Pin Connectors

You can use pin connectors to simulate the behavior of pins in an assembly without modeling the actual pin geometries.

An assembly consists of multiple parts connected to each other with pins, bolts, screws, or springs. Examples of assemblies with pins include laptops, scissors lifts, pliers, and actuators. To simulate such assemblies, traditionally, you would need to create each pin geometry and apply contact conditions between the pins and their contacting faces. This is a computationally expensive approach.

In applications where you want to know the effects of pins on adjacent parts rather than the stress distribution of the pins themselves, use pin connectors to simulate the behavior of the pins.

You can define a single pin connector attached to multiple coaxial cylindrical faces or shell edges (maximum of 10 selections).

In the Connector-Pin PropertyManager, for Cylindrical Faces/Edges , select all coaxial cylindrical faces (or edges) that are attached to the pin (maximum of ten). The selected cylindrical faces or circular edges can belong to one body or to several bodies.

When to Use Pin Connectors

Define one pin connector that acts as a hinge to connect the three plates.
Define a pin connector to connect the two cylindrical faces that rotate against each other. Allow the cylindrical faces to rotate against the pin, but prevent them from moving axially with respect to each other.
Define one pin connector to connect the six cylinders of the hinged plate.
Define a pin to connect the two rotating parts. One pin connector attaches to four cylindrical faces.
