2What 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.DemoExample
3What 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.DemoExample
4What 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.DemoExample
5Why 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.DemoExample

16Let us go throughan exampleto see how CARScan be used to solve atypical automotiveproblem....
17Make the UltraLight lighter... Problem:Reduce the mass of the front rail andmaintain axial capacity.CARS Solution:Drive through the CARS 2005 model to make required design changes, meet structural requirements, and still reduce mass.
18The front rail is joined directly to the rocker. 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.
19UltraLight front railt = 1.3 mmt = 1.55 mm51 mm75.35 mm75.35 mmCan the hat section be replaced by the hexagonal section while achieving mass reduction and maintaining strength?We will use CARS to find out...
20Information on the equations and design procedures used in this example can be accessed using the online Automotive Steel Design Manual...
21First we pick a material from the CARS material database to be used as the default material for all further analyses.
22Use GAS to compute the nominal properties of the hat section.
23The mass of the hat section (Area. length The mass of the hat section (Area * length *mass density) is computed to be 1.16 kg, using t = 1.55 mm
24Also compute the effective properties of the hat section...
25The effective properties under axial load are calculated using the material properties from MAP.
26These nominal and effective properties will be transferred to the CARS design procedures.
27Use a CARS 2005 design procedure to calculate the axial capacity of the front rail.
28We will use the calculated gas results in the design procedure.
29Use the effective properties to compute the axial capacity for the hat section.
30Repeat the calculations for the hexagonal section. Compute the nominal properties.
31The mass of this member (Area. length The mass of this member (Area * length * mass density) is computed to be 1.07 kg, using t = 1.3 mm
33The effective properties for the hexagonal section are used to compute the axial capacity of the member.
34Summary HAT Section: HEXAGONAL Section: Thickness: 1.55 mm Axial Capacity: ,800 NMass: kgHEXAGONAL Section:We find that the hexagonal section can effectively replace the hat section.Thickness: mmAxial Capacity: ,200 NMass: kg
35We have achieved a mass reduction of 8% and maintained the axial capacity by following the CARS design procedures.
