Abstract

In this paper, firstly the influencing factors of contact stiffness of machine joint interfaces and their description method are introduced and discussed. Then a weight smoothing BP algorithm is introduced briefly. It has better generalization performance. Basing on this algorithm, the intelligent modeling method of contact stiffness of machine joint interfaces under multijoint conditions is proposed for the first time. This method is proved feasible by the given modeling example.

机械关节界面接触刚度的智能建模
本文首先介绍和讨论了机械连接界面接触刚度的影响因素及其描述方法。然后简要介绍了一种加权平滑BP算法。具有较好的泛化性能。在此基础上,首次提出了多关节条件下机械关节界面接触刚度的智能建模方法。通过实例验证了该方法的可行性。
