OS-T: 1950 Curve to Curve Constraint
In this tutorial, you learn how to model a CVCV (curve-to-curve) joint using HyperMesh
In this tutorial, a Curved Pentagon Positive Return Cam system is modeled with the help of a CVCV constraint.
Launch HyperMesh and Set the OptiStruct User Profile
Open the Model
Set Up the Model
Create Rigid Bodies (PRBODY)
PRBODY is the Rigid Body Definition for Multi-body Simulation. PRBODY defines a rigid body out of a list of finite element properties, elements and grid points.
There will be five bodies apart from the ground body in our model via: the stand, the slider, the driver, the pentagon and the circle. Pre-defined free nodes will be used to define the bodies and joints.
Create Joints
In this step you will create all of the joints needed for the model.
Joint Type | Removes translational dof | Removes rotational dof | Removes total number of dof |
---|---|---|---|
Revolute | 3 | 2 | 5 |
Fixed | 3 | 3 | 6 |
Translational | 2 | 3 | 5 |
Motion (rev) | 3 | 2 | 1 |
Define the Motion Constraint
Create Load Collectors
In this step you will create the gravity force that applies to the model and MBSIM Bulk Data card, which is to specify the parameter for multibody simulation.

View the Results
In this step you will view the results in HyperView, which will be launched from within the OptiStruct panel of HyperMesh.
HyperView is a complete post-processing and visualization environment for finite element analysis (FEA), multibody system simulation, video and engineering data.
