Modeling method of machine joints´ tangential contact damping based on BP neural network

To realize the unified modeling of machine joints´ tangential contact damping under multijoint conditions, the description method of the basic influencing factors´ characteristics of machine joints´ tangential contact damping is discussed. Then, the concepts of dynamic-intelligent neuron, generalized-intelligent BP network and generalized intelligent BP algorithm are proposed. On this basis, the unified modeling method of machine joints´ tangential contact damping under multijoint conditions is put forward based on artificial neural network technology. This is proved feasible by the given modeling example. This modeling method has the characteristics of both a traditional modeling method and the building of a database
