摘　　要：利用有限元软件ANSYS建立了某型号颚式破碎机动颚的参数化模型,将有关结构参数变量指定为优化设计变量,以结构在已知工况下的应力为状态变量,在此基础上采用有限元数值方法,对动颚进行优化设计以减少其重量;同时对优化前后的模型进行了模态分析,以检验优化对结构动特性的影响,从而为实际生产设计部门进行优化结构、节省材料用量提供理论依据。Using the engineering analysis software ANSYS, a parameter structure model for the mobile jaw body of some type of single toggle jaw crusher was built. Some relevant structure parameters that affect mobile jaw deformation and mass were converted to be optimal design variables. The stress and the displacement of the mobile jaw under known work conditions were assigned to be static variables. Subsequently, optimal design for jaw was also finished, and weight of jaw structure is decreased with the finite element numerical method. Finally modal analysis for jaw model before and after optimal analysis was fulfilled and optimal result is verified. The results can be used to provide a theoretical foundation for executive departments to design an optimal valve structure and make a cost - effective use of materials.
