Question

Acceleration Analysis 1) (50 points) The figure below shows a walking beam mechanism. What is the angular velocity of input crank 2 (in RPM) to move 5 boxes per second? Calculate and plot the acceleration Aout (horizontal acceleration) for one revolution of the input crank 2 rotating at that velocity.

Explanation / Answer

%% Walking Beam Problem clear all; close all; clc; %% Variables a=1; b=2.06; c=2.33; d=2.22; p=3.06; gamma=31*pi/180; theta2= zeros (360,1) %% Main Program for i=1:361; theta2(i)=(i-1)*(pi/180); r=d-a*cos(theta2(i)); s=a*sin(theta2(i)); f2=r^2+s^2; delta=acos((b^2+c^2-f2)/(2*b*c)); g=b-c*cos(delta); h=c*sin(delta); theta3(i)=atan2(h*r-g*s,g*r+h*s); xp(i)=a*cos(theta2(i)+p*cos(theta3(i)+gamma)); yp(i)=a*sin(theta2(i)+p*sin(theta3(i)+gamma)); end plot(xp,yp,'color','r') grid on title ('title') xlabel('title') ylabel('title')
