Figure shows an engine valve driven by an overhead camshaft. The rocker arm pivots about the fixed point O. For particular values of the parameters shown, the valve displacement x(t) satisfies the following equation.
10-6 + 0.3x = 5θ(t)
Where θ(t) is determined by the cam shaft speed and the cam profile. A particular profile is
θ (t) = 16 x 103(l04t4 - 200t3 + t2) 0 ‰¤ t ‰¤ 0.01
Use Simulink to plot x(t). The initial conditions are zero.
