径向等厚振动给料机是为转底炉设计的可以实现径向等厚布料的装料设备。本文利用有限元分析软件ANSYS,对某型号振动给料机进行了模态分析和动应力分析,得到了该振动给料机的模态参数和动应力分布规律,针对料槽的应力薄弱环节,提出了具体的结构改进及优化方案,可以大幅度地降低给料机的动应力水平。 Radial equal-thickness vibrating feeder is designed for rotary hearth furnace can achieve radial equal-thickness fabric charging equipment. In this paper, finite element analysis software ANSYS was used to analyze the modal analysis and dynamic stress analysis of a certain type of vibrating feeder. The modal parameters and dynamic stress distribution of the vibrating feeder were obtained. According to the stress and weakness of the trough, Proposed specific structural improvements and optimization programs, can greatly reduce the feeder dynamic stress level.
