摘　　要：为避免SJ200型双湿式搅拌机设计时底部框架采用框形结构可能出现的弱刚度问题,对底部框架进行了动静态性能分析。首先选用Pro/E三维软件对该结构进行了三维建模,然后将所建三维实体模型导入ALGOR有限元分析软件,利用ALGOR有限元分析软件对底部框架进行静态和模态分析,得到了该底部框架的应力分布、应变分布和固有频率等动静态性能参数,其最大应力值未超过材料的许用应力,最大应变也满足设计要求,固有频率偏离该搅拌机的工作频率。从整个设计结果来看该底部框架的设计较为合理,可应用于实际生产。In order to reduce the weight of SJ200 Dual Wet Mixer, it establishes 3D model with Pro/E, transfers the model into ALGOR finite element model, analyzes the frame structure function of the bottom frame such as static and dynamic. The static and dynamic performanee results are the stress distribution, natural frequency and strain distribution. The maximum stress value is under the admissible stress of material, the maxi- mum strain is also satisfied the design requirements and the natural frequency is far always the mixer operating frequency. So the design is more reasonable and can be applied to actual production.
