[Abstract]:With the acceleration of national urbanization, the commercial concrete market has been unprecedented development, the role of concrete mixing truck is particularly important. In this paper, according to the design requirements of a company, the characteristics of the existing concrete mixing truck are analyzed and summarized, and the analysis and design of its key parts are carried out by using 3D modeling technology and finite element analysis technology. The design and research of a new type of concrete mixing truck have been completed, and good economic and social benefits have been obtained. First of all, the existing problems of concrete mixing truck are analyzed and summarized, including short service life of tank, short service life of mixing blade, unsatisfactory mixing effect and discharge speed, high discharge residual rate, etc., and the causes of the problems are pointed out. And used in the design of the whole vehicle and parts. Then, the parametric model of mixing tank and stirring blade is established by using 3D modeling technology and SolidWorks software, and the finite element model is established by introducing IGES format into finite element analysis software ANSYS. The finite element analysis of mixing tank and stirring blade is completed. Based on the results of finite element analysis, the mixing tank and stirring blade are improved. Finally, the main components, such as auxiliary frame, control mechanism, tank rear support, water supply system, loading and unloading device, are analyzed and improved, and the corresponding design scheme is put forward. The design and research in this paper prolong the service life of the tank and the mixing blade of the concrete mixing truck, increase the discharge speed, reduce the discharge residual rate and production cost, and achieve a better mixing effect.
