Research Of Heavy-truck Exterior Design

The heavy-truck is the indispensable means of production of economic construction, It can make Allocation of resources and Circulation of goods be fast high-efficient, and To the development of society have an effective material protection. With the development of the economic globalization, no matter in developed country, or developing countries, the heavy-truck has been an important means of transport. The R&D of heavy trucks has been developed gradually from safety, practicality in the early days to good mechanical performance, safety and environmental protection, comfortableness, large tonnage, upmarket. Good performance, comfortable driving, artistic styling, which are the new requirements to the R&D of modern heavy trucks.In initial stage of the 19th century, the R&D of heavy trucks already presented, and has a history of one hundred years until today. In Europe and North America, the heavy-truck product is in a leading position in technology and quality, and it has its own characteristics of the product and brand culture, which has become the target of the study and communication to other regions. China is now in a stage of rapid economic development, the construction of facilities, the development of the western region, the development of the old industrial bases in northeastern China, the development of the new socialistic country, the advocacy to the development of high-speed heavy-duty trucks, and so on. These state policies have already caused the market of truck to expand constantly, characteristics of large tonnage and upmarket have appeared in the market competition. In addition, many foreign brands entering the Chinese market through joint ventures and technology transfer make the R&D of heavy-truck develop towards internationalized level, and transform from "manufacturing" to "brand" "style".This subject is exactly based on the international perspective, regards model of the domestic and international heavy-truck products as the research object. we can find generality and difference of the model, then obtain law and method of the model, according to aerodynamics, art design, brand, chromatics and excellent heavy truck products at home and abroad, through searching, analyzing and summing up the heavy truck styling of different famous brands.The paper divides into seven chapters. The first chapter is an overview, it outlines the definition of truck, classification, and the content of modeling, namely, "what we design"; the second chapter describes and analyzes the status at home and abroad for heavy trucks, and get heavy trucks modeling features. Chapter III and IV describes about the heavy-truck modeling factors, " Which aspects do we begin from to design"; Chapter V Propose design methods, "How to design"; Chapter VI is the successful case analysis, which Verifies the applicability of the method, and it provides a set of design methods for the design; Seventh chapter is the conclusion.
