Aim: Write A Computer Program For Velocity and Acceleration Analysis of Slider Crank Mechanism. Software Used: MATLAB R20

The document describes Experiment No. 2 which analyzes the velocity and acceleration of a slider crank mechanism using MATLAB. It involves writing a computer program that takes user inputs for the crank radius, crank angle, connecting rod length, and crank speed in RPM to calculate the displacement, velocity, and acceleration of the piston. The program outputs the results for sample input values.

Velocity and Acceleration Analysis of Slider Crank Mechanism

Aim: Write a Computer Program for Velocity and Acceleration


Analysis of Slider Crank Mechanism.
Software Used: MATLAB R20
Code:
r=input ('Enter radius of crank in mm=');
ang=input ('Enter the crank angle in Degree =');
l=input('Enter the length of connecting rod in mm=');
n=l/r;
N=input('Enter the speed of the crank in RPM=');
j=sind(ang);
j2=sind(2*ang);
k=cosd(ang);
k2=cosd(2*ang);
w=(2*pi*N)/60;
x=r*(((j*j)/2)+(1-k));
v=r*w*((j2/2)+j);
a=r*w*w*((k2/2)+k);
fprintf('Displacement of Piston is %f mm\n ',x);
fprintf('Velocity of Piston is %f mm/s\n',v);
fprintf('Acceleration of Piston is %f mm/s^2\n',a);
Output:
r=input ('Enter radius of crank in mm=');
ang=input ('Enter the crank angle in Degree =');
l=input('Enter the length of connecting rod in mm=');
n=l/r;
N=input('Enter the speed of the crank in RPM=');
j=sind(ang);
j2=sind(2*ang);
k=cosd(ang);

v=r*w*((j2/2)+j);
a=r*w*w*((k2/2)+k);
fprintf('Displacement of Piston is %f mm\n ',x);
fprintf('Velocity of Piston is %f mm/s\n',v);
fprintf('Acceleration of Piston is %f mm/s^2\n',a);
Enter radius of crank in mm=180
Enter the crank angle in Degree =40
Enter the length of connecting rod in mm=720
Enter the speed of the crank in RPM=300
Displacement of Piston is 79.297832 mm
