Optimization Design of Mortar Mixer Stirring Shaft

基于对砂浆搅拌机的搅拌轴的工作方式和性能的研究,详细介绍了搅拌轴的基本的工作原理和结构。通过ANSYS三维建模,并且对刀具进行有限元分析即进行相应的静强度、模态分析和疲劳分析,同时采用目标驱动优化的方法对搅拌轴进行优化,通过优化表明:优化后的搅拌轴的最大等效应力为544.14 MPa,并且质量较少。优化后搅拌轴的尺寸更加合理,从而为搅拌轴的结构设计提供合理的科学的参考依据。

Based on the research on the working mode and performance of the mixing shaft of the mortar mixer,it introduces the basic working principle and structure of the mixing shaft in detail. By means of ANSYS 3D modeling, it carries on finite element analysis to tool,namely static strength,the modal analysis and the fatigue analysis, and uses the method of goal driven optimization to optimize the mixing shaft. The optimization proves that the optimized maximum equivalent stress of the mixing shaft is 544.14 MPa,and the quality is less.The optimized mixing shaft size is more reasonable, thus providing reasonable and scientific reference frame to the structure design of mixing shaft.
