Passenger Vehicle Door Trim Panel Development Based On Modern Design Method

In this paper, through the analysis of the development trend of thepassenger vehicle door trim panel, the design process of door trimpanel, analyzes and expounds several aspects of the arrangement of conceptdevelopment and engineering development, to illustrate the modern designmethod and process use for door trim panel. Research content for the door trim panel development product scheme, overall arrangement, the keyperformance parameters, structure design, finite element analysis,several aspects of trial test, optimization improve ect. The door trimpanel fully meet the technical, manufacturing and assembly need; meet thedemands of the ergonomics, and convenient repair. The door trim paneladopts modular design an improve the convenience of assembly, operation,but also improves the production efficiency. At the same time the doortrim panel assembly with stiffness, strength enough to ensure the smoothsurface, uniform gap good decorative effect. And has the characteristicsof light weight, low cost. Development and design of door trim panel notonly to meet the general series models, save the die cost, shorten thedevelopment cycle, early occupation of the market, but also to make theproduct has very strong market competition ability. Therefore, thedevelopment and research of door trim panel on the basis of modern designmethod has the extremely vital significance.This paper is modern design method summary and investigate of theevery stages for the door trim panel development. From concept developmentstage, to engineering development stage to make full use of advancedmodern design means, formed a set of design process and method based onmodern design method. The research indicate, the modern design method isbetter than the tradition design method on guarantee product performance,shorten the development cycle, save the cost. to increase the company hasvery strong market competition ability. The research of the modern design method, for after passenger vehicle door trim panel design and developmenthas accumulated valuable experience.
