FINITE ELEMENT ANALYSIS OF A GEAR TOOTH USING ANSYS AND STRESS REDUCTION BY STRESS RELIEF HOLE
ABSTRACT
 The main aim of this project is to model a spur gear by PRO-E. The model is then imported to ANSYS
 To reduce the stress in a gear tooth, with the help of a stress relief hole, to the minimum value, without affe ....etc

CHAPTER-1
STRESS TENSOR

INTRODUCTION:
Two planes from infinitesimal distance away and parallel to each other were made to pass through the body, an elementary slice would be isolated. Then, if an additional two pairs of planes were passed normal to the first pair, a cube of infinitesimal dimensions would be isolated from the body. Such a cube is as shown in the Fig.1.1 (a). On the near faces of the cube, i.e., on the faces away from the origin, the directions of stres ....etc

DESIGNING A FIR FILTER:
Following are the steps to design linear phase FIR filters Using Windowing Method.

I. Clearly specify the filter specifications.
Eg: Order = 30;
Sampling Rate = 8000 samples/sec
Cut off Freq. = 400 Hz.

II. Compute the cut-off frequency Wc
Eg: Wc = 2*pie* fc / Fs
= 2*pie* 400/8000
= 0.1*pie

III. Compute the desired Impulse Response h d (n) using particular Window
Eg: b_rect1=fir1 (order, Wc , 'high',boxcar(31));

IV. Convolve input sequence with truncate ....etc

Deterministic Finite State Automata

One-way, infinite tape, broken into cells
One-way, read-only tape head.
Finite control, I.e., a program, containing the position of the read head, current symbol being scanned, and the current “state.”
A string is placed on the tape, read head is positioned at the left end, and the DFA will read the string one symbol at a time until all symbols have been read. The DFA will then either accept or reject.

FINITE ELEMENT ANALYSIS ON ANGLE PLATE
ABSTRACT
The finite element method (FEM) (sometimes referred to as finite element analysis) is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. The topic of the seminar includes the study of Finite Element Analysis and a case study of finite element analysis.
A double angled web connection is modeled and analyzed to predict the behavior of the angle plate using finite element analysi ....etc

2-D DFT of two dimensional finite extent sequences.

2-D DFT and Convolution
The DFT can be computed with a fast algorithm and it is sometimes beneficial to do the convolution of two sequences A (M1 £ N1) and B (M2 £ N2) via point DFTs. Speed improvements are only possible if both sequences have large dimensions. Otherwise convolutions are better implemented via the convolution sum.

Procedure:-
1. Rewrite the difference equation so that y and its delayed samples are on the LHS
2. Create a matrix a for the coefficients of y and its delayed versions
3. Create a matrix b for the coefficients of x and its delayed versions
4. Generate impulse excitation signal delta
5. Find the response h of the filter defined by a & b coefficients , so the input impulse excitation , using filter command
6. Display the impulse response h.
