摘　　要：本文以SHJ-600高扭矩同向双螺杆挤出机传动箱箱体为研究对象,通过对传动箱的工况进行受力分析,计算分析箱体的受力载荷;通过对传动箱箱体的三维建模,采用有限元模拟的方法对箱体进行线性静力分析和模态分析,得到该箱体的变形和等效应力应变云图,找出应力集中区域,同时对比箱体前六阶固有频率和振型特征,找出激励频率与固有频率之间的关系,进而验证了箱体结构的合理性,为后续箱体的结构优化提供思路。This article takes the transmission box body of the SHJ-600 high torque co rotating twin-screw extruder as the research object.By analyzing the working conditions of the transmission box,the force load of the box body is accurately calculated.At the same time,3D modeling technology is used to model the transmission box body,and finite element simulation method is used for linear static analysis and modal analysis.By analyzing,the deformation situation of the box and the equivalent stress-strain distribution cloud map are obtained,and the stress concentration area is identified.In addition,by comparing the natural frequencies and mode characteristics of the first six orders of the box,analyzing the relationship between excitation frequency and natural frequency,the rationality of the box structure can be verified,providing the oretical basis and direction for subsequent structural optimization.
