SEM327: Dynamics of Machines- Mechanical Assignment

Question:

Part A) Planar Kinematics:

You are asked to design a slider crank and rocker mechanism such that you achieve a slider movement output of: x(t)=D=0.2(1-cos?),where ? is the angle of the input crank relative to the horizontal axis.The center of the input crank, ??, is given for the mechanism as 1m from the slider horizontally when the shaft is vertical and the slider is on the same vertical alignment (as per an in-line slider mechanism). The input shaft rotates clockwise at a fixed 600 revolutions per minute.The rocker is to be connected to the slider and needs to be designed such that the end moves in a 2m radius curve through an angle of +/-30°.Give a complete analysis of the systems translational and rotational velocities, accelerations and positions of all components. Detail in a report all assumptions and relevant information about the system. Give a complete detailed understanding of system.

Part B) Vibrations and dampeners:

A mass of 10kg is suspended on a spring and is it found that when it oscillates the amplitude reduces to 50% of the initial value after 5 oscillations over a period of 3 seconds. Design a dampener such that the amplitude reduces to 10% of the initial after 2 oscillation with the same initial frequency. Detail in a report all assumptions and relevant information of the system. Give complete detail understanding of system.
