振动响应为实现水电站厂房结构振动的整体运行状态智能预测,解决多振源耦合与振动响应随机性等问题,以某一河床式水电站厂房振动响应为例,提出了一种基于IGA-BPNN的水电站厂房振动响应预测模型.首先利用IGA对BPNN初始权重值和阈值进行优化,充分发挥IGA高效并行,全局搜索的特点,再通过BPNN网络训练得到结构振动位移预测值.原型...
Considering the issues that the relationship between the compost maturity degree and evaluation parameters is a nonlinear and uncertainty, a compost maturity degree evaluation method based on improved genetic algorithm (IGA) and radial basis probabilistic neural network (RBPNN) is presented. The fitness...
