SLIDER CRANK MECHANISM - MBD

NOUVELLES LIÉES

Description Générale

The Slider Crank Mechanism, "MBD", designed by EDIBON, is an example of slider-crank mechanism.

This mechanism is made of aluminum and consists of a rotary element (graduated disc), called crank, connected to a rigid bar, calledconnecting rod. When the crank rotates, the connecting rod moves backwards and forwards.

The input angle is set on the ball bearing mounted crank disc and read on an angle measuring scale. A millimeter scale is fitted for thelinear motion of the connecting rod. The "MBD" unit includes two connecting rods of different length so that they can be compared.

EXERCICES GUIDÉS INCLUS DANS LE MANUEL

  1. Demonstration of the action of a simple in-line slider-crank mechanism.
  2. Study of the relationship between the linear displacement of the sliding block (connecting rod) and the angular displacement of the rotary element (crank).
  3. To illustrate graphically and study the effect of changing the length of the connecting rod.
  4. Determination of the velocity and acceleration of the sliding block by graphical differentiation and compared with the values obtained by equations of motion or by velocity and acceleration diagrams.
