Investigation Of Cam Mechanisms

Cam Mechanisms play an important role in the conversion of rotary motion into oscillatory motion. The most common application of cam mechanisms is the activation of valves in engines. This application is highly dynamic: valves must be opened and closed in very quick succession. The contact between the valve and a cam must not be lost, otherwise it would result in uncontrolled oscillations, valve float and possible damage to the engine.

Learning Objectives And Experiments

1. Elevation curves in non-matching engaging member
2. Elevation curve in sprung-engaging member
3. Determine the limit speed and compare with theory
4. Influence of moving mass on the motion of cam member/plunger
5. Influence of return-spring stiffness and preload on the motion of cam member/plunger
6. Comparison of the elevation curves of different cam-member shapes
7. Comparison of elevation curves with theory

Features

1. Record elevation curves of cam mechanisms
2. Four different cam members, two different engaging members
3. Influence of spring stiffness and mass on the dynamic behaviour
