连续挤压机底座轻量化研究

Research on lightweight base frame of continuous extrusion machinery

连续挤压机底座是连续挤压设备的核心构件,通过ANSYS优化技术进行连续挤压机底座轻量化设计和模拟。文中采用底座三维实体模型和结构强度分析并辅以试验测试,按照材料强度和底座刚度要求提出底座的改进方案,在此基础上应用零阶优化方法和ANSYS优化模块进行了结构优化。经全面分析轻量化之方案,证明其新结构可以改进设计、提高整机性能和强度、降低重量和成本,为今后同类设备的设计提供参考。

Base frame is the key loading structure of the continuous extrusion machine, the whole approach to optimize the base frame based on ANSYS optimize theory and software was introduced. The 3D model of base frame was constructed and the simulation stress results was analyzed. Additionally it was verified by tension measuring on the running machine; a modified design was introduced and then optimized by ANSYS optimal process. The optimal lightweight structure was fully evaluated and proved to be successful. This design will improve the machine performance and base frame strength, at the same time, reduce the weight and cost. New design guidance was also built on this research for further reference.
