摘　　要：运用有限元软件ANSYS建立了YHZS50型混凝土搅拌站钢架结构有限元模型,对该钢架结构边界条件进行了简化,应用ANSYS有限元分析软件对主钢架进行了模态分析,计算了主钢架自由状态下的固有频率及振型特性对搅拌站整体性能的影响。在ANSYS中用耦合来模拟主钢架纵、横梁以及连接板之间的铆接,单元类型采用的是梁BEAM188。主钢架有限元模型正确性通过实验得到了验证。Established YHZS50 type concrete mixing station finite element model of the steel-framed structures by ANSYS, boundary conditions of the steel frame structure was simplified. The main steel modal analysis of mobile concrete mixing plant was carried on ANAYS. The natural frequency was calculated and the influence of modal characteristics to the overall performance of the mixing station was analyzed. Using coupling of the ANSYS simulated the riveting of stringer and crossbeam of main steel frame. And unit type was used BEAM44, BEAM188
