slide2

What is CARS 2005?

  • Computerized Application and Reference System.
  • A computerized version of the Automotive Steel Design Manual (ASDM).
  • Brings together material, design and manufacturing information for automotive designers and engineers.

Example

Demo

slide3

What is under the hood?

The CARS engine consists of:

  • Application Mode - Provides numerical and graphical solutions to the design procedures and equations found in the ASDM.
  • Reference Mode- Quickly and selectively presents the information found in the ASDM.

Example

Demo

slide4

What are CARS 2005 accessories?

  • GAS - Geometric Analysis of Sections,Enhances the power of the CARS engine, by calculating geometric section properties for arbitrary thin-walled sections.
  • MAP- Material Archive Program,Provides easy access to the most frequently used automotive steels, with a full selection of material properties.
  • KEY- Key to Auto Steel Design,Simplifies CARS startup and operation with automatic selection of design procedures.

Example

Demo

slide5

Why should you drive CARS 2005?

  • CARS solves complex design problems and increases speed and accuracy of the design process.
  • Reduces the possibilities of errors and increases productivity by simplifying calculations.
  • Provides immediate access to reference material.
  • Helps make the most effective use of steel.

slide16

Let us go through

an example

to see how CARS

can be used to solve a

typical automotive

problem....

slide17

Make the UltraLight lighter...

Problem:

Reduce the mass of the front rail and

maintain axial capacity.

CARS Solution:

Drive through the CARS 2005 model to make required design changes, meet structural requirements, and still reduce mass.

slide18

The front rail and its connection to the body have a great influence on load transfer.

A new UltraLight front rail was created to improve the load transfer by distributing the load along three paths.

The front rail is joined directly to the rocker.

The dash cross member transfers loads cross-car.

The front rail extension carries some of the load directly to the front floor cross member.

slide19

UltraLight front rail

t = 1.3 mm

t = 1.55 mm

51 mm

75.35 mm

75.35 mm

Can the hat section be replaced by the hexagonal section while achieving mass reduction and maintaining strength?

We will use CARS 2005 to find out...

slide20

Information on the equations and design procedures used in this example can be accessed using the online Automotive Steel Design Manual...

slide21

First we pick a material from the CARS material database to be used as the default material for all further analyses.

slide23

The mass of the hat section (Area * length *mass density) is computed to be 1.16 kg, using t = 1.55 mm

slide25

The effective properties under axial load are calculated using the material properties from MAP.

slide31

The mass of this member (Area * length * mass density) is computed to be 1.07 kg, using t = 1.3 mm

slide33

The effective properties for the hexagonal section are used to compute the axial capacity of the member.

slide34

Summary

HAT Section:

Thickness: 1.55 mm

Axial Capacity: 151,800 N

Mass: 1.16 kg

HEXAGONAL Section:

We find that the hexagonal section can effectively replace the hat section.

Thickness: 1.3 mm

Axial Capacity: 154,200 N

Mass: 1.07 kg

slide35

We have achieved a mass reduction of 8% and maintained the axial capacity by following the CARS design procedures.

slide36
