摘要
以圆管带式输送机机架整体结构为研究对象,建立了整体结构的有限元力学模型,并进行了模态分析,得到结构前6阶固有频率及振型图。计算表明,对于这种长距离多弹性支撑整体钢架结构,其刚度及质量分布与各部件的连接处理是否合理,对整体结构自身动态性能影响较大。
In the paper we research the whole frame of the pipe conveyor and establish the finite element mechanical model for the whole structure.Furthermore the modeling analysis is made.The preceding 6 steps natural frequency and mode shape of the structure are obtained.The calculations indicate whether the distribution of stiffness,the distribution of mass and the joint of every components are reasonable for the whole frame structure with long distance and multiple elastic bracings will affect ralatively on the dynamic performance of the whole structure.
