| Abstract: | This paper is mainly to research the method of the structural stress recognition for tower crane jib based on BP neural network by taking a tower crane as the object of study.The BP neural network is set up and trained,then the reliable stress recognition network is obtained by training to the different work conditions.The relation between the tower crane characteristic parameter and the structural stress is built,and then the structure stress responses of the jib are recognized.The above results provides t... |
