Steady State Temperature Distribution Study of Laminated Damping Apparatus with Nonuniform Heat Generation

摘要

To figure out the temperature distribution laws of laminated damping apparatus, a method based on heat flow distribution and superposition methods is proposed to solve the steady state temperature distribution of the laminated damping apparatus with nonuniform generation. Heat flow and temperature distribution formulas of the apparatus are derived. A numerical example is performed to verify the correction of the proposed method. The temperature results obtained by the method are compared with those obtained by FEM in the example. The results show well consistency of each other and the temperature absolute errors of each layer are very small, which indicates that the method is valid. The obtained heat flow and temperature distribution formulas can provide reference for the development of variable parameter laminated damping apparatus.
