Research on damping parameter identification of elastomer buffer

摘要：

　　The object of this paper is the changing process of damping force as the falling weight impacting the elastomer buffer.The whole mechanical system is built up through practical test and simulation.According to the type of elastomer buffer and the experimental process in shock environment, velocity damping force identification model was established.Wavelet denoising and least square method were used for parameter identification of damping force.Considering the data saturation problem in the traditional least square method, the limited memory least square method was obtained to improve the identification method.The results of parameter identification of damping force based on limited memory method proved that the limited memory method was superior to least square method.The numerical results demonstrate the effectiveness of the identification model.
