1. ME 143 VEHICLE DESIGN Vehicle Suspension Simulation with Nastran4D Jeffrey H. Cho

2. Problem Statement  Creates 3D vehicle suspension parts in SolidWorks, then utilize Nastran4D for dynamic system modeling.

3. SolidWorks Parts Vehicle: 1969 Chevrolet Camaro

4. SolidWorks Parts Upper Control Arm

5. SolidWorks Parts Lower Control Arm

6. SolidWorks Parts Rotor

7. SolidWorks Assembly

8. Nastran4D Export  Use MSC.visualNastran tool to export parts from SolidWorks to Nastran4D

9. Nastran4D Assembly  Revolute joint constraint allows proper relative movement of upper control arm relative to vibration input. Only one is necessary.

10. Nastran4D Assembly  Revolute joint constraint allows proper relative movement of lower control arm relative to vibration input. Only one is necessary.

11. Nastran4D Assembly  Revolute joints allow rotor to properly pivot between upper and lower control arms.

12. Nastran4D Assembly  Spring / Damper System –Spring Force:1000 ft/lb –Damper Force:900 lb*sec/ft

13. Nastran4D Assembly  Input force: 800 lb –Initially active, then relaxes after 0.2 sec at which point the spring / damper restore equilibrium.
