RDF File Format

 

The format for Road Data File (RDF) has two types. One is a RecurDyn Generated Road File format, the other is a user-defined Road file format.

 

RecurDyn Generated Road Data File Format

This road data file is automatically generated by RecurDyn after simulation, it also can be imported by Import Road.

The following table explains the format of the Road Data file.

 

GENDATA

The information about the road in the general road profile format.

X_SCALE

 

real

Conversion Factor.

Y_SCALE

 

real

Conversion Factor.

Z_SCALE

 

real

Conversion Factor.

ORIGIN

Coordinates of the road origin with respect to the global reference frame.

x, y, z

 

UP

A vector that indicates the upward side of the road in the global reference frame.

x, y, z

 

ORIENTATION

Transformation matrix which is oriented to the road coordinate system with respect to the global reference frame.

x1, y1, z1

 

x2, y2, z2

 

x3, y3, z3

 

NODES

 

Number of nodes (N)

Integer number of nodes.

Node_1, x_1, y_1, z_1

Location of Node 1.

Node_2, x_2, y_2, z_2

Location of Node 2.

Node_n, x_n, y_n, z_n

Location of Node n.

ELEMENTS

 

Number of elements (Ne)

Integer number of elements.

NodeA_1, NodeB_1, NodeC_1, U0_1, U1_1

Nodes which are consisted of triangle element 1.

NodeA_2, NodeB_2, NodeC_2, U0_2, U1_2

Nodes which are consisted of element 2.

NodeA_n, NodeB_n, NodeC_n, U0_n, U1_n

Nodes which are consisted of element n.

 

     Example

 

User Defined Road Data File Format

This road data file is defined by only user. So, RecurDyn does not generate this Road File. And it can be imported by Import Road on the Road Data group.

The following table explains the format of the user-defined Road Data file.

 

[UNITS]

The information about the unit in the road file.

LENGTH

Definition of the length unit.

[PARAMETERS]

Information about road parameters.

START_POSITION

Definition of the start position for the road data

NORMAL_DIRECTION

Definition of the normal direction for the road data.

DRIVING_DIRECTION

Definition of the driving direction for the road data.

OFFSET

Vertical offset to the ground with respect to the inertial frame.

WIDTH

Definition of the width between two outlines.

(DATA)

Definition of the road data points.

direction

Definition of the position along the driving direction.

left

Definition of the position to the left side with respect to the driving direction.

right

Definition of the position to the right side with respect to the driving direction.
