Hydraulic Modular Assembled Trailer Performance Study And The Digital Platform Development

The thesis firstly introduces the subject background of Hydraulic Modular Assembled Trailer performance study and the digital platform development. Then considering assembled trailer development trend at home and abroad and the actual demand of project entrusted enterprise, the thesis expounds the necessity and urgency of research subjects, the research purpose and significance. Meanwhile, on the basis of detailed analysis of hydraulic modular assembled trailer performance study in domestic and foreign, the thesis presents the main content of research subject.Secondly, the thesis analyzes the overall structure, the main technical characteristics and the splicing forms of Hydraulic Modular Assembled Trailer. And it also analyzes the influence these characteristics brought to assembled trailer performance. Then the thesis deduces the theory calculation formula of the max climbing capacity, the longitudinal passing capacity, the turning performance, the sideway stability, dynamic performance, brake performance of two tandem modular assembled trailer and two tandem bed assembled trailer. It also analyzes the influence that head wind load and sideway wind load brought to the sideway stability of assembled trailer. And it deduces theory calculation formula, which provides the theory basis for realization of the digital platform.After that, the thesis studies structural flexibility of 2 columns 6 axis,12 axis and 18 axis. It calculates their deformation value of structure in the rated load and analyzes the influence this structure deformation brought to the minimum longitudinal passing radius when the trailer passes the concave-convex road and the maximal ramp angle when it climbs the ramp.Afterwards, according to the modern software engineering theory and specific needs of enterprise, it defines the design requirement, function requirement and others of digital platform. It also designs function series flow graph and make it more detailed. Then the thesis makes a study of the digital platform outline design process, confirms the development way of the digital platform and software and designs the digital platform overall structure and operation process.Finally, the thesis makes a detailed study of realization of the digital platform. It designs platform startup covers, menus, dialog boxes, function modules and important programming statement. With this design, it calculates the combinations trailer properties. Then it tests the platform reliability with calculating data and the test result is satisfied.All of the studies offer a reference to the research of Hydraulic Modular Assembled Trailer performance of assembled trailer, solves the enterprise's practical problems, provide the digital platform for designing new products as well as new idea and possible ways for Hydraulic Modular Assembled Trailer performance research of assembled trailer, and have a fine practical significance.
