1. Valve Cam Exercise Problem Statement Open Valve_Cam.sldasm The valve cam model pictured above includes a spring that will be added between the valve guide and the valve. The camshaft will be rotated at an angular velocity of 36,000 deg/s. Define Moving and Ground parts. Using curve/curve contact, create a spring with the correct stiffness and free length so that the camshaft and rocker are always in contact. We are going to plot the: Cam and Rocker contact force Valve and Rocker contact force Valve and cam contact force

2.  Define Moving and Ground Parts Valve_Cam.sldasm valve valve_guide rocker_shaft rocker shaft_mount camshaft Valve Cam Exercise

3.  Add Revolute Motion Angular Velocity = 36,000 deg/s Valve Cam Exercise

4.  Add Curve/Curve Intermittent Contact Points Per Curve = 20 Check Intermittent Contact box Select face ARROWS MUST POINT INSIDE SOLID Valve Cam Exercise

5.  Add Curve/Curve Intermittent Contact Points Per Curve = 20 Check Intermittent Contact box Add contact between valve and rocker Valve Cam Exercise

6.  Modify Contact Properties for both Contacts Ensure damping value and friction values are set according to dialog display Valve Cam Exercise

7.  Add a Linear Spring Pick origin for valve Pick origin for valve_guide Valve Cam Exercise

8.  Set Simulation Parameters Run Simulation Valve Cam Exercise

9.  Plot Results Cam and Rocker Contact Force Valve and Rocker Contact Force Valve Cam Exercise

10.  Modify Spring  Stiffness = 150 N/mm  Free Length = 45 mm  Re-run Simulation Contact Between Valve and Cam Valve Cam Exercise
