSYS Workbench this paper finished the numerical calculation of its working in designed condition. The analysis result show that: The maximum displacement appears in the forked places of the sample´s structural stability which equipped with transducers, and the maximum stress appears in the same place by the surrounded sea water in the specified. The deforms and stress fit the design requirement, provide the basis for the design.
