| Abstract: | The damping at joint surfaces plays an important part in a machine structure. It is influenced by many factors, for example, the pressure at joint interfaces, joint materials, the machining method and the roughness, as well as vibrating frequency. The relationship between them is nonlinear and complicated. The characteristics of above influencing factors were described and the neural network modelling method for the basic data of the tangential contact damping of joint surfaces acquired in experiments was presented in this paper. The obtained model by this method can be effectively and conveniently used in the design of a machine structure. This method has been proved feasible by a modelling example, and the modelling has a high efficiency and precision. |
