RETRACTOR

Connection type RETRACTOR joins the position of two nodes and provides a FLOW-CONVERTER constraint between the material flow degree of freedom (10) at the second node and the rotational degrees of freedom at the first node of the connector. This connection type can be used to model retractor and pretensioner devices in automotive seat belts (see Seat belt analysis of a simplified crash dummy) or cable drums in winch-like devices.

RETRACTOR connections cannot be used in two-dimensional and axisymmetric analyses in Abaqus/Explicit.

Description

Figure 1. Connection type RETRACTOR.

Connection type RETRACTOR imposes kinematic constraints and uses local orientation definitions equivalent to combining connection types JOIN and FLOW-CONVERTER.
