Design and development of Active suspension system for a motorbike
Project Area of Specialization Computer ScienceProject SummaryDamping is very important phenomena in which energy is dissipated. This phenomenon is used in dampers in vehicles to dissipate the kinetic energy which is absorbed during running of vehicle on road.
The project is an active suspension system which will vary the damping of the damper according to the road conditions using sensors and will be implemented on a motorbike.
The damping will be varied by using a control plate which will control the damper oil passage within the damper according to the data received by sensors thus providing the passenger with ride comfortability.
The main feature that makes this project distinct and one of its kind is that this damper is very low cost. The phenomena of active suspension is used in racing and luxury cars like Audi and BMW and a single damper costs about 200000 PKR. Our project serves as low cost alternative to those dampers as low as one third of the cost. It can also be implemented in commercial cars and heavy Bikes.
Project Objectives- Designing and fabrication of an active suspension system.
- To develop very low-cost active suspension system as compared to other active suspension systems and provide ride comfortability.
- To use non toxic oil in the active suspension system.
4.To implement it on a motorbike.
Project Implementation MethodThe project which is a shock absorber will be implemented on the front wheel of the bike. It will replace the front two shocks by a single shock. The position of the shock will be between the front wheel and the bike handle with a constraint length. Beside it a sensor (profilometer or accelerometer or ultrasonic) will be implemented in such a position that it can easily read the road details or road waviness.
Two parallel plates will be used to hold the shock absorber above the front wheel in a right position. This project will be implemented manually and mechanically.
Benefits of the Project- Ride Comfortability
The project us an active suspension system in which the damper used will vary the damping according to the roughness of the road that is on a bumpy road the damper will become hard so that the passenger does not feels the jerks similarly on a smooth road the damper will become soft and all this will be happening automatically thus providing ride comfortability.
- Low Cost and Integral
The active suspension system is used in luxury and racing cars like AUDI and BMW which is very expensive. A single damper cost about 200000 PKR. Our project uses same active suspension concept but is low cost as low as one third of the original cost and with slight alterations can be integrated into commercial vehicles.
Technical Details of Final DeliverableThe working principal of this damper will be same as others damper.
Generally dampers are twin tubes but we are working on mono tube.
Xp = Xr - Xt
Final Equation
The damping of this project will be vary by using different configuration of control plate. We have three configuration with different cross sectional area for the flow of the fluid.
Configuration 1:
Diameter of hole 1
number of hole
Configuration 2:
Diameter of hole 2
number of holes
Configuration 3:
Diameter of hole 3 =
number of holes
Calculation for the thickness of the control plate is done by using bending stress analysis.
Z=
As we know that only 44% of weight is acting on the front wheels so
t = 2.76mm ? 3mm.
