MBD Simulation on a Piston Assembly

Objective:

To create a 3D model for Piston Assembly and parts are performed a motion analysis and also to study linear displacement of the Piston head assembly.

Introduction:

A piston is a component in reciprocating pumps, engines, gas compressor, and other similar mechanisms. It is a linearly moving component that is contained in the cylinder and made gas-tight with the help of piston rings. In an engine, its primary function is to compress the fuel and transfer the forces from expanding gases through a connecting rod.

Parts required for assembly:

1.Piston:

2.Crank:

3.Connecting Rod:

4.Wrist Pin:

5.End Cap:

Motion Analysis:

The motion analysis going to be carried out in three different conditions,

Sl.No	Wrist Pin Offset `	Crank Speed (Rpm)
1	"0" mm	2000
2	10 mm Positive	2000
3	10 mm Negative	2000

Case 1:Motion Analysis "0" mm offset

Case 2: Motion Analysis for "10mm Positive" offset

Case 3: Motion Analysis for "10mm Negative Offset"

Conclusion:

We can conclude that Linear Displacement increases as we move from negative wrist pin offset to positive wrist pin offset i.e. the magnitude of the Linear displacement increases.
