Final Year Major Project on Solar Powered Three Wheeler for Disabled Person.
The design on Solidworks and Analysis on ANSYS Multiphysics. It uses the renewable energy which is eco-friendly and very less pollution.
Design and fabrication of solar three wheeler.
Design, analysis and performance evaluation of a mechanical gyratorIjrdt Journal
The project focuses on the development of an efficient and safe system for navigation for disabled people. Such a system should enable the user to control with minimum effort and should be stable in all practical situations. A gyrator is neither a motorcycle nor a four wheeler. It is a vehicle made up of an inner frame which is encompassed and supported by two large coaxially aligned wheels. The inner frame is supported by a common axle as a result, is free to oscillate back and forth relative to outer wheels. The inherent instability has limited its potential as a commercially available vehicle. But by reducing this oscillation to an optimum value by incorporating internal braking, we could make a very stable navigation system. In order to achieve motion, a shift in the centre of gravity of the inner frame is required. Two independent electric motors provide the driving torque to gearbox which drives the large outer wheels. This unique design gives the vehicle a clear advantage over conventional 4wheeled and 2wheeled vehicles as it has zero turning radius.

RE: DESIGN REQUIREMENTS FOR STIRLING ENGINE
Dear Dr. Militzer,
In 2003 a group had previously attempted to design and construct a solar powered
Stirling engine for their design project but due to technical problems the project was
unsuccessful. After careful analysis of the problems encountered by the previous group
and discussing design challenges with our project supervisor we believe that we can
successfully deliver a working Stirling engine that can be used for classroom
demonstration. The Stirling cycle is an excellent reference for teaching thermodynamic
principles and external heat engine cycles.
In the recent ‘green-energy’ movement the Stirling cycle has received renewed interest in
the area of solar energy generation, and it is the intention of our group to help raise
awareness and promote renewable energies by demonstrating the effectiveness of the
Stirling engine. Our group has finalized the following objectives and design
requirements.
Problem Statement: To harness the power of heat and utilize the laws of
thermodynamics to efficiently generate mechanical energy.
Project Objectives: To design and construct a Stirling engine for demonstration
purposes with the ability to function via a solar heat source.
Design Criteria & Performance Objectives: The following design requirements
summarize the scope of the project and the final goals and objectives we wish to achieve.
We are confident that we can deliver a working Stirling engine that will be cost-effective,
low maintenance, safe, and of quality in design by applying heat transfer, mechanical and
thermodynamic principles.

of 5 years, if properly maintained.
Size, Weight and Complexity
· Total engine size and weight to be such that safe and easy transportation is
possible by 1 person.
· Must be mounted on a compact support structure for stability and safety.
· Will be designed for ease of maintenance and assembly.
Aesthetics & Safety
· High temperature regions must be clearly indicated.
· Engine cylinder must be equipped with a removable fitting for piston
inspection and pressure release.
Documentation
· Supporting documentation and user instructions to be provided for later usage
within the Mechanical Engineering department of Dalhousie University.
Cost & Materials
· Pending the usage of machining time and salvaged components, the prototype
is estimated to cost less than $3500. Costs will be finalized in the budget.
· Construction materials for the support frame and engine will consist mainly of
steel or aluminum, depending on cost, availability, and component purpose.
· Precision components such as pistons, piston rings, and bearings may be
purchased off the shelf or salvaged.
