Shock absorber is a mechanical device designed to smooth out
or damp shock impulse, and dissipate kinetic energy.
In a vehicle, it reduces the effect of traveling over rough ground,
leading to improved ride quality, and increase in comfort due to
substantially reduced amplitude of disturbances.
In this project suspension system is design and a 3D model is
create using Creo.
The model is also change by changing the thickness of the
3. Structural analysis and modal analysis are will do on the shock
absorber by varying different spring materials.
Spring materials are Spring Steel, Phosphor bronze, Beryllium
Copper and Titanium alloy.
To validate the strength of the model, the structural analysis on
the helical spring was done.
The analysis is done by considering loads, bike weight, and
single, double riding.
Finally comparison is done for different materials to verify best
material for spring in Shock absorber. Modeling is in Creo and
analysis is in ANSYS.
A shock absorber or damper is a mechanical device designed to smooth
out or damp shock impulse, and dissipate kinetic energy.
Shock absorbers are an important part of automobile and motorcycle
suspensions, aircraft landing gear, and the supports for many industrial
Large shock absorbers have also been used in structural engineering to
reduce the susceptibility of structures to earthquake damage and
A transverse mounted shock absorber, called a yaw damper, helps keep
railcars from swaying excessively from side to side and are important in
passenger railroads, commuter rail and rapid transit systems because they
prevent railcars from damaging station platforms.
5. Shock Absorber types
There are a number of different methods of converting an impact
/collision into relatively smooth cushioned contact..
Collapsing safety Shock Absorbers
Self compensating Hydraulic
