Mathematical modeling of Mechnical system


Time domain analysis


The dynamic behavior of a system is judged under application of standard test signals –
an impulse,
a step,
a constant velocity (Ramp), and
constant acceleration (Parabolic).

The output of the system for time domain signal (time dependent signal) is called as time response.

The time response of any system has two components: transient response and the steady-state response.

INTRODUCTION
Tunnel Boring Machine (TBM) also known as ‘MOLE’.
It is used to excavate tunnels with a circular cross section.
It can bore through anything from hard rock to sand.
Different types of TBMs are used for different geotechnology.
Used as an alternative to drilling and blasting (D&B) methods and conventional 'hand mining' in soil
Limits the disturbance to the surrounding ground and produces a smooth tunnel wall.
Suitable to use in heavily urbanized areas.
TBMs is also a complete ....etc

hi , this is samurai007 and i would like to get a detailed presentation on the topic TUNNEL BORING MACHINE. I need to give a powerpoint presentation on a mechanical related topic and i think this topic fulfills my needs.
Please cover following topics-
1. working
2. applications fields (elaborate)
3. advantages and disadvantages
4. latest developments
5. comparison with old traditional methods. etc.

I am expecting a detailed presentation or an elaborate content (must include pictures)

THANKS......... ....etc

ABSTRACT
For centuries now, wind tunnels have been a key element in scientific research in a number of fields. Experimenting with racecars, airplanes, weather patterns, birds, and various other areas has been made much easier because of its development. In the racing field, for example, the information gathered from this testing can mean the difference between winning and losing a race. Weather simulations can also provide valuable information regarding building stability and safety. This has become very important wh ....etc

CONTEXT
A Tunnel Boring Machine (TBM) also known as a mole” is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They can bore through anything from hard rock to sand. Tunnel diameters can range from a metre (done with micro-TBMs) to almost 16 metres to date. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling rather than TBMs.
Tunnel boring machines are used as an alt ....etc

Relative roles of CFD and wind tunnel testing in the development of aircraft

Introduction
CFD
CFD is computational technology that enables us to study the dynamics of things that flow.
Using CFD, a computational model that represents a system or device that we want to study is built. Then we apply the fluid flow physics to this virtual prototype, and the software outputs a prediction of the fluid dynamics.

Application
fluid flow, heat transfer , mass , phase change , chemical re ....etc

ABSTRACT
We have designed an electronic circuit for the automatic illumination of tunnel.
Our main objective for the circuit is to reduce the idle time power consumption of
lights in tunnel. According to the traffic density and light intensity outside the
tunnel we have prepared a model which dims or turn the lights of during the idle
time of the tunnel for saving the power consumption. In this project our main
focus is on the power saving and illumination optimization.
