基于人工神经网络的摊铺机rn振动梁结构动态设计研究

摘要

基于动力学逆问题的基本原理,讨论了摊铺机振动梁结构动态设计中的主要问题.文中先分析了振动梁的动力学特性对各种设计参数的灵敏度,从而得到了主要设计参数,在此基础上提出了一种基于人工神经网络技术的结构动态特性优化方法.数值计算表明了该方法的有效性.%Based on the principle of the dynamic inverse problem,this paper discusses the method of structural dynamic design of a road paver's vibrating bar.At first,the paper analyzes the sensitivities of natural frequencies of the bar to its designing parameters and the key ones are found.Secondly,an artificial neural network is adopted to optimize the dynamics of the vibrating bar.A numerical example showing the effectiveness of the new method is provided.
