Knowledge-based Engineering And Heavy Commercial Vehicle Air Suspension System Design And Research

Increasing the quality of life of people, cars are increasingly in human life play an important role. For car comfort and convenience of operating performance, but also become one of major concern. For the heavy commercial vehicles, vehicle suspension is top priority. This article is in the study of domestic and foreign automotive suspension to analyze the situation, according to the theoretical knowledge of suspension design, a section of the suspension system for heavy commercial vehicle design and development and research.Heavy commercial vehicles is an important pillar of the logistics industry, China's auto industry is an important concern, one of the world while also occupies an important position. The load of heavy commercial vehicles, transport efficiency and customer comfort is the focus, in order to better improve comfort, optimize the vehicle's ride, to better improve the efficiency of the transport of heavy commercial vehicles, we need to reduce the car's major assembly weight, the lightweight design, you also need to increase the volume of container, and then depending on the specific use of models to match the height adjustment feature different sites. For existing materials, technology did not significantly increase under the premise of the assembly only by reducing the amount of carrying capacity and use more of the assembly, so automotive engineers develop and design space of thinking is very limited. Thus, with the development of heavy vehicle, its chassis, load capacity and height adjustment, height memory function of the rising demand, the major automobile manufacturing plant sites are introduced in the high-end commercial vehicle air suspension system used on the match.In the first part of this first study is to analyze the significance of the automobile suspension from the vehicle ride comfort and the requirements of the significance of vehicle suspension design analysis; then analyzes the characteristics of heavy commercial vehicle suspension structure and the current domestic and international trends; and research on this paper, the air suspension of the structure, characteristics, development processes and trends are analyzed; final content of this study brief.The second part is to study the theory of automotive suspension design, ideas and methods. First, the basic concept of the suspension system, the system constitutes the full understanding of the basic composition of vehicle suspension; followed by analysis in the previous work through the process of continuous learning, research, and the formation of the suspension design to improve the basic idea, summary suspension the main requirements of system design and an important concern; then the basic concepts of air suspension, composition, layout methods, control systems and design analysis and research; last is a summary of automobile suspension design and induction. The third part is mainly based on knowledge engineering vehicle suspension system design. The first is the basic process of automotive suspension design analysis; followed the basic design concept is based on work experience summed up in this study the development of heavy commercial vehicle suspension design process; then the concept of knowledge-based engineering parameters of the suspension system design module development; fourth point is based on TOP-DOWN design of the suspension system developed for the modules of the application analysis; Finally, knowledge-based engineering design of automotive suspension systems research and summary. The fourth part is the section of a heavy-duty commercial vehicle electronic control air suspension, the entire design process, methodology, calculation and design process analysis and research. Part V is the air suspension, which models the real vehicle validation and verification analysis. The last part is a summary of this article, including research methods, design ideas and research findings, as well as from the experience gained and lessons learned.In short, this knowledge-based engineering design of automotive suspension systems and research to achieve a certain depth, the product development design, can play an important role. This development process conducted by the suspension of research, has been applied to heavy-duty commercial vehicle development process, there are some practical value. As the performance of vehicle suspension design and smooth performance related to comfort, road conditions is complex, it also has some limitations. This article is based on knowledge engineering preliminary design of suspension systems theory, a thorough analysis is not enough, take some time and accumulated experience, achieve better verification results.
