Abstract

A structural and material analysis of individual elements of the mixing-unloading spiral and shell segments of the innovative mixer drum of the hydraulic truck concrete mixer with a capacity of 12 m3 was developed. A complex CAD design process of individual elements in terms of the developed manufacturing technology was carried out. The construction of the mixer components was verified in the 3D-CAD system and a numerical analysis of stress distribution using the finite element method (FEM) was carried out for key segments of the spiral, which directly determines the implementation of the correct and efficient concrete mixing process. The research resulted in the development of comprehensive technical documentation of the original mixer structure, including executive drawings of the components along with a description of the manufacturing technology and the choice of the initial material–steel with increased abrasion resistance. The results of the completed research process were used in the next stage of research, i.e. bench tests of the innovative design of the 12 m3 mixer drum.

容量为12 m³的新型混合滚筒的结构和材料分析

对容量为12 m3的新型液压混凝土搅拌车搅拌鼓的搅拌卸载螺旋段和壳段的单个元件进行了结构和材料分析。根据已开发的制造技术，对单个元件进行了复杂的CAD设计。在3D-CAD系统中验证了搅拌机部件的结构，并对螺旋关键段的应力分布进行了有限元数值分析，直接决定了正确、高效的混凝土搅拌过程的实施。研究的结果是开发了原始混合器结构的综合技术文件，包括部件的执行图纸以及制造技术的描述和初始材料的选择-具有增强耐磨性的钢。完成研究过程的结果将用于下一阶段的研究，即12 m3混合机转鼓创新设计的台架试验。

期刊介绍： In technical mechanics , peer-reviewed papers from all fields of mechanics are published. A major concern is the rapid availability of research results for industry and science. In this sense, especially those contributions are preferred, which include not only new results and findings but also their practical application. The journal Engineering Mechanics publishes refereed original articles on Engineering Mechanics in its broadest sense. It is intended to provide a forum for a rapid transfer of research results to industry and science. In that sense contributions are encouraged the practical application of new results and scientific findings.
