[Abstract]:With the development of modernization, environmental protection has become an important issue of the times, and has attracted extensive attention in various countries of the world. It is in this way to reduce production pollution. Under the requirement of promoting environmental protection and pollution-free transportation of bulk materials, the tubular belt conveyor emerges as the times require. At present, the tubular belt conveyor is the most advanced material conveying equipment in the world. Mechanical structure analysis, parameter analysis, finite element analysis and computer simulation technology are used to analyze and study the pipe belt machine, and digesting and absorbing foreign advanced technology and equipment. The transformation provides the theoretical basis and has the important guiding significance to the actual production. The main task of this subject is to introduce the working principle and characteristics of the tubular belt conveyor and determine some parameters. Then the finite element analysis method and the post-processing module are introduced in detail. Aiming at the typical mechanism such as the transmission roller and its bearing seat, this paper introduces in detail the process of establishing the finite element model in the ANSYS software, simulates the force situation under the actual working condition, and carries on the strength check. The reliability of the improved structure is analyzed. The finite element analysis results of the transmission drum and its bearing seat of the tubular belt conveyor show that the strength of the existing transmission roller mechanism and bearing seat is still reliable and meets the design requirements. It provides the guidance for the further optimization design of the pipe belt machine. Based on the finite element analysis, the mechanical model and mathematical model are established, and the mechanical structure, force and energy parameters and their simulation of the main parts of the pipe belt machine are analyzed in detail. The paper analyzes and solves the difficulty of strength analysis of the transmission drum and its bearing seat in the tube-strip machine, and the theoretical knowledge and modern design method used in solving the problems in the tube-strip machine are very advanced and advanced. The results obtained are all accurate and accord with the design requirements. Therefore, this paper provides a great convenience and reference value for the users to study the pipe and belt machine in the research and discussion of this subject.
