In this Smart Materials A view towards Shape Memory Alloy Mech Paper a  comparative study between SMA’s and other generally used materials or alloys is made , with the help of live examples (aircraft maneuverating, robotic muscles and human bone plates),

Smart materials are one among those unique materials, which can change its shape or size simply by adding a little bit of heat, or can change from a liquid to a solid almost instantly when near a magnet. These materials include piezoelectric materials, magneto-rheostatic materials, electro-rheostatic materials, and shape memory alloys (SMA’s).  Shape memory alloys (SMA’s) are metals, which exhibit two very unique properties, pseudo-elasticity (an almost rubber-like flexibility, under-loading), and the shape memory effect (ability to be severely deformed and then return to its original shape simply by heating).

Advantages:

• Biocompatibility.
• Diverse Fields of Application.
• Good Mechanical Properties (strong, corrosion resistant).

Disadvantages:

• Relatively expensive to manufacture
• Have poor fatigue problem
• Cannot survive for more cyles unlike a steel component.

CONCLUSION:

The SMA’s discussed in this project are supposed to have a major say in the field of precision engineering and surgical operations in years to come. The sensing and responding property of these materials make them analogous to human brain and muscular system.

The SIX SIGMA Quality Improvement Program Mechanical Final Seminar Topic presents an overview of the process which explains how SIX SIGMA increase the overall quality improvement task into a series of project management stages.

The main objective of any business is to make profit. For increasing the profit, the selling price should increase and/or the manufacturing cost should come down. Since the price is decided by the competition in the market, hence the only the way to increase the profit is to cut down the manufacturing cost which can be achieved only through continuous improvement in the company’s operation. Six sigma quality programs provide an overall framework for continuous improvement in the process of an organization. Six Sigma is a smarter way to manage business or department. It is a vision of quality that equates with only 3.4 defects for million opportunities for each product or service transactions and strives for perfection.It uses facts, data and root cause to solve problems

CONCLUSION:

The project aims at continuous improvement in all the process within the organisation to give zero-defect production and thus have the more return on investment with best results.

The Ship with Wind Mills Mechanical Engineering Seminar aims at bulding Ship With Wind Mill to use its energyu and generate power out of it at a very economical price.

Wind energy,one of the non-conventional sources of energy  can be utilized to run wind mills to produce electricity. The latest technologies of wind mills say that the offshore wind mills have high out put. This is because offshore is free from obstacles and full of non-stop high speed winds. The power developed by the wind mills is said to be depend on the cube of velocity of air that passes through the turbine. Offshore wind mills have only for the 97% of time, which means the technology is yet to develop to be more efficient.

So problem is not having wind for 100% of time, and the solution to the problem is SHIP WITH WIND MILLS. This is the ship which will carry wind mills into the open sea and add its velocity component to the wind so as to get wind for 100% of time. When calculations are made it is found that this method is generating power such that ,  a fraction off out put is sufficient to run the ship and the left over power can be made use of

CONCLUSION:

The project projects on reaching the high demands of the rapidly developing generation to be as efficient as possible. It gives the way to productively utilize freely available air and generate power out of it.

This Robotics Mckibbens Muscle Latest Mech Seminar on the design of a biorobotic actuator, i.e soft arms for robots to prevent them from damage.

Industrial robots, which are  heavy moving bodies, show high risk of damage when working and also sessions in dense environment of other robots. This initiated the allure for lighter robot constructions  using soft arms which create powerful, compact, compliance and light robotic arms and consist of pneumatic actuators like McKibben muscles. Data from several vertebrate species (rat, frog, cat, and human) are used to evaluate the performance of a McKibben pneumatic actuator.

The MnKibben muscles use Electro Active Polymers (EAP) as sensors, which simplify a robotic finger models by acting like an actuator (sensor cum actuator). Ion-exchange Polymer Metal Composite (IPMC). Even these are dicussed in this project in detail.

The project presents solutions to certain problems in the McKibben muscles.Adroit use of the solutions provided in this project abets researchers to produce highly efficient artificial muscles system which consume “less energy & oxygen” than a natural one. Therefore “World’s Most Energy Efficient Robot” is discussed in this project with its innovative ideas.

Advantages Of The Mckibben Artificial Muscle

It has high force to weight ratio Size availability, Flexible, Powerful, Damped, Effective, Lightweight, Low-cost  and Smooth.

CONCLUSION:

The project provides the potential  to emulate the resilience and fracture tolerance of biological muscles, that give space robots animal-like flexibility and manipulation ability based on a simple, light-weight strip of highly flexible plastic that bends and functions similarly to human fingers when electrical voltage is applied to it. McKibben artificial muscles can be used to develop Biorobotic arms for handicaps. Artificial muscles Years from   now,  the  McKibben   muscles  could  also  conceivably   replace   damaged  human muscles, leading to partially “bionic men” and “bionic women” of the future.

The Pollution Less Engine The Sterling Engine Mechanical Seminar Paper aims at developing working model of a Pollution Less Engine, The Sterling Engine and gives the classification of different types of Sterling Engines.

The quest of human beings to develop engines with high power, high torque, less vibration and most essentially with no pollution is on since the discovery and development of engine. Stirling engine is just one step forward towards the creation of a noise free and pollution less engine.

The Stirling engine is the engine, which uses a fixed amount of gas sealed inside a cylinder. The expansion and contraction of the gas, using heat from external source, creates the useful work. The main advantage of this engine is its capability to use any type of fuel and the emission of no exhaust gases.

Stirling engine shows a greater potential over any other type of engine existing today.

• There is no exhaust of gases as in case of normal piston engines.
• These engines are quieter in operation.
• Gas inside the engine never leaves the engine.
• The external heat source could be anything-even heat from our hand.
• No combustion takes place inside cylinder of engine. Hence there is no explosion.

This Neural Networks in Advanced Manufacturing Technology proposes a method of intelligent controlling of injection molding using Neural Network based control unit.

Neural Networks offer pattern recognition based intelligent control. They process data in a parallel manner and thus they are very fast.Since neural networks learn solely based on training data it is possible to obtain inverse models of manufacturing process by simply obtaining the training data from a process model and presenting it to the neural networks in an inverse manner.

This simulation of neural network control scheme may be done by using soft wares like MATLAB, TG MOLD etc, This  project  uses “FORWARD MODELLING”of neural   network .

The aim is to identify the feasibility of obtaining an intelligent control scheme that can learn the inverse model of a manufacturing process and react in a real-time to take corrective actions during fabrication.

CONCLUSION:

The project demonstrates the capabilities of this process model/Neural Network based control unit in several experiments that integrate the control method with a reliable flow progression sensing sub system .

This Nano Technology and Prototyping Mechanical Seminars provides a brief overview of the problems and benefits created by Nanotechnology, and substantiates the claim that a variety of ethical systems will be necessary to deal appropriately with the range of issues raised by nanotech.

Any organization has an explicit or implicit code of ethics: rules that its members are expected to follow. There are at least three ethical systems that are commonly used to administer different types of resources. Resources that can be traded to mutual benefit are best administered with Commercial ethics, which include honesty and efficiency. Things that can be freely duplicated, producing unlimited benefit, are best handled with Information ethics, which maximize the accessibility and utility of such resources.

Nanotechnology presents a wide range of problems and opportunities by making most existing products quite a bit more powerful and flexible.It promises to bring about abundance and rapid improvement of technology at low cost and high convenience.

CONCLUSION:

Hence, the project throws light on  the power of Nanotechnology as a technology, then surveys the risks, commercial opportunities, and abundance that may be created by nanotech and also the need for the deliberate development of collaboration between diverse organizations with radically different ethics.
