摘要
混凝土搅拌车叶片是实现搅拌筒功能的主体结构,具有搅拌和出料功能。在分析搅拌叶片总体结构的基础上,介绍了前锥、圆柱段、后锥各部螺旋叶片的设计特点及设计方法,提出了新的改进措施,并运用Pro/E软件建立螺旋叶片三维模型,进行有限元分析。改善了叶片结构性能,提高了使用寿命和工作效率,为搅拌叶片的结构改进设计提供了参考依据。
Mixing blade with the function of mixing and discharge is the main component of a concrete mixing truck.In traditional method,the front cone and the back cone adopt equiangular spiral,the middle is Archimedes spiral.Based on analysis of design method and structure characteristics of helical blade,this paper puts forward a new method,in which non-equiangular blades are adopted in front cone and back cone,then it establishes three-dimensional model of mixed blade with Pro/E and finite element analysis software.The design method can provide reference for structural improvement and design of mixing blade.
