| 摘 要： | 在连续挤压机机架的设计中,以往采用类比的经验设计方法,缺乏对机械结构强度的精确验算,造成所设计的机械结构尺寸与重量偏大。利用有限元分析软件ANSYS对TLJ400型连续挤压机机架建立三维实体模型,并进行结构分析,得到了精确的强度值和机架的应力分布情况;在对机架进行强度校核后,提出了一种结构改进的方案,并通过有限元仿真分析验证了其可行性。结果表明,采用该方案进行的结构改进能够减少材料的使用,实现机架的轻量化。

| Abstract: | Experiential analogy design method was used in the designs of the frame of continuous extrusion machine in the past.It was devoid of precision checking calculation for mechanical structure strength.As a result,the size and weight of the mechanical structure,which was designed,were higher.Finite element analysis software ANSYS is applied to build a 3D model of the frame of the TLJ400 continuous extrusion machine.Structure analysis is carried out under a certain working condition,and precision strength value ... |
