Quick Return Motion Mechanism
The given figure shows a quick return motion mechanism in which the driving crank OA rotates at 120r.p.m. in a clockwise direction.
Acceleration of Block D
For the position shown, the acceleration of block D can be determined as follows:
- Draw the velocity and acceleration diagrams for the mechanism.
- From the velocity diagram, it can be observed that the velocity of block D is perpendicular to the slotted bar QB.
- Therefore, the acceleration of block D is equal to the component of the acceleration of point Q along the slotted bar QB.
- The acceleration of point Q can be determined from the acceleration diagram.
- Using trigonometry, the component of the acceleration of point Q along the slotted bar QB can be calculated.
- This component is the acceleration of block D.
- The direction of the acceleration of block D can be determined by considering the direction of the component of the acceleration of point Q along the slotted bar QB.
Angular Acceleration of Slotted Bar QB
The angular acceleration of the slotted bar QB can be determined as follows:
- From the velocity diagram, it can be observed that the velocity of point Q is perpendicular to the slotted bar QB.
- Therefore, the angular acceleration of the slotted bar QB is equal to the component of the angular acceleration of point Q along the slotted bar QB.
- The angular acceleration of point Q can be determined from the acceleration diagram.
- Using trigonometry, the component of the angular acceleration of point Q along the slotted bar QB can be calculated.
- This component is the angular acceleration of the slotted bar QB.
- The direction of the angular acceleration of the slotted bar QB can be determined by considering the direction of the component of the angular acceleration of point Q along the slotted bar QB.
In conclusion, the magnitude and direction of the acceleration of block D and the angular acceleration of the slotted bar QB can be determined by analyzing the velocity and acceleration diagrams of the mechanism.
