Road Reference Marker
In this tutorial you will learn how to modify the road property file and road reference marker to position a cleat road in a single tire model.
- Introduction
-
Road reference marker is the coordinate system that is used by MotionSolve to evaluate the position and orientation of the road. The road file will be evaluated with respect to the road reference marker which is also included in the Tire entities selectors.
- Road Reference Marker - Cleat Road Model
-
The Cleat Road is represented by a flat road with a single cleat (cuboid obstacle) that can be oriented in perpendicular or oblique direction related to the X-axis of the Road Reference Marker.
In the road property file,
Offset
is the distance of the ground with respect to the Z-axis of the Road Reference Marker.Length
measures the width of the cleat along X-axis.Rotation angle XY plane
is the positive X-axis of the road with respect to the inertial frame.Start
indicates the distance along the X-axis of the road from the origin to the start of the cleat.In this tutorial you will learn how to modify the road property file and road reference marker to position the cleat road in a single tire model. By plotting the tire forces versus the tire patch location, you will understand the influence of the marker and road property in the simulation results.
