Geometry and model
In this example problem the mechanism consists of three bodies named PIN
, SLOT1
, and SLOT2
, as illustrated in Figure 1. SLOT1
is an analytical rigid surface that overlays SLOT2
. SLOT2
is modeled as a display body. SLOT1
and SLOT2
are rigidly joined to each other at point A so as to allow them to rotate in unison about A. SLOT2
has a radius of 3.0 units and is 1.0 units thick. The pin is constrained to be rigid. The thickness of the rigid part of PIN
is 0.5 units. The rigid portion of PIN
has a reference point B, and PIN
is allowed to rotate about B. Distance AB is 4.24264 units in the model. The protruding portion of PIN
is located at a distance of 3.0 units from reference point B, and its length is 1.0 units. The rigid portion of PIN
has a radius of 3.0 units.
