MBD Simulation on a Piston Assembly
AIM:- To design the 3d model of the parts of piston and then to assemble them.
Then perform motion analysis three different conditions.
| Sl.No |

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings.
The main parts of the piston are:-
1.crank

2.piston head

3.connecting rod (cr)

4.wrist pin

5.End cap

now case 1.
when the wrist pin ofset is 0mm

Plot of Linear Displacement of Piston Assembly(offset is 0)

plot angular velocity of Piston Assembly(offset 0)

case 2 .
Wrist pin Offset Is 10 mm positive

plot of angular velocity of Piston Assembly (10mm Positive Offset)

plot of Linear Displacement of Piston Assembly(10mm Positive Offset)

case 3
Piston assembly (10mm negative Offset)

plot of angular velocity of Piston Assembly (10mm Negative Offset)

plot of Linear Displacement of Piston Assembly(10mm Negative Offset)
