The Computer Assistance Conceptual Design Of Bus Design Applied Research

Along with the globalization development, the product innovation gradually becomes the core factor of the enterprise competitive power, as the product innovation the core, the conceptual design is valued by people day by day, but along with the computer technology development, the computer assistance conceptual design also become the research the hot spot day by day.The computer assistance conceptual design to deepen the traditional concept of computer-aided design technology, will design the main core from the original detailed design stage to transfer the concept of the product design stage. This is because the concept design stage of product features, performance, reliability and customer satisfaction is very important impact. Therefore, in order to become a new generation of product designers must attach importance to product development on the initial phase of the conceptual design.In intense market competition situation, the new technical new method of the passenger train modelling designed obtain the further development, the computer assistance conceptual design of the passenger train modelling is a technology which has started in the 20th century, was inevitable result after that the computer assistance design obtains the widespread application, was improvement and the enhancement to the traditional passenger train modelling conceptual design.The computer assistance conceptual design could speed up the passenger train design and the performance history, the management is easier, and it reduces the time of product to research and develop, reducee the development cost.In the article elaborated the product conceptual design basic content, the product conceptual design flow as well as product conceptual design some methods, and proposed constructs the computer assistance conceptual design system by the product system design method the thought, namely designs three basic essential factors take the functional design shape design color as the primary coverage computer assistance conceptual design system (the CACD system).Here I take the enterprise K01 passenger train modelling design as an example, has analyzed the CACD system in passenger train modelling design application, and carries on by this foundation extends, unifies the CACD system to make the more thorough applied research to the passenger train modelling conceptual design.
