Also, in a few cases, the desired output motion of follower is already known so it became simple to generate a cam profile from the known follower rise function. New Equipment Digest.
Geometry of a valve-opening mechanism with a rocker arm and radial cam. When working with multibody systems, you may need to model a mechanism that transfers motion from one component to another.
These are: This means that the motion to the follower is due to the profile height of the cam. Since the point is fixed to the body, the elements of the vector are constant in the body-fixed coordinate system, while in the global coordinate system, they vary with the rotation.
Log Out. Classifying the Different Types of Cam-Follower Mechanisms Cam-follower mechanisms are categorized based on the input and output motion of their configurations. If possible, use a fine mesh on a cam boundary to improve the accuracy of the mesh normal used in the Cam-Follower connection node.
In this the follower oscillates about a hinge point as the cam rotates. Roller followers are commonly used in large stationary gas or oil engines and aircraft engines.
Types Of Follower. Acceleration is the rate of change of velocity over time.
The Radial - Translating Follower: In this mechanism, the cam rotation is prescribed and a spring is attached to the valve to restrict its motion. The Flat-Face follower: There are many ways to transform one type of motion into another. Consider a simple knife edge radial follower with a known follower rise and a cam angle rotation.
In other words, the contact is unique and occurs at a single point. Schematic of the generated cam profile.
