28.2.5. Flat Type
A Flat Type is a geometric entity that is defined by a cylinder. The width and radius of the contact surface of Flat Type must be large enough for the track link to pass. The roller of flat type is used for small size hydraulic excavators as the carrier roller and supports the track assembly.

28.2.5.1. Modeling Options
The user can create a flat type flange as follows.
Point, Distance
Point: Selects a point to define the center of the flat type flange.
Distance: Defines a distance of the flat type flange.
28.2.5.2. Properties
Figure 28.31 Flat Type property page [Characteristic page]
The Flat Type property page is shown in Figure 28.31. The parameters are explained below. In order to understand the geometry, refer to Dimension Information.
Roller Width (W): Enters the width of roller.
Roller Radius (R): Enters the radius of roller.
Full Search: All links are searched for contact.
Partial Search: Some links are searched for contact in some boundary. It is used to reduce total solving time.
User Boundary: Defines the radius of neighbor range.
Contact between a Flat Type Flange and Track Links
The flat type is in contacts with the track link in the one part.
