通过实际观察双卧轴混凝土搅拌机机架沿轴向的晃动现象,结合双卧轴混凝土搅拌机实际工作特点,对发生这一现象的原因进行分析,并对机架结构进行简单改进,利用ProE三维建模软件及Ansys有限元分析软件对改进前后机架的轴向晃动过程进行三维实体建模及仿真,结果表明,搅拌机轴向的最晃动量、总晃动量、最大应力均有较大幅度的减小,该研究对实际工程应用具有一定的参考价值。 By observing the sloshing phenomenon of the double-shaft concrete mixer rack in the axial direction and analyzing the actual working characteristics of the double-shaft concrete mixer, the reasons for this phenomenon were analyzed and the frame structure was simply improved. The simulation software and Ansys finite element analysis software are used to simulate and simulate the axial sloshing process of the front and rear racks before and after the improvement. The results show that the maximum amount of rocking, the total amount of rocking and the maximum stress of the mixer are greatly reduced Small, the study of practical engineering has a certain reference value.
