Effective Computer-Aided Engineering in the Automotive Product Development Stages

2001-03-05
2001-01-0764
This paper show how the automotive product development process is presented in four distinct stages. The specific type of task, to be presented at each stage, is discussed. Specific CAE (Computer-Aided-Engineering) tasks, such as FEA (Finite Element Analysis), to be used at each stage are discussed. Detailed steps to follow are presented, as well as a check list of tasks are included. The changes and increased effectiveness (developed over 15 years of utilization) are discussed.

A modeling methodology is being developed to aid in routing and predicting movement of brake hoses with the objective of having an adequate representation in a Computer Aided Design (CAD) system for virtual prototyping. Once mount points and orientations have been specified,material properties and length determine the path of the hose. Data, collected on a straight and deflected hose at several points along the length of the hose, were compared to an ADAMS simulation. Problems that were encountered in metrology and data transfer are discussed along with their potential impact on the modeling accuracy.

For the 2003 model year DaimlerChrysler Corporation will launch a totally new 5.7L V-8 engine for applications of the Dodge Ram pick-up truck. The new engine was created largely within a digital environment using the latest computer aided design (CAD) and computer aided engineering (CAE) techniques and tools. Utilizing a co-located team of design engineers, designers, and CAE engineers enabled the simulations to impact the design from program inception to the assembly line, saving program time and investment. This paper describes the successful merging of design and advanced analysis techniques by highlighting examples throughout the new HEMI® program. Case studies include issues in the areas of structural optimization, engine loading, lubrication circuit, cooling circuit, and manufacturing.
