Body in white forms a major structure in any automobile. It is responsible in providing structural rigidity to vehicle, safety, frame and a skeleton to support all body parts of vehicle. When it comes to judge the performance of vehicle, BIW is analyzed not only for its strength and shape but also weight. Light weight BIW structures have seen to be developed rapidly in order to fulfill requirement of best vehicle performance in dynamic conditions. Since then lot of efforts have been put into CAE, materials research, advanced manufacturing process and joining methods, each plays a critical role in BIW functionality. Constructional designing, development of light materials with improved strength and special manufacturing practices for BIW are few research areas with never ending questions. This paper attempts to review various factors studied for weight reduction and solutions provided so far. Some of the major findings are briefly discussed and suggestions are made for future research.

Abstract Body structure design needs to meet multi-attributes requirements such as global bend stiffness/modal, torsion stiffness/modal, Noise and velocity transfer functions (NTF/VTF), and others. Computer-aided engineering (CAE) is a significant way to enhance the accuracy of design results. However, it also brings computation burden for optimization. In order to improve the performance and reduce the weight of automobile body structure, this paper presents a novel process of body CAE multi-attributes optimization. Four significant phases are described: 1) Sensitivity analysis for each body CAE performance, 2) MDO process, 3) Non-sensitive gauges reducing, and 4) Slightly optimization. Considering the mixed variables in the MDO process including continuous geometry shapes and discrete gauges, the developed continuous relaxation method was employed to deal with such situation.

Abstract This paper introduces the experimental test results of an investigation to understand the relationship between the leading offset and squeal propensity. In addition Transient Analysis (TA) and Complex Eigenvalue Analysis (CEA) are used simultaneously as a means to compare the experimental approach to two different numerical tools, so evaluating the validity of each theoretical approach. To confirm the CAE results. An ODS was recorded of the brake using a 3D laser scanning vibrometer. Even though the CEA approach is very popular in the study of brake squeal noise, there are some limitations and difficulties in replicating the real phenomenon especially containing unstable behavior. The differences are due to weak pad contact stiffness and friction characteristics which are dependent on the relative interface velocity between pad and rotor. It is necessary to consider stick-slip vibration and time domain analysis in addition.

The increase in the number of silicon foundries and CAD/CAE system and workstation companies, and the problem of movement of data among in-house design systems has made a standard interchange format for electronic design data essential. The benefits of the general adoption of a standard interchange format are important and far reaching. The customer receives a much wider variety of feasible choices, and free competition in both CAEYCAD system/tool businesses and foundry businesses is enhanced. The electronic circuit designer and customer of CAE/CAD system and foundry service can expect compatibility among these products. The designer can choose equipment and services best suited for a particular task with a minimum of overhead. Foundries can work with customers regardless of the CAE/CAD equipment that the customer is using.

This report documents the findings of an industry study panel convened by the Electronic Industries Association(EIA) under the auspices of the Computer-aided Acquisition and Logistics Support (CALS) Industry Steering Committee to determine the best utilization of product data description standards for electronic configuration items in the near term. Appendix A contains a brief outline of the CALS Program. The study group's objective was to determine the most advantageous mix of existing standards for application in specifying digital delivery of product data items in support of weapon system development and support contracts. The evaluation was accomplished by means of a product data requirements matrix in which types of data required by the government throughout the development process were mapped against the applicability of the various standards. A delphi approach, in which users of all of the standards participated, was used to determine applicability.

Abstract Either from a legislative point of view or because of OEM demands, the automotive industry is increasingly facing of reducing vibration & noise in the vehicle. More particularly on the engine area, the development of Gasoline and Diesel fuel components based on high pressure pumps, rails, any pipes and injectors are more and more subject of a particular NVH (Noise Vibration and Harshness) attention. The use of modern digital techniques such as 3D FEM vibroacoustic, leads to use virtual prototyping as complementary to traditional real hardware prototypes development. Among interest, number of iterative loops to reach a best design brings an important value to new product development with an optimized cost. Basically the core part of virtual prototyping is about a 3D FEM model definition for each component.

The CDIF Family of Standards is primarily designed to be used as a description of a mechanism for transferring information between CASE tools. It facilitates a successful transfer when the authors of the importing and exporting tools have nothing in common except an agreement to conform to CDIF. The language that is defined for the Transfer Format also has applicability as a general language for ImportExport from repositories. The CDIF Integrated Meta-model defined for CASE also has applicability as the basis of standard definitions for use in repositories.
