Cam-Driven Fourbar Slider With Motion Functions Applied to the Output Link
Given: A cam-driven fourbar crank-slider with the geometry shown in Figure 16-3 is driven by a cam with a constant velocity motion program similar to that developed in Example 8-12 and Figure 8-42. The slider is the end effector and must chase a constant velocity conveyor for at least 6 inches at 10 in/sec with minimal velocity error and then return to the start position to repeat the cycle. The motion functions are applied to the slider and converted to modified functions to be applied to the cam-follower arm with a modified contour cam running at 1 Hz.
Compare the displacement, velocity, and acceleration functions between the cam follower (link 2) and the end effector of the linkage (link 4) and compare the cam profile for this solution to that of Example 16-1.
