Agenda

• Getting Access to the Software and Resources

• Running simulations with the FSAE database

• Modifying the template to represent your Car

• Conducting a Design Study

• Questions

Suggested Strategy for Getting Started

4


Getting Started Tutorials

Select Adams Help from the Help menu then navigate to the getting started

section. Though the demo vehicle appear much more elaborate than the

FSAE model, they are actually very similar, and the Getting Started tutorials

are directly applicable to the FSAE template for the most part.

5


Using the FSAE Database

• Register on mscsoftware.com to get access to SimCompanion

• Visit the article “Using the special FSAE database with MD Adams/Car 2010” at

http://simcompanion.mscsoftware.com/infocenter/index?page=content&id=KB8019488

• Download the template files follow the instructional .pdf



6


How to Get Help

• Help Docs• Start at the TOC and work down to your topics

(Remember PostProcessor is under Adams Basic Package)

• Use Context Help (F1 in appropriate text boxes)

• Text Search/Index

• SimCompanion• Search SimCompanion for Keywords

• VPD Forums• Search for posts for similar issues

• Post in Adams University Section

• Technical Support• Have your Designated Contact email Technical Support at

[email protected]

Types of Simulations

Suspension Testrig

Full Vehicle Simulation

8


Suspension Testrig

• Kinematic Analysis

• Bump (Parallel)

• Roll (Opposite)

• Steering (None, Fixed,

Free, Controlled)

• Dynamics Analysis

9


Suspension Results Analysis

• Analyze Results

• Display Animations

• Graph Results

10


Full Vehicle Simulation

• Predefined Analysis

• Basic Maneuvers

• Acceleration

• Braking

• Maintain Steer Angle

• Some Combination of

Above

• Closed Loop

• Maintain Specified

Radius

• Achieved Specified

Acceleration

11


Full Vehicle Simulation (cnt’d)

• User Defined Simulations

• Event Builder - Define

maneuvers with open

loop constants/functions

or closed loop objectives

• Road Builder – Define

Custom roads for path

optimization and

SmartDriver

12


Modifying Your Vehicle

• Hardpoints

• Masses

• Property Files

• Tires

• Shocks

• Powertrain

• Aero Forces

• Adding/ Removing /Modifying Parts, Joints, etc.

• Swapping Subsystems

• Modifying Templates

13


Hardpoints

• Most Define the Center or Axis of a Rotational Joint

• Defines Geometries

• Mirrored

• Edit in table editor

• Listed in .sub file

14


Property Files

• Tires

• PAC2002 FSAE property files available from TTC

http://www.millikenresearch.com/

• Springs/Dampers

• Curve Editor

• Property Files

• Drivetrain/Powertrain

• Engine Torque Curve

• Differential Property File

• Engine/Transmission Parameters

15


Mass and Setup Parameters

• Right Click >> Modify to Change Mass

• Mass can be calculated using geometry and

custom density

• Suspension Setup Parameters used for certain

Analysis/Results

16
