2. INTRODUCTION
In a vehicle system, the suspension along with
the tyres is an important component, since it is
responsible for the transmission of loads, along
with the tyre and road contact forces.
However, both of ride comfort and vehicle
handling requirements are conflicting while
designing a vehicle suspension.
Therefore it is very difficult to maintain high
standard of ride comfort and vehicle handling
simultaneously under all driving condition.
Designer of suspension system always has to
compromise between ride comfort and vehicle
handling to optimize the suspension system.

3. 

Purpose of the suspension system is to improve
the ride comfort as well as Vehicle handling of the
vehicle. However, both of ride comfort and vehicle
handling requirements are conflicting while
designing a vehicle suspension.
Therefore it is very difficult to maintain high
standard of ride comfort and vehicle handling
simultaneously. In order to positively influence
both simultaneously, primary suspension and
cabin suspension terms are introduced
Problem definition:

4. OBJECTIVE:
•
•
The objective for this work is to study and develop
a test facility that can improve the state-of-the-art
in indoor vehicle suspension simulation testing on
a quarter-car vehicle.
The objective is to design and develop a quarter
car suspension test rig model and to also perform
its simulation.

5. Experimental analysis carried by
other researchers:
Experimental and theoretical results obtained are nearly same
Comparison with MATLAB simulink simulation results
Acceleration responses are obtained with FTT analyzer
Road surface excitations by electromagnetic shaker
Hyundai Elantra 1992 for sinusoidal road profile
Quarter car vehicle model with linear and non-linear parameters is
developed

6. Experimental analysis carried
by other researchers:
Experimental and theoretical results obtained were nearly close.
Analysis on various speeds of 10, 20, 30, 40, 50, 60 kmph
Experimental setup with I beam structure was developed
Testing on different speeds and Road profile, body travel, body acceleration and
suspension deflection output received
Mathematical modeling of quarter car model and simulation on MATLAB
Objective: To design and develop quarter car suspension test rig model and perform
simulation

7. DESIGN DESCRIPTION:
A suspension
testing machine
was designed by
taking suitable
assumptions on
CATIA.
(though the
calculations are
yet to be verified
through analysis
software)

8. Other Proposed designs for the
suspension testing machine:
A pneumatic type suspension system
can also be designed, but it may
increase the cost of machine.
