Let us go throughan example

to see how CARScan be used to solve a

typical automotiveproblem....

Make the UltraLight lighter...Make the UltraLight lighter...

Problem: Reduce the mass of the front rail and maintain axial capacity.

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

CARS Solution:

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.

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...

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

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

Use GAS to compute the

nominal properties of

the hat section.

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

Also compute the effective properties of

the hat section...

The effective properties under axial load are

calculated using the material properties from MAP.

These nominal and effective properties will be transferred to the CARS design procedures.

Use a CARS 2005 design procedure to calculate the axial capacity of the front rail.Use a CARS 2005 design procedure to calculate the axial capacity of the front rail.

SummarySummary

HAT Section:

HEXAGONAL Section:

Thickness: 1.55 mm

Axial Capacity: 151,800 N

Mass: 1.16 kg

Thickness: 1.3 mm

Axial Capacity: 154,200 N

Mass: 1.07 kg

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

We have achieved a mass reduction of 8% and maintained the axial

capacity by following the CARS design procedures.
