MBD Simulation on IC Engine Valve Train

AIM:- Design IC Engine Train Valve and check the Motion Study

OBJECTIVE:- A valve Train is a mechanical system that controls operation of the intake and exhaust valve in an internal combustion engine. The intake valve controls the flow of air/fuel mixture (or air alone for direct-injected Engines) into the combustion chamber, while the exhaust valves control the flow of spent exhaust gases out of the combustion chamber once combustion is completed

BODY:-

STEPS TAKEN TO DESIGN AND SIMULATE THE ENGINE.

1. First, we have to design a model of all parts of the assembly in Solidworks.
2. Design CAM ENgine for two different conditions.
3. Then we have to assemble all of the 5 parts in both conditions. Specific way or with corrects mate.
4. For an assembly enable visible the axis for a proper mate.
5. After the assembly, we have to switch from animation to Motion analysis.
6. Before going to motion analysis we first use move component command.
7. In move command, there is an option for physical damage.
8. Use this command due to this all farts are set to their position, and it is a very useful command.
9. Apply material Cast Iron in both conditions
10. For motion analysis, we should cross-check that solid works Motion enable or not.
11. First, we have set a motor at the axis of the piston motor with RPM 1500.
12. Then we use contact command set relation between two bodies
13. First, we have set contact relation between CAM ENGINE and PUSH ROD
14. Then we have set contact relation between PUSH ROD and CRANK ROCKER
15. And the last contact between VALVE ENGINE and CRANK ROCKER
16. Then we have to set spring between them
17. Set gravity in Y- direction
18. After Calculating it gives result but not proper for this we have to apply the material on all the component
19. Plot two graph b/w. TIME AND LINEAR DISPLACEMENT for two different positions.
20. Plot the Graph for both conditions.
21. After clicking show plot clicks on export to a spreadsheet.
22. To export the spreadsheet for both positions.

CONCLUSION:-

A valvetrain or valve train is a mechanical system that controls the operation of the intake and exhaust valves in an internal combustion engine
